Woody Plants for Shade Part 4

Posted in Camellias, evergreen, flower show, Shade Shrubs, shade vines, winter interest with tags , , , , , , , , , , , , , , , , , , , on March 23, 2012 by Carolyn @ Carolyns Shade Gardens

Carolyn’s Shade Gardens is a retail nursery located in Bryn Mawr, PA, specializing in showy, colorful, and unusual plants for shade.  The only plants that we ship are snowdrops within the US.  For catalogues and announcements of local events, please send your full name, mailing address, and cell number to carolyn@carolynsshadegardens.com and indicate whether you are interested in snowdrops, hellebores, and/or hostas.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

Spring-blooming camellia ‘Pink Icicle’

For years, my customers have been asking for woody plants for shade—trees, shrubs, and vines—in addition to the perennials I sell.  I now have a wholesale woody plant nursery with the quality and selection I needed to be able to offer them at Carolyn’s Shade Gardens.   I have just sent out my first 2012 list.  To view the catalogue, click here.   However, I thought my blog readers who are not customers might be interested in learning about the plants that I would recommend they add to their shade gardens.  And doing an article allows me to add more information and explain why I chose the plants I included so customers might be interested also.

Spring-blooming camellia ‘April Tryst’

The offer focuses on winter- and early spring-blooming plants, evergreens, and fragrance.  Included are three camellias, six other shrubs, and one vine.  Four of the plants I have chosen are evergreen, and seven bloom in the off season: late winter or early spring.   This reflects  my desire to see gardeners expand their gardens’ season beyond spring and summer to become a year round paradise for them to enjoy.  With that introduction, here are the plants I am highlighting:

The buds are just starting to expand on ‘April Snow’ camellia.


I included three hardy camellias for their spectacular early season flowers and elegant evergreen leaves. These camellias, along with many other cultivars, have been bred to be fully cold hardy in the mid-Atlantic U.S, zones 6B and 7A.  Nevertheless all camellias benefit from being sited to shelter them from winter wind, which comes from the northwest.  They also maintain their lustrous dark green leaves in better shape if they are sheltered from winter sun.  For more information on cold hardy camellias for our area, click here.

‘April Snow’ spring-blooming camellia

Camellia x ‘April Snow’ is a spring-blooming hardy camellia with gorgeous plump buds opening to large pure white rose-form double flowers in April and May.  It has large glossy dark evergreen leaves.  It is 5’ tall and 4′ wide, growing in part to full shade.  It is part of the April series of exceptionally hardy camellias developed by Dr. Clifford Parks of North Carolina.

 

‘April Tryst’

‘April Tryst’ is very similar to ‘April Snow’, reaching 5′ tall and 4′ wide at maturity and sporting lustrous dark evergreen leaves in part to full shade  However, it blooms earlier, in March and April, and has knock-your-socks-off red anemone form flowers.  It is also part of the April series of exceptionally cold hardy camellias.  ‘April Tryst’ was starting to bloom in Charles Cresson’s garden during our recent Winter Interest Seminars, and Charles highly recommends it.

‘Pink Icicle’

Spring-blooming camellia ‘Pink Icicle’ has very large, peony form, shell pink flowers that glow when displayed against the glossy evergreen leaves.  It blooms in March and April in part to full shade.  It has a compact and upright growth habit and was selected by Dr. William Ackerman at the U.S. National Arboretum.

Japanese mahonia, Mahonia japonica

amazingly fragrant flowers of Japanese mahonia

The final evergreen plant is Japanese mahonia, Mahonia japonica.  Aside from being evergreen, this was the most fragrant plant in the Cresson garden during the Winter Interest Seminars, and there was plenty of competition.  In February and March, extremely fragrant yellow flowers on 8” racemes cover Japanese mahonia.  The evergreen leaves are a dark glossy green with a finer texture than other mahonias, and they rarely get damaged in winter. The  glaucous blue fruit in early summer attracts birds.  Japanese mahonia grows to 6′ tall and 3′ wide in moist, well-drained soil.  It is also deer resistant.  For more information, click here.

‘Jet Trail’ flowering quince

There are five deciduous shrubs in the offer, including two flowering quinces.  Now I love the early flowers, beautiful colors, and deer resistance of quince, but it is difficult to fit a 10′ plus tall and wide shrub covered with lethal thorns into the garden.  That’s why I was excited when new low and compact quinces that won’t dominate your garden were introduced.  They are not marketed as thornless, but I can’t find any thorns on mine.  As an added benefit, the leaves remain healthy all summer.

‘Texas Scarlet’ flowering quince

‘Jet Trail’ and ‘Texas Scarlet’ flowering quince, Chaenomeles x superba, are identical plants other than their flower color, growing 3’ tall and 3’ wide in sun to part shade.  They produce multitudes of very showy white or coral red flowers in March, which are beautifully displayed by the elegant branching structure.  The  glossy dark green leaves stay ornamental through the season.  The  yellow fruit is wonderfully fragrant.  Both cultivars will grow well in clay soil and drought conditions.  For more information, click here

Spike winter hazel, Corylopsis spicata

Spike winter hazel, Corylopsis spicata, is the elegant shrub with the unusual yellow flowers that everyone admires in my garden in early spring. Dangling panicles of very fragrant, lemon yellow flowers cover this graceful shrub in March and April before the foliage.  The bold-textured leaves emerge burgundy and age to a lovely blue-green.  Winter hazel grows to 8′ tall and 6′ wide in full sun to part shade.  It takes average garden soils and is deer resistant; for more information, click here.

fall color of fothergilla

Native ‘Blue Shadow’ fothergilla, Fothergilla x intermedia, has stunning ornamental attributes three seasons a year.  In March and April, it is covered with honey-scented white bottlebrush flowers.  Its gorgeous dusty blue leaves provide an unusual color and texture for the shade garden.  In the fall, the foliage turns lovely shades of yellow, orange, and red.  ‘Blue Shadow’ grows to 4′ tall and 3′ wide in full sun to part shade.  It is native to the southeastern U.S., wet site tolerant, and deer resistant.  For more information, click here.

Snowball flowers of ‘Cayuga’ Koreanspice viburnum

‘Cayuga’ Koreanspice viburnum, Viburnum x ‘Cayuga’, is a cross between a smaller Koreanspice viburnum (V. carlesii) and the fragrant snowball viburnum (V. x carlcephalum) introduced by the U.S. National Arboretum.   It has the best attributes of both.  In April and May, striking pink buds open to abundant, fragrant, large white snowball flowers.  It has a compact habit with dark green leaves that change to orange-red in the fall.  It grows to 6′ tall by 5′ wide in full sun to part shade.  ‘Cayuga’ tolerates a wide range of soils and is deer resistant.  For more information, click here.

Climbing hydrangea, photo courtesy of the Missouri Botanical Garden.

The final plant in the offer is a vine.  Climbing hydrangea, Hydrangea anomala subsp. petiolaris, is really the best vine for shade with 365 days of ornamental value.  Its lustrous, dark green leaves are neat and attractive all season before turning a buttery yellow in the fall.  In June and July, fragrant 8” wide hydrangea-like white flowers layer over the leaves.  The exquisite exfoliating cinnamon bark provides winter interest.  Climbing hydrangea is self-attaching and reaches 30 to 50′ at maturity in part to full shade.  It is a Missouri Botanical Garden Plant of Merit.  For more information, click here.

I grow most of these plants in my gardens so I know you can’t go wrong by adding them to yours!  If you are a customer, see Nursery Happenings below for details on how to order these wonderful shade plants by noon on March 26.  If not, now you have some plants to ask for at your local independent nursery.  If you would like to read about the other woody plants I have recommended for shade, see Part 1, Part 2, and Part 3.

Species Hellebores for 2012

Posted in evergreen, hellebores, Shade Perennials, winter interest with tags , , , , , , , , , , , , on March 8, 2012 by Carolyn @ Carolyns Shade Gardens

Carolyn’s Shade Gardens is a retail nursery located in Bryn Mawr, PA, specializing in showy, colorful, and unusual plants for shade.  The only plants that we ship are snowdrops within the US.  For catalogues and announcements of local events, please send your full name, mailing address, and cell number to carolyn@carolynsshadegardens.com and indicate whether you are interested in snowdrops, hellebores, and/or hostas.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

‘Josef Lemper’ Christmas rose, Helleborus niger, has very large flowers and blooms from November into May depending on the weather.

In my post New Hellebores for 2012, I profiled all the exciting new hybrid hellebores that I am offering this spring.  If you haven’t read it, there are some gorgeous photos.  Now I want to show you the species hellebores that are available at my nursery this year.  In a third post, I will describe what I call the “species crosses” that you can add to your garden this spring.


The Christmas rose ‘Jacob’ is loaded with flowers from November through late spring.

In The Sex Lives of Hellebores, I described the difference between hybrid hellebores, the subject of my February 2012 new hellebore post, and the roughly 15 types of species hellebores.  I sell most of the species by special order, but here I want to profile the five that I will be featuring this year.  My favorite is Christmas rose, Helleborus niger.  Despite its name, I used to have to wait until March to view its lovely pure white flowers.  With the introduction of the cultivars ‘Josef Lemper’ and ‘Jacob’, which reliably start blooming in November, you can now have Christmas roses blooming for Christmas.

 

Christmas rose flowers age to a lovely pink: ‘Jacob’ with fall-blooming camellia ‘Winter’s Joy’.


Christmas roses have many desirable attributes which I described at length in Christmas Rose: The Perfect Hellebore.  Their outward facing, pure white flowers are framed by lovely blue-green leaves that stay ornamental through winter.  They are deer resistant like hybrid hellebores but are smaller and have a more refined look than the hybrids.  For more information on ‘Jacob’ and ‘Josef Lemper’, see
Hellebores for Fall.

Double Christmas rose, Helleborus niger ‘Double Fantasy’

I am very excited to be able to offer ‘Double Fantasy’, a fully double Christmas rose developed through tissue culture by a nursery in Japan.  Before it was introduced in 2011, I had only seen one double (in Charles Cresson’s garden), and double Christmas roses were not available for sale.  Its flowers are magical.

 

Fragrant hellebore, Helleborus odorus

The next three species, H. odorus, H. purpurascens, and H. viridis, were all profiled in depth in The Sex Lives of Hellebores because they are all parents of the hybrid hellebores.  However, they are gardenworthy in their own right and have attributes the hybrids don’t have.  I am a big fan of green flowers, and fragrant hellebore, H. odorus, has striking yellow-green flowers with a delicious scent that is pervading my garden right now.  It looks especially nice when grown with dark purple hybrids.

flower of Helleborus purpurascens

Helleborus purpurascens, which has no handy common name, is another one of my favorites.  The colors mixed in its flowers, blue-green and a silvery, smoky purple, have not been duplicated in any of the hybrid flowers.  I would also grow it just for its circular, filigreed leaves:

 

Helleborus purpurascens


outside of H. purpurascens flower

Green hellebore, H. viridis, has the purest green flowers of almost any plant I grow.  It is also shorter and more compact than the hybrid hellebores and the other species.  It too looks great with dark purple to black flowers, but my favorite combination features green hellebore with a drift of the true blue flowers of brunnera—heaven:

 

Green hellebore, H. viridis

flower of green hellebore

The final species that I will be offering this spring is bearsfoot hellebore, H. foetidus.  I profiled this plant in detail in Hellebores for Fall.  Bearsfoot has the most ornamental leaves of any hellebore, and they are truly wintergreen coming through ice and snow looking pristine.  Bearsfoot forms its lovely chartreuse buds in the fall.  The flowers open in winter and remain ornamental until it gets hot.  It is also taller than other hellebores, reaching two feet or more and giving it the stature of a small shrub:

 

Bearsfoot hellebore, H. foetidus

 

unusual, evergreen leaves of bearsfoot hellebore

When I started this post, I thought I would be able to fit the seven species above plus the five “species crosses” I will also be selling this spring.  You know me though: I get excited about hellebores.  By the time I included all the photos I wanted, the post was long enough.  Look for a third post with some exciting crosses, all with Christmas rose as a parent.

2012 Winter Interest Plants

Camellia japonica ‘Berenice Boddy’ in full bloom in February in the Cresson garden.

On Friday, February 24, and Monday, February 27, Charles Cresson presented the second annual Winter Interest Plant Seminars for my customers in his beautiful garden located in Swarthmore, Pennsylvania, US.  I did a post on the seminars last year (to read it click here) and thought I had covered the topic.  However, our very warm winter meant that many different plants were in bloom so I want to show you what we saw.


The weather was cold and rainy on Friday, but participants didn’t let it stop them from enjoying Charles’s presentation.

Monday was warm and sunny which allowed more time for dawdling in the garden.  The snowdrops were a big hit.

The attention to detail in Charles’s garden is amazing.  I thought I would show you some of the “hardscape” features, many of which Charles built himself:

 

The rock garden with hellebores, Algerian iris, and spring-blooming hardy cyclamen.

Garden shed with the original green roof.

Winter jasmine, Jasminum nudiflorum, photo by seminar participant Lucretia Robbins.

Charles has a spectacular collection of winter-blooming shrubs, many of which are fragrant.  We were all surprised by which one was the most fragrant at that time of year:

 

Chinese holly, Ilex cornuta, retains its berries through the winter.

 

 

Sweetbox, Sarcococca hookeriana var. digyna ‘Purple Stem’, adds the additional feature of ornamental stems to sweetbox’s many desirable attributes.

 

 

Bodnant viburnum, V. bodnantense ‘Dawn’, is very fragrant.

 

 

Flower of Bodnant viburnum

 

The adult form of English ivy, Hedera helix ‘Poetica Arborea’, produces beautiful berries but is also considered very invasive.

 

Camellia x ‘April Tryst’ is blooming early.

 

I like the male flowers of Japanese skimmia, S. japonica, as much as the berries on the female plants.

 

 

Winter daphne, D. odora, is one of my favorite shrubs because of its wonderful fragrance, excellent habit, evergreen leaves, and lovely flowers.

 

And the winner is….  Yes, Japanese mahonia, M. japonica, was the most fragrant plant in Charles’s garden even with all the excellent competition above.

Winter-blooming herbaceous perennials were also well represented:

The pink flowers and evergreen leaves of heath, Erica x darleyensis ‘Furzey’.

Evergreen heart leaf ginger, Asarum virginicum

Fragrant Algerian iris, I. unguicularis, was a big hit.

Christmas rose, Helleborus niger, photo Lucretia Robbins

A gorgeous anemone-flowered (ruffle around the center of the flower) hybrid hellebore—my favorite type of hellebore flower.

The most evergreen hellebore of them all, bearsfoot hellebore, H. foetidus.

Helleborus x ericsmithii ‘Winter’s Song’

Hybrid hellebore with the very robust and extremely fragrant snowdrop ‘Brenda Troyle’.

The tour included a wonderful selection of winter-blooming bulbs, including choice snowdrop cultivars.  Here are just a few:

Seeing this large patch of the very fragrant snowdop ‘S. Arnott’ sent participants back to add it to their purchases for the day.

Spring-blooming hardy cyclamen, C. coum

The common snowdrop, Galanthus nivalis, multiplies quickly and looks great when massed.

Evergreen leaves of fall-blooming hardy cyclamen, C. hederifolium

A single bulb of a rare yellow-flowered cultivar of the species snowdrop, G. woronowii, just sold for $1,145 on UK eBay.

A silver-leafed form of spring-blooming hardy cyclamen.

The species snowdrop Galanthus plicatus has been in cultivation since the 16th century and comes from Russia and Turkey.  It has beautiful leaves with a unique folded (explicative) pattern.

For all of you who couldn’t actually attend Charles’s seminars, I hope you have enjoyed your virtual tour.

A Wonder of Nature

Posted in bulbs for shade, garden to visit, Shade Perennials, winter, winter interest with tags , , , on February 21, 2012 by Carolyn @ Carolyns Shade Gardens

Carolyn’s Shade Gardens is a retail nursery located in Bryn Mawr, PA, specializing in showy, colorful, and unusual plants for shade.  The only plants that we ship are snowdrops within the US.  For catalogues and announcements of local events, please send your full name, mailing address, and cell number to carolyn@carolynsshadegardens.com and indicate whether you are interested in snowdrops, hellebores, and/or hostas.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

Winter aconite, Eranthis hyemalis

One of the first plants to bloom in my garden is winter aconite.  It usually starts blooming in February and continues into March.  I treasure its cheery yellow flowers with their shiny green collars because they brighten what can otherwise be a cold and dreary time of year.


When my original winter aconite plants got this big, I was thrilled.

Winter aconite is in the buttercup family and is native to Europe.  It is about four inches tall and prefers woodland soil in deciduous shade.  It wants to be cool in the summer but not too dry, and it will not tolerate wet soil.  It grows in zones 3 to 7.  Winter aconite is a bulb (technically a tuberous rhizome) and goes dormant when the weather gets hotter.  Some sources state that it is poisonous to humans, but there have been no reported incidents.  It is deer resistant and black walnut tolerant.

 

When the patch started to fill in like this one I was ecstatic.

You can order winter aconite as a dried bulb.  It is recommended that the bulbs be soaked overnight to increase success.  Despite soaking, I never got more than one or two bulbs to grow into plants.  I tried several times.  Then a friend of mine gave me some growing plants (thanks Julie!), and my little patch of winter aconite began in earnest.

 

After several years, my patch looked like this.

Winter aconite naturalizes well once you get the initial plants going.  The best way to spread it is to collect the seeds and sprinkle them where you want them.  If you don’t collect the seeds, they tend to germinate around the base of the mother plant.  My winter aconite has been so successful that, after ten years,  I was able to sell growing plants in my snowdrop catalogue (although next year I need to give the patch a “rest”). 

 

Winter aconite covers this much ground in my woodland.

Now we get to the “wonder of nature” part.  Right down the street from my plant nursery is a public park owned by Radnor Township (Pennsylvania, US) called Ithan Valley Park.  The property was originally an old Main Line estate.  During the early 1900s, it was owned by the botanist John Evans, and he maintained an arboretum of exotic plants there.  Evidently his collection was amazing, but today few of the original plants remain.

 

Winter aconite in Ithan Valley Park

At some point John Evans planted winter aconite on his property.  The conditions there proved to be ideal with the cool, moist woodland soil and deciduous shade that winter aconite loves.  Today Ithan Valley Park is covered with sheets of winter aconite every February and March.  There is so much yellow that I think it must be visible from outer space.  It truly is a wonder of nature that I want to share with you.

 

The winter aconite in the park grows thickly.

 

 

 

Trail entrance, Ithan Valley Park

 

The stone wall of the old estate is in the background.

 

To truly appreciate the spectacle, you need to visit in person (I apologize to my non-local readers).  Ithan Valley Park is located at 642 South Ithan Avenue, Bryn Mawr, PA  19010, at the intersection of South Ithan and South Roberts Roads.  Time is of the essence because the winter aconite will only be blooming for a few more days.

I am linking this post to the Winter Walk-off 2012, which is a challenge by Les at A Tidewater Garden to share what can be seen within walking (or biking) distance of your home.  Every photo in this post was taken at Ithan Valley Park, 8/10 of a mile from my house.

February GBBD: New Hellebores for 2012

Posted in evergreen, Garden Blogger's Bloom Day, hellebores, Shade Perennials, winter, winter interest with tags , , , , , , , , , , , , , , , on February 12, 2012 by Carolyn @ Carolyns Shade Gardens

Carolyn’s Shade Gardens is a retail nursery located in Bryn Mawr, PA, specializing in showy, colorful, and unusual plants for shade.  The only plants that we ship are snowdrops within the US.  For catalogues and announcements of local events, please send your full name, mailing address, and cell number to carolyn@carolynsshadegardens.com and indicate whether you are interested in snowdrops, hellebores, and/or hostas.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

‘Phoebe’ is a beautiful double hellebore selected by Dan Hinkley formerly of Heronswood Nursery in Kingston, WA, as were most of the hellebores pictured here.  They are all superior forms.

It is the middle of the month and time to participate in Garden Blogger’s Bloom Day (“GBBD”) hosted by May Dreams Gardens (link available on February 15) where gardeners from all over the world publish photos of what’s blooming in their gardens.  I participate because it is fun and educational for me to identify what plants make my gardens shine at different times of the year.  This month I hope that my nursery customers and blog readers will get excited about adding colorful hellebores to their own shade gardens to extend the garden season through winter.

My garden is located in Bryn Mawr (outside Philadelphia), Pennsylvania, U.S., in zone 7A (old 6B).


I grow the double ‘Elegance White’ for its distinct reddish purple spots and its symmetrical pointed leaves.

Because of the mild weather, I am overwhelmed with work at my nursery and behind on blogging.  So I am combining my GBBD post with a post on all the gorgeous new hybrid hellebores I will be offering this spring at my snowdrop and hellebore seminars and at my Hellebore Extravaganza on March 24.  They are coming into bloom right now so they definitely qualify for GBBD.  I will save the new species hellebores for a later post.

I decided to start with the doubles because, although I generally prefer single flowers, I love double hellebores.  Their flowers last for months.  In addition to the two above, I offer:

 

Hybrid hellebore “Double Rose”

 

Helleborus x "Double Purple"Hybrid hellebore “Double Purple”

My absolute favorite type of hybrid hellebore is known as anemone-flowered.  In this form, the nectaries around the center of the flower create a ruffle of mini petals matching the color of the flower.  I collect anemone-flowered hellebores (those of you who bought my calendar can see one in the February collage) but have never found them for sale.  I am thrilled to be able to offer one this spring:

 

The ruffle in the middle of this anemone-flowered hellebore picks up the beautiful colors of the larger petals (actually sepals).  Slate is also a very desirable hellebore color, and ‘Slate Anemone’ is similar to ‘Starling’, another Hinkley-selected hellebore.

I am also excited about the nine new single hybrid hellebores that Carolyn’s Shade Gardens will carry this spring representing every color of the rainbow.  I don’t know if I can pick a favorite:

 

‘Gold Finch’ has rounded petals of buttery yellow spotted with red flecks.

 

‘Black’ has striking near black flowers with a perfect rounded shape.

 

Helleborus x 'Pink Tea Cup'‘Pink Tea Cup’ is early-blooming with soft blush pink flowers reminiscent of cherry blossoms.

‘Raspberry Mousse’ has two-tone pale rose flowers with creamy white veins, and dark rose edges and reverse (the back of the flower).

‘Phoenix’ has apple green flowers edged in burgundy and with a burgundy center.

 

Slate gray petals with a metallic sheen and burgundy highlights in the center and veins make ‘Slate’ very desirable.

 

‘Painted Bunting’ has white flowers with a bold burgundy red central star, radiating red veins, and red picotee edges.

 

‘Velvet Lips’ has bright wine-red flowers with a soft creamy-yellow center and a shiny darker reverse.  I would buy this beautiful hellebore for the name alone.

The Yokoyama nursery in Japan has achieved the first ever cross between Christmas rose and hybrid hellebores to produce ‘Snow White’, this gorgeous early-blooming pure white hellebore with large, flat, outward-facing flowers; easy to grow like all the hybrids but easy to see the flowers too!

I tested all these hellebores in Spring 2011 by planting them in my garden.  This year I am being rewarded with big healthy plants loaded with flowers.  Stop by and see for yourself after I open on March 15.

Carolyn’s Shade Gardens Goes International

Posted in bulbs for shade, snowdrops, winter, winter interest with tags , , , , , , , , , , , , on February 3, 2012 by Carolyn @ Carolyns Shade Gardens

Carolyn’s Shade Gardens is a retail nursery located in Bryn Mawr, PA, specializing in showy, colorful, and unusual plants for shade.  The only plants that we ship are snowdrops within the US.  For catalogues and announcements of local events, please send your full name, mailing address, and cell number to carolyn@carolynsshadegardens.com and indicate whether you are interested in snowdrops, hellebores, and/or hostas.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

The BBC News Magazine was hours away from publication when they emailed to request a photo of me with snowdrops.  My husband and I had a quick photo shoot and this is what we came up with.

We interrupt the regularly scheduled flow of posts on this blog with breaking news.  The owner of Carolyn’s Shade Gardens is prominently featured in the BBC News Magazine lead article for February 2 entitled “Snowdrop Fanciers and Their Mania”. 

All kidding aside, I couldn’t be more thrilled.  I am in the company of Matt Bishop and John Grimshaw, two of the authors of the “snowdrop bible” Snowdrops: A Monograph of Cultivated Galanthus, and Chris Ireland-Jones, the owner of the famous English snowdrop nursery Avon Bulbs.  You know what a snowdrop fanatic I am so this is the ultimate compliment.  To read the article (I am in the second half), click here.

Second Annual Snowdrops & Other Winter Interest Plant Seminars

Charles Cresson pointing out some of his very unusual snowdrop cultivars to last year’s seminar attendees.

I am very excited that winter interest plant expert and gardener extraordinaire Charles Cresson has agreed once again to give seminars on Snowdrops and Other Winter Interest Plants just for my customers.  The seminars will be limited to 20 people each and will take place in his amazing Swarthmore garden, Hedgleigh Spring.  The brochure telling you the details and how to sign up is here.  If you are a local gardener and interested in attending, I encourage you to email immediately because I expect these seminars to sell out.  For a complete description of the 2011 seminars with many photos, click here.

 

Since this post is about all things snowdrop, I thought I would show you the first snowdrops to bloom in my garden in 2012:

The very first snowdrop cultivar to open in my garden in 2012: ‘Kite’.  Notice the very long outer segments (petals).

 

Second to open was Galanthus plicatus ‘Augustus’ with its striking puffy rounded and quilted outer segments.

‘Magnet’ is open and swaying in the breeze on its unusually long and thin flower stems (pedicels).

The double common snowdrop ‘Flore Pleno’ is blooming even though it is usually one of the last snowdrops to open in the middle to end of March.

The aristocratic snowdrop ‘Atkinsii’, said to resemble the pearl drop earrings of Elizabeth I, is also flowering.

The common snowdrop, G. nivalis, is blooming a few weeks early.  I shot this picture to document the date they opened and had a funny feeling that something wasn’t right.  When I uploaded the photos to the computer I realized the plants in the front have four outer segments instead of three—very interesting.

The giant snowdrop, G. elwesii, has been flowering on and off since November, but this patch just opened this week.

I avidly read the Galanthus threads on the Scottish Rock Garden Club forum where galanthophiles from all over the world meet to obsess about snowdrops.  I highly recommend this forum if you are interested in snowdrops and want to learn more.  The forumists are some of the most knowledgeable galanthophiles around but very welcoming and eager to share their passion.  Several of them commented on the varied markings on the giant snowdrops pictured above which got me outside with my camera to record the marks.  Here is what I found:

Every flower in this collage is the same species, G. elwesii, and yet the green marks on the inner segments are all different, from the small single green mark on the middle  right flower to the mark that looks like a mustache and eyes in the middle of the bottom row.  Although I realize this will not excite most gardeners, at least everyone can see the amazing variety.  And variety is the spice of life.

 

 

I have recently been honored with the Versatile Blogger Award by four different blogs, and I want to thank them for the accolade.  I try to make my blog posts varied and yes versatile (able or meant to be used in many different ways), and I am glad that my efforts are appreciated.  I am not following the award rules, but instead letting you know who gave me the award in hopes that you will visit their blogs.  Here are the links and some information to entice you to visit them:

Graphicality–UK:  Helene is a very accomplished author.  You might want to check out her recent post on the book she published with her lovely photos of Kew Gardens.  Her current post talks about US grey squirrels invading Britain.

Green Place:  Sheila is in Chapel Hill, NC, and reflects on spirituality, nature and gardening.  She and I also share a love of Maine islands.

The Amateur Weeder:  For a very different perspective, Lyn gardens in Australia and her blog produces “seedlings from the mind of an inconstant gardener.”  I particularly liked her recent post called Designed by Nature.

Women and the Garden:  Patty writes about “the history of the garden and the various roles women played in that history,” and it is  all absolutely fascinating.  She doesn’t post often, but when she does you don’t want to miss it.  Her latest post is on Pomona, the roman goddess of fruiting trees and orchards.

Chanticleer in Winter: Texture

Posted in garden to visit, landscape design, winter, winter interest with tags , , , on January 28, 2012 by Carolyn @ Carolyns Shade Gardens

Carolyn’s Shade Gardens is a retail nursery located in Bryn Mawr, PA, specializing in showy, colorful, and unusual plants for shade.  The only plants that we ship are snowdrops within the US.  For catalogues and announcements of local events, please send your full name, mailing address, and cell number to carolyn@carolynsshadegardens.com and indicate whether you are interested in snowdrops, hellebores, and/or hostas.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

Chanticleer’s Teacup Garden in May

Chanticleer is a unique public garden in Wayne, Pennsylvania, U.S., which I have profiled in three previous articles.  The first, Chanticleer Part 1: A Pleasure Garden, gave an overview of this one-of-a-kind horticultural destination.  The second, Chanticleer Part 2: Garden Seating, focused on the huge variety of thoughtful seating areas in the Chanticleer gardens.  The third, Chanticleer Part 3:  Through the Seasons, showed the gardens as they evolve through spring, summer, and fall.

 

The Teacup Garden in January

To complete my series on Chanticleer through the year, I received special permission to visit the garden during the winter months when it is closed to the public.  As you can see from the photo above, all the “toys” are put away and most of the flowers and foliage are gone.  But the minute I stepped into the garden, the word TEXTURE appeared before me as if it was outlined in neon lights.  I have never had such an exciting visit to this garden because I saw it in a whole new way, and I hope I can communicate that to you.

I always admire the elegant mature trees when I visit, but without their leaves or any flower gardens to distract me, they really stood out.

Texture was also provided by smaller plants, but not the way I expected:

 


 



Hardscape, always a huge part of Chanticleer’s elegance and beauty, really dominated my visit:


 

 

 

The attention to detail in the paths, always a hightlight for me, was easier to see and appreciate:

I decided not to add captions to the photos in this post, but if you want more information just run your cursor over the photo.  The location of the Lady in the Lake is secret so you will have to find her for yourself.

I want to thank Bill Thomas, Chanticleer’s Director, for making this visit possible, Fran DiMarco, Administrative Assistant, for arranging it, and Joseph Henderson, Horticulturalist, for providing some needed conversation in the sun so I didn’t freeze to death.  I have been promised a visit in the snow, and I might take them up on it if we ever get any of the white stuff.

New Snowdrops for 2012

Posted in New Plants, Shade Perennials, snowdrops, winter, winter interest with tags , , , , , , , , , , , , , , , , , , , , , on January 19, 2012 by Carolyn @ Carolyns Shade Gardens

Carolyn’s Shade Gardens is a retail nursery located in Bryn Mawr, PA, specializing in showy, colorful, and unusual plants for shade.  The only plants that we ship are snowdrops within the US.  For catalogues and announcements of local events, please send your full name, mailing address, and cell number to carolyn@carolynsshadegardens.com and indicate whether you are interested in snowdrops, hellebores, and/or hostas.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

Who said all snowdrops look alike?  Some of my favorites: top row, L to R, ‘Wendy’s Gold’, ‘Blewbury Tart’, ‘Hippolyta’, ‘Flore Pleno’; middle, ‘Jaquenetta’, ‘Merlin’, ‘Lady Elphinstone’, ‘Augustus’; bottom, unknown, ‘Ophelia’, G. plicatus subsp. byzantinus, ‘Lady Beatrix Stanley’.

.

Our current snowdrop catalogue is on line here.

.

This article includes photographs and colorful descriptions of the 5 new snowdrops I am offering for sale in my 2012 Snowdrop CatalogueFor entertaining descriptions of most of the remaining 13 varieties offered in the 2012 catalogue, click here.

The hundreds of snowdrop cultivars out there range from a classic like ‘Atkinsii’ pictured above to…(see next photo)

In Snowdrops or The Confessions of a Galanthophile, I described my transition from someone who grows snowdrops to someone who is obsessed with them.  In Snowdrops: Further Confessions of a Galanthophile, I explained that most snowdrop cultivars can be appreciated as much for their colorful history as for their ornamental characteristics.  That history is contained in Snowdrops: A Monograph of Cultivated Galanthus by Matt Bishop, Aaron Davis, and John Grimshaw (Griffin Press 2006), commonly called the “snowdrop bible”.

Galanthus nivalis 'Blewbury Tart' at Carolyn's Shade Gardens…this crazy, modern double cultivar, ‘Blewbury Tart’, which looks like it’s having a bad hair day (I love it!).

The information in Snowdrops is not only interesting but also crucial to keeping straight all the available snowdrops.  Snowdrops describes over 500 cultivars, and the authors admit that it is now out-of-date, and a second volume is required (for details on Snowdrops 2, click here).  Snowdrops description of the cultivar along with the actual origin of the snowdrop plant in question both contribute to its provenance: the history of its ownership documenting its authenticity.  If a collector is purchasing an expensive plant, provenance is very important.

Snowdrop prices range from the very affordable (but no less desirable) common snowdrop, G. nivalis, pictured above with Italian arum and snow crocus, to…(see next photo)

…the highly collectible (with a price to match) ‘Wendy’s Gold’.

‘Brenda Troyle’, a new snowdrop from Charles Cresson in my 2012 catalogue, is a perfect example of how this works.  True ‘Brenda Troyle’ is a vigorous snowdrop admired for its well-proportioned, rounded flowers with flared and cupped outer petals (segments) and a strong fragrance of honey.  It received an Award of Garden Merit from the Royal Horticultural Society in 1960 for “outstanding excellence for ordinary garden decoration or use.”  Customers who attended Charles Cresson’s snowdrop seminars last year loved it.

Charles Cresson’s authenticated ‘Brenda Troyle’

But Snowdrops explains that ‘Brenda Troyle’ is very mixed up in the trade.  In fact, it is even unclear whether it was named after a character in Sir Walter Scott’s novel The Pirate or a staff member at an Irish nursery.  In cases like this, it is very important that the snowdrop display the desirable characteristics of the cultivar as Cresson’s stock does.  It is equally as important that the original stock was purchased from a reputable source and kept labeled since its purchase.  Charles got his plants from a bulb company started by the venerable Hoog family of Van Tubergen fame and conserves his whole snowdrop collection with the utmost care.

Galanthus ‘Tiny’

‘Tiny’ is a snowdrop that does not suffer from an identity crisis as Snowdrops states that almost every galanthophile in the U.K. grows it.  It is a diminutive form of the common snowdrop, G. nivalis, easily distinguished by its narrow leaves and elfin stature.  It is quite charming in a clump, which develops rapidly with this vigorous cultivar.  It also flowers later, extending the snowdrop season into late spring.

The subspecies byzantinus of G. plicatus is easily distinguished from subspecies plicatus by the two marks on its inner segments.


Unique provenance adds significantly to the desirability of a snowdrop as is the case with the Turkish snowdrop, Galanthus plicatus subsp. byzantinus.  This subspecies has beautiful wide pleated leaves and lovely plump flowers joined in an elegant overall habit.  It comes from a small area in northwestern Turkey, but is uncommon even there.  Subspecies byzantinus is an exceptionally good form of G. plicatus, hard to come by even in the U.K.

The elegant habit of G. plicatus subsp. byzantinus.

But the part of its provenance that is really exciting is that these plants originated from one of the most celebrated and important American snowdrop collections, the gardens at Winterthur.  As Henry Francis du Pont added plants to Winterthur, snowdrops became a focus.  In the 1930s, he purchased the parents of these very bulbs from Barr & Sons, a renowned bulb house that operated in Covent Gardens, London, from 1882 to 1956.  When Charles Cresson worked at Winterthur in the early 1990s, he was given plants of this unique snowdrop, and we are offering the offspring of those plants in the 2012 catalogue.  Now that’s provenance!

The Greatorex double ‘Hippolyta’ (photo by and used with the permission of Paddy Tobin).

The final two new snowdrops were both hybridized in the mid-twentieth century by the legendary but enigmatic snowdrop breeder Heyrick Greatorex and are known as Greatorex doubles.  Snowdrops makes an unflattering reference to a story that he spent World War II in a local pub.  However, further research reveals that, in addition to serving in WWII, he fought in World War I, was wounded at Lagincourt, and received the Victory and British Medals—a very distinguished record indeed.  If you would like to read more about him, click here.

Galanthus 'Hippolyta' photo Paddy Tobin‘Hippolyta’ (photo by and used with the permission of Paddy Tobin)

‘Hippolyta’ is the shortest of the many Greatorex double snowdrops, which Heyrick Greatorex developed by crossing the double common snowdrop, G. nivalis ‘Flore Pleno’, with the species G. plicatus to create large and vigorous plants.  He named them after characters in Shakespeare’s plays, Hippolyta appearing in A Midsummer Night’s Dream.  Although some of the Greatorex doubles are confused, ‘Hippolyta’ consistently produces neatly doubled, rounded flowers, combining a tightly compact inner rosette with cupped and flaring outer petals (segments)—a charming arrangement.  It received an Award of Garden Merit from the Royal Horticultural Society in 1970.

 

The Greatorex double ‘Dionysus’

The final member of the five new snowdrops in my 2012 Snowdrop Catalogue is ‘Dionysus’, also a member of the acclaimed series of double snowdrops developed by Heyrick Greatorex (although not a Shakespeare character).  ‘Dionysus’ is one of the taller and earlier flowering doubles in this series.  It has fewer inner segments  than other Greatorex doubles, and  they feature a large, deep green, inverted heart-shaped mark.  Evidently Heyrick Greatorex described ‘Dionysus’ as one of the best of his doubles for cultivation in the open garden.  Charles got his bulbs from the well known Oregon bulb authority Jane McGary.

Obviously, I find everything about snowdrops fascinating and hope I have communicated some of my infatuation to you.  If you are in the U.S. and want to order from the catalogue, just follow the directions for mail order.

I have had this gorgeous double purple hellebore in my garden for several years but it has never bloomed this early.  Photo 1/7/12

It is the middle of the month and time to participate in Garden Blogger’s Bloom Day hosted by May Dreams Gardens (link available on December 15) where gardeners from all over the world publish photos of what’s blooming in their gardens.  I participate because it is fun and educational for me to identify what plants make my gardens shine at different times of the year.  This month I hope that my nursery customers and blog readers will get some ideas for plants to add to their own gardens to extend their season through winter.

My garden is located in Bryn Mawr (outside Philadelphia), Pennsylvania, U.S., in zone 6B.


‘Mrs. Betty Ranicar’ is usually one of my first hybrid hellebores to bloom but this is early even for her.

Last January, the whole garden was under snow, and I didn’t even participate in GBBD.  This year couldn’t be more different with 7 days in the 50s (10C) and 6 days at 60 degrees (16C) or above since December 15.  Frankly, I find it extremely worrisome, but it means that I didn’t have to go searching for plants peaking between December 15 and January 15.  There are a few other plants worth featuring, but my hellebores are all blooming early so I call this post Hellebores on Parade.  For the benefit of my customers, I will note which hellebores will be for sale at Carolyn’s Shade Gardens (CSG) this spring.

 

‘Pink Tea Cup’ has the best pink color of any hybrid hellebore and was the first to come into bloom this season ( for sale at CSG this spring).  Photo 1/9/12

 

‘Jacob’ Christmas rose just keeps going and going with new white flowers appearing and mixing with the older pink flowers for a gorgeous effect, see below (for sale at CSG).  Photo 12/31/11

 

‘Jacob’ Christmas rose with Camellia x ‘Winter’s Joy’.  Photo 1/2/12

Flowers are emerging on the hellebore species cross ‘HGC Pink Frost’ (for sale at CSG).  Notice the dark red to burgundy highlights on the leaves and stems and the amazing color of the buds.  As noted in Cutting Back Hellebores, I leave the foliage on to make a nice backdrop for the flowers.  Photo 12/31/11

 

‘Praecox’ Christmas rose is also blooming at least a month earlier than usual.  Photo 12/31/11

 

The hellebore species cross ‘HGC Winter’s Song’ is now fully in bloom.  Photo 1/10/12

The rare species Helleborus dumetorum (no common name) continues to bloom (for sale at CSG).  It is deciduous so all the “leaves” in the photo are actually flower bracts.  The leaves will come up later.  Photo 12/31/11

This beautiful, pure white, outward-facing hellebore called ‘Snow White’ (aka ‘Snow Bunting’) is an extremely rare cross between hybrid hellebore and Christmas rose—something that was thought to be impossible (for sale at CSG).  Photo 1/9/12

 

The lighter chartreuse buds of bearsfoot hellebore, H. foetidus, are becoming more prominent and will remain ornamental through May (for sale at CSG).  Photo 1/10/12

 

Helleborus x "Double Purple"Another look at the hybrid hellebore “Double Purple” (for sale at CSG).  Photo 1/7/12

My new favorite this year, hellebore species cross ‘HGC Cinnamon Snow’ (for sale at CSG).  I like it so much that I decided to put it in a basket by my front door.  Photo 1/9/12

There are some other plants looking great in my garden besides hellebores.  Most of the fall-blooming camellias still have viable buds but no flowers open to show you.  They will continue to bloom if the weather cooperates.  Here are the non-hellebore stars:

My un-named Korean Camellia japonica, which blooms in the spring and fall, continues to produce flowers.  Photo 1/9/12

Camellia x ‘Elaine Lee’ also has buds, and look at those shiny leaves.  Photo 1/10/12

Camellia x ‘Winter’s Joy’ has been flowering since October and is still covered with buds but none are open right now.

The buds on my variegated winter daphne, D. odora ‘Aureomarginata’, are coloring up early.  It is the sole survivor of five shrubs I put in this spring.  Although I gave them excellent drainage, they just couldn’t tolerate all the rain we had in August and September.  One by one they wilted from too much water and died, while this one remained healthy.  Photo 1/9/12

If we have cold weather, winter jasmine, Jasminum nudiflorum, blooms in February, but right now it is opening flowers continuously.  Photo 1/10/12

Galanthus elwesiiThe only snowdrop in bloom right now is the giant snowdrop, Galanthus elwesii (for sale at CSG).  Photo 1/9/12

My fall-flowering snowdrop ‘Potter’s Prelude’ has finished blooming, but I wanted to show you its beautiful leaves (for sale at CSG).  Photo 1/1/12

On New Year’s Day, my husband and I went walking in the Pinetum at the Haverford College Arboretum, a wonderful local treasure.  We saw two unusual conifers with great texture that I wanted to share:

 

Longleaf pine, Pinus palustris, is native from Virginia to Texas but is not usually found around here.

 

I love firs, and the texture of this Algerian fir, Abies numidica, really stood out.

I dedicate this post to Bob Stewart, my friend and horticulturalist extraordinaire, who died on December 16, 2011.  Bob and his wife Brigitta started the amazing nursery Arrowhead Alpines in Fowlersville, MI.  If you haven’t visited their site, you should by clicking here.  Bob will be greatly missed.

Cutting Back Hellebores

Posted in evergreen, hellebores, Shade Perennials, winter interest with tags , , , , , , , , , , , , , , on January 4, 2012 by Carolyn @ Carolyns Shade Gardens

Carolyn’s Shade Gardens is a retail nursery located in Bryn Mawr, PA, specializing in showy, colorful, and unusual plants for shade.  The only plants that we ship are snowdrops within the US.  For catalogues and announcements of local events, please send your full name, mailing address, and cell number to carolyn@carolynsshadegardens.com and indicate whether you are interested in snowdrops, hellebores, and/or hostas.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

‘Jacob’ Christmas rose, Helleborus niger ‘Jacob’, right now in my garden.  It always starts blooming in the fall, see Hellebores for Fall.  Photo 1/1/12

I usually don’t think about cutting back my hellebores until mid-February when the flower stalks begin to extend up through the old leaves.  However, here in southeastern Pennsylvania, we have had unusually mild weather during December—10 days over 50 degrees (10 C) and 8 days at 60 degrees (16C).  Hellebores that don’t usually bloom until February are coming into bloom now.  It seems like a good time to explain the ins and outs of cutting back the old leaves on hellebores.  This is done for aesthetic reasons and is not necessary for the health of the plant.


This beautiful hybrid hellebore, H. x hybridus ‘Pink Tea Cup’, is fully out right now.  It usually blooms in February.  Photo 12/31/11

The genus Helleborus contains about 15 species, and decisions about how to care for them require some knowledge of exactly which hellebores you have and how they grow.  The most commonly available hellebores are hybrid hellebores, Helleborus x hybridus (the Royal Horticultural Society approved name, previously called Lenten rose),  with the large, showy, nodding flowers in an amazing range of colors.  For some beautiful photos, check out my articles An Ode to Seed Strain Hellebores and Double Hellebores.  Christmas rose, Helleborus niger, is also regularly found in gardens: for photos see Christmas Rose: The Perfect HelleboreBoth hybrid hellebores and Christmas roses produce leaves and flowers on separate stems (botanists call them acaulescent) so cutting back the leaves has no affect on the flowers.  The questions is when to cut.

If there is a “common” hellebore, then the un-named hybrid hellebore above would be it.  I couldn’t even begin to count the number of flowers on this one plant.  No leaves are visible yet, what you are seeing are bracts on the flower stems.  Photo 3/21/11

 

I do not cut back the leaves of hybrid hellebores in the fall because they are very pretty through the winter.

Hybrid hellebores have attractive leaves that stay green all winter (wintergreen), adding interest to the winter garden, so I leave them on as long as they look nice.  They are not evergreen though so the old leaves should be cut off when they become unsightly in late winter.  It is easiest to do this when the flower buds are still at the soil level and the old leaf stems and new flower stems are not yet intermingled.

This photograph illustrates the new flower stems emerging among the old leaf stems, which will be cut off February 15.  Usually the leaves are standing up causing old and new to mingle, but also providing some protection from cold weather.  Photo 12/31/11

 

In addition to winter interest, I also leave the old leaves on to protect the flower buds should we experience very cold weather in January and early February.  For southeastern Pennsylvania, this could be as low as -5 degrees (-21C).  I cut back my hybrid hellebores around February 15.  The same rules apply for the nine species hellebores that are the parents of hybrid hellebores (see The Sex Lives of Hellebores) should you have them in your garden.

 

This straight species Christmas rose is blooming right now in my garden—it has never bloomed before March in the almost 15 years I have had it.  Notice the lack of leafy bracts on the stem.  Photo 12/31/11

 

Christmas roses have very clean and elegant, blue-green leaves.

Christmas roses have even more beautiful wintergreen leaves.  Although you can cut them back without affecting the flowers (they are acaulescent), my considerations for this hellebore are somewhat different.  The flower stems of hybrid hellebores contain the buds and also leaf-like bracts, which provide a pleasing green backdrop for the blooming flowers (see photo of pink hybrid above).  Christmas rose flower stems have no bracts so if you cut off all the leaves, to me, the plant looks naked when it blooms.  As long as the leaves remain halfway decent, I leave them on until later in the season to serve as a frame for the flowers.  The leaf and flower stems do not intermingle so cutting them later is not a problem.

The buds of bearsfoot hellebore, H. foetidus, emerge from the top of the leaf stem in the fall.  For more photos of this spectacular hellebore, see Hellebores for Fall.  Photo 12/2/10

There are two more wintergreen hellebore species that make their way into hellebore lovers’ gardens: Corsican hellebore, Helleborus argutifolius, and bearsfoot hellebore, Helleborus foetidus.  Botanists call these species caulescent because the flowers are not separate but are on the end of the leaf stem.  You cannot cut off the leaf stem until after the plant has flowered because you will be removing the flower buds.  And if you cut off the individual leaves, you are left with a long, ugly stalk, typically 2-3′, with the flowers at the tip.

I grow Corsican hellebore, H. argutifolius, as much for its gorgeous wintergreen leaves as for its flowers.

In mild winters when the leaves remain attractive, this is not a problem.  It is also usually not a problem for bearsfoot hellebore whose leaves remain pristine during very cold winters.  However, Corsican hellebore leaves are easily damaged, and I often make the decision to sacrifice the flowers and cut the plants back to the ground rather than look at their unsightly leaves while they bloom.  I grow this species equally for its foliage, and new growth springs up very quickly when the old stems are removed.

H. x ericsmithii ‘Winter’s Song’ in my garden right now—much earlier than normal for this species cross.  Notice the leafy bracts surrounding the flowers.  Photo 12/31/11

 

H. x ballardiae ‘Pink Frost’ displaying the pink color inherited from its parent H. lividus.  Photo 3/21/11

That pretty much covers care and maintenance of the hybrid hellebores and the available species hellebores.  However, a large group of gorgeous species crosses are beginning to appear in local gardens (especially if the gardener has been shopping at Carolyn’s Shade Gardens), and I want to let you know how to care for them.  These plants are generally the progeny of Christmas rose crossed with Corsican hellebore and/or Helleborus lividus (not hardy here) to produce elegant outward-facing flowers and silver-marbled leaves often with red highlights and stems.  The most familiar crosses are H. x ericsmithii (‘Silvermoon’, ‘Winter’s Song’), H. x nigercors (‘Honeyhill Joy’, ‘Green Corsican’), and H. x ballardiae (‘Pink Frost’).

 

H. x nigercors ‘Green Corsican’: all the Christmas rose crosses have copious amounts of large, very desirable outward-facing flowers.  Photo 3/21/11

The Christmas rose crosses grow differently than either of the two groups discussed above.  Their leaves are one of their best features, and I cut them back only if they are unsightly.   They do have leaves and flowers on the same stems so you cannot cut the stems back to the base if cutting is necessary.  However, the plants are generally short, 12 to 15″, and produce such an abundance of flowers that cutting off individual leaves from the main stem does not leave an ugly stalk.  In addition, the flowers usually have leafy bracts to frame their beauty.

Our 2010-2011 winter was very hard on hellebore leaves.  However, even though I cut almost all the damaged leaves off these H. x ericsmithii ‘Silvermoon’ plants, they still look beautiful.  Photo 3/24/11

I hope I have answered all your questions about cutting back hellebores.  If not, feel free to seek clarification in a comment.  You are probably wondering what I will do this year when the hellebores are blooming early.  I have decided that discretion is the better part of valor so no leaves will be removed until mid-February.
