Hellebores are in their prime.  Here is a claret colored hybrid at sunrise.  We have a wonderful selection of hellebores for sale right now.

Apparently winter is over, although nothing could surprise me in the weather department this year.  Last weekend when Kelly Norris, Director of Horticulture at the Greater Des Moines Botanical Garden, visited my gardens, the tour consisted of me pointing and saying “if it were really spring, you would be seeing….”  Now the garden is bursting, please come back Kelly :-)!

Nursery News:  Email for an appointment to shop for many of the plants featured in this post or come on Saturday between 10 am and 3 pm when customers are picking up their edgeworthias, just email me a time.  Our second sale featuring hellebores and native plants is Saturday, April 15, from 10 am to 3 pm (checks and cash only).  Customers will get details in an email.  For announcements of spring 2017 events, please sign up for our customer email list by sending your full name and phone number to carolynsshadegardens@verizon.net.  Let us know if you are local or mail order only.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

Bearsfoot hellebore, H. foetidus, stood up particularly well during the extreme heating and cooling and heavy snow that March threw at it.  Lots of customers have been asking for these, and we have more in stock.

.

‘Goldheart’ old-fashioned bleeding-heart seems to appear overnight.  It turns into a majestic plant with gold leaves and pink flowers, a combination I have grown to love.

.

.‘Diana Clare’ pulmonaria’s large blue flowers look spectacular with its emerging silver leaves.

.

Once you have a couple of varieties of pulmonarias, they start to cross and every one is beautiful.

.

The lovely, pale yellow flowers of Anemone x seemanii were produced by a cross between A. ranunculoides and A. nemorosa, European wood anemones.  Very rare and available at Carolyn’s Shade Gardens for the first time this year!

.

Our native double bloodroot, Sanguinaria ‘Mulptiplex’, is my all time favorite flower.  It seems to prefer the rocky slope in my woodland, and I often see the single form on road embankments.  We take special orders for this plant.

.

Our display gardens have about forty types of epimediums, and their flowers are popping out of the ground.  Here, the orange-flowered E. x warleyense.  We will be selling this epimedium along with ‘Roseum’, ‘Niveum’, ‘Lilafee’, E. grandiflorum, and the rarer ‘Yubae’ (Rose Queen) and ‘Pierre’s Purple’.

.

Epimedium pinnatum subsp. colchicum

One of the first plants I ever planted and still a favorite: Dutchman’s breeches, Dicentra cucullaria.  Available this spring.

.

There are lots of dogtooth violets in our woodland and they have even crossed and produced some stunning new forms.  This is the European Erythronium dens-canis.  Its flowers are gorgeous but sparse.  We sell the US native ‘Pagoda’, a vigorous plant with many yellow flowers just starting to open.

.

Everything is so late this year!  Native moss phlox ‘Emerald Blue’ is just starting to open its flowers.  Moss phlox makes a great, evergreen groundcover in sun to part shade in dry areas.  Ask us to point out our amazing stand of the white-flowered form ‘Nice n’ White’.  We also sell purple, crimson, and a new, more compact cultivar called ‘Emerald Pink’ that looks like a miniature boxwood.

.

‘Shell Pink’ lamium bursts into bloom now but then continues to flower until December.  It is the only lamium that produces flowers for three seasons.  Its leaves are also semi-evergreen so the ground is never bare.  It is not invasive and should not be confused with the yellow-flowered lamiastrum.

.

Anemone ranunculoides, a parent of A. x seemanii shown earlier, is a bolder color and faster spreader.  We also sell ‘Bractiata’, ‘Vestal’, ‘Alba Plena’, and ‘Wyatt’s Pink’ European wood anemones.

.

Now we get to one of my favorite plants, Corydalis solida, which you will see all over my garden in a rainbow of colors.  Its common name is fumewort, but I never hear anyone call it that.  The photo above shows the varieties that I sell: ‘George P. Baker’ in the foreground, ‘Purple Bird’ in the center, followed by ‘Beth Evans’, and ‘White Knight’ at the very back.

.

‘White Knight’ is new this year and is a stunning form, densely packed with pure white flowers.

.

If you let Corydalis solida self-sow in your garden, you will get some gorgeous un-named forms like the blue above.  Unlike other brightly colored corydalis, fumewort comes back reliably every year.  It goes dormant after it flowers but reappears bigger and better the next spring.

.

.

.

.

A mixture in my woodland

If you are local and want to get a jump on the April 15 open house sale, we are around today, tomorrow, and all weekend.  Just email for an appointment.  Or come Saturday between 10 am and 3 pm when customers are picking up their edgworthias—let me know an approximate time.

2013 Winter Interest Plants

Posted in garden to visit, hellebores, Shade Gardening, snowdrops, winter, winter interest with tags , , , , , , , , , , , , , , , , , , , , , , , , , , , , on March 4, 2013 by Carolyn @ Carolyns Shade Gardens

Galanthus 'Brenda Troyle'Galanthus ‘Brenda Troyle’ is one of the most robust and fragrant snowdrops in the Cresson garden.

This may be my last post that focuses on snowdrops, and I am sure some readers will rejoice.  I am aware that many gardeners do not share (or understand) my obsession.  However, I want to show photos from the recent Winter Interest Plants Seminars hosted by Charles Cresson for my nursery customers. 

Before I get to that though, I have to tell you about the snowdrop event this weekend at Winterthur, the fabulous garden in Delaware, US.  On Saturday, March 9, at 11 am, Alan Street, the world famous snowdrop expert from Avon Bulbs in England, is presenting the annual Bank to Bend Lecture on snowdrops.  Carolyn’s Shade Gardens will be one of two nurseries selling snowdrops and other winter interest plants at Winterthur.  I hope to see you there.  Here are the details:


winterthur

Join plantsman and snowdrop expert Alan Street of the renowned nursery Avon Bulbs as he offers insight into these precious flowers, sharing how they have become a worldwide phenomenon and how Avon Bulbs brings them to market. Registration includes tours of the March Bank display and access to specialist nurseries selling snowdrops and other winter interest plants. $20 non-members; $10 members.

Call 800.448.3883 to register or find out more.

Bank to Bend includes free admission to the garden, tours of the March Bank and access to specialist nurseries Black Hog Horticulture and Carolyn’s Shade Garden to purchase rare and unusual bulbs and other winter interest plants.

Cresson Winter Interest SeminarCharles Cresson talks about his witch hazels, winter aconite, and snowdrops with some die hard winter interest gardeners.

This is the third year that nationally known horticulturalist Charles Cresson has hosted my customers in his Swarthmore, Pennsylvania, garden to view and discuss winter interest plants.  Every year we see different plants, depending on the weather, but every year the group is just as enthusiastic despite the weather.  This year, February (and all winter really) has been cold and dismal, and the seminar days were no exception, but the attendees were enthusiastic and full of questions for Charles.

Cresson Winter Interest SeminarsCharles demonstrates how he protects important plants with plastic boxes if the weather is going to be unseasonably cold.

Plants are “late” to come out this year because it has been so cold.  The emergence of winter interest plants like perennials and bulbs is dependent more on the soil temperature than on the date.  If the soil warms up early, as it did in 2012 when we had no winter, many plants will bloom early.  This year it has been cold and gray, and many plants have yet to bloom or emerge.  Yet, such is the magic of Charles’s garden that there was a lot to see.  Here are some of the highlights in the order in which we saw them:

Narcissus 'Rijnveld's Early Sensation'After seeing this daffodil for many years blooming in Charles’s garden in February, I finally added it to mine this year.  It is called Narcissus ‘Rijnveld’s Early Sensation’.

.

Eratnhis hyemalis (pale yellow form)A rare pale yellow form of winter aconite, Eranthus hyemalis.

.

Crocus tommasinianusThe snow crocus, C. tommasinianus, is my favorite crocus because it blooms now with the snowdrops and multiplies rapidly.

.

Crocus tommasinianus 'Ruby Giant'‘Ruby Giant’ snow crocus is a deeper purple.

.

Crocus tommasinianus 'Taplow Ruby'‘Taplow Ruby’ snow crocus

.

Galanthus 'Atkinsii'Galanthus ‘Atkinsii’ is an old-fashioned and reliable snowdrop that should be part of any collection.

.

Galanthus 'Atkinsii' & Arum italicum 'Pictum'One of my favorite combinations, ‘Atkinsii’ with Italian arum, A. italicum ‘Pictum’.

.

Helleborus x ballardiae 'Pink Frost' with Cotoneaster salicifolius 'Henryi'The leaves of ‘Pink Frost’ hellebore, H. x ballardiae ‘Pink Frost’, pair beautifully with this rare cotoneaster, C. salicifolius ‘Henryi’.

.

Helleborus foetidus & Helleborus x ballardiae 'Pink Frost'‘Pink Frost’ again with bearsfoot hellebore, H. foetidus, in another winning combination.

.

Helleborus x ericsmithii 'Winter's Song'‘Winter’s Song’ hellebore, H. x ericsmithii ‘Winter’s Song’ is very early blooming so it was fully out on this cold February day.

.

Helleborus x 'Ivory Prince'‘Ivory Prince’ hellebore was just starting to open.

.

Iris unguicularis subsp. cretensisThis subspecies is an especially dark colored version of the winter-blooming Algerian iris, Iris unguicularis subsp. cretensis.

.

Galanthus 'Mighty Atom'

Galanthus ‘Mighty Atom’ has one of the best presentations of any snowdrop.

.

Galanthus rizehensisGalanthus rizehensis is a rare and desirable snowdrop species.

.

Galanthus 'Standing Tall'Charles’s newly introduced snowdrop ‘Standing Tall’ continues to stand up to whatever the weather throws at it.  If you didn’t know better you would think it was a daffodil.

.

Galanthus 'Beth Chatto' ‘Beth Chatto’

.

Galanthus 'Godfrey Owen'Charles and I both acquired six-petaled ‘Godfrey Owen’ last year but his was not felled by snow and ice.

.

Galanthus 'Godfrey Owen'‘Godfrey Owen’

.

Galanthus 'Godfrey Owen'The inner segments of ‘Godfrey Owen’ are extraordinary too.  This photo represents to me what galanthophiles are all about.

.

I know the participants enjoyed themselves because even after an hour and a half in the cold, they were still asking Charles questions.  I hope my readers have gotten some vicarious enjoyment.

Species Hellebores for 2012

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

‘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.

Fragrant hellebore (right) with ‘Blue Lady’ hybrid hellebore



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

Posted in bulbs for shade, Camellias, evergreen, garden to visit, hellebores, landscape design, Shade Perennials, Shade Shrubs, snowdrops, winter, winter interest with tags , , , , , , , , , , , , , , , , , on February 29, 2012 by Carolyn @ Carolyns Shade Gardens

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.

January GBBD: Hellebores on Parade

Posted in Camellias, evergreen, Garden Blogger's Bloom Day, garden to visit, hellebores, Shade Perennials, Shade Shrubs, snowdrops, winter, winter interest with tags , , , , , , , , , , , , , , , , , on January 11, 2012 by Carolyn @ Carolyns Shade Gardens

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

‘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

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.

December GBBD: Past Prime

Posted in Camellias, Fall Color, Garden Blogger's Bloom Day, hellebores, Shade Perennials, Shade Shrubs, snowdrops, winter interest with tags , , , , , , , , , , , on December 13, 2011 by Carolyn @ Carolyns Shade Gardens

Every year I make a Christmas wreath using all natural materials from my property.

It is the middle of the month and time to participate in Garden Blogger’s Bloom Day hosted by May Dreams Gardens 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.  I also hope that my customers will get some ideas for plants to add to their own gardens to extend their season well into late fall.

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


I used berries from this native winterberry holly, Ilex verticillata ‘Red Sprite’, to make the wreath.  On December 7, the robins came and cleaned off all the berries.

Last month was still prime time in my gardens, but now with hard frosts and generally colder weather, my gardens are past their prime.  The show goes on though with the focus shifted from the garden as a whole to individual plants peaking between November 15 and December 15 (I do not take all my photos on December 15).  This means that they bloom now (or are still blooming), have ornamental fruit, or feature exceptional foliage or fall color during this period.

Let’s start with flowers:

The large and vigorous fall-blooming snowdrop ‘Potter’s Prelude’ is in full bloom through this entire period.  Mine is surrounded by the marbled purple foliage of ‘Frosted Violet’ coralbells, Heuchera villosa ‘Frosted Violet’.  For more on fall-blooming snowdrops, click here.

Over the years, I have planted hundreds of giant snowdrops, Galanthus elwesii, and in the process have acquired plants that bloom in the fall instead of January when this species normally blooms.

I am always raving about the long bloom time of  ‘Shell Pink’ lamium so I thought you might like to see a photo of it in full bloom in December.  For more on lamium as a wintergreen groundcover, click here.

The buds on my paperbush, Edgeworthia chrysantha, have gotten large enough to show their beautiful silvery color and will remain ornamental until they start to open in March.

‘Zebrina’ hollyhock mallow, Malva sylvestris ‘Zebrina’, does not seem to be bothered by hard frosts.

Hellebores are one of the primary contributors to flowers during the winter months:

The spent flower heads of ‘Josef Lemper’ Christmas rose, Helleborus niger ‘Josef Lemper’, which has been blooming since early October, seem more ornamental when everything else has gone by.  Buds are forming at the base for the next wave of bloom.

Since November 15, another Helleborus dumetorum (no common name) has put out fresh foliage and covered itself in flowers.

The lighter chartreuse buds are forming on bearsfoot hellebore, H. foetidus, which will remain ornamental through May.

‘Jacob’ Christmas rose, Helleborus niger ‘Jacob’, is covered with buds just starting to open.

This photo might not look very exciting, but I am thrilled to see buds on my rare double Christmas rose, Helleborus niger ‘Double Fantasy’.  In all my years of collecting hellebores, I have only seen a double Christmas rose once in a garden.  Now I will be offering blooming plants to my customers in my 2012 snowdrop catalogue.

This is what ‘Double Fantasy’ will look like when it’s open.

My fall-blooming camellias are a mainstay of my garden right now.  The first three pictured below are Ackerman hybrids, which I profiled in Fall-Blooming Camellias Part 1:

This is the last flower on Camellia x ‘Winter’s Darling’.

Camellia x ‘Elaine Lee’ still has a few buds left .

Camellia x ‘Winter’s Joy’ has been flowering since October and is still covered with buds.

Fall-blooming Camellia oleifera is no longer covered with flowers but still continues to produce blooms when the weather warms up.

I was very lucky to receive as a gift this fully hardy, red-flowered Camellia japonica from Korea.  It has not yet been introduced for sale.  For more information on and photos of camellias, including this one, click here and here.

If you are just in it for flowers, then you can stop here because the last few plants rely on leaves to make their contribution.  However, foliage is very important for filling out the late fall garden, and I wanted to give you a few ideas:

Although they have dropped now, dwarf fothergilla, F. gardenii, holds its gorgeous fall leaves way beyond November 15.  For more information on this outstanding native shrub, click here.

Another woody with late fall color is ‘Shishigashira’ Japanese maple, Acer palmatum ‘Shishigashira’.

‘Magic Carpet’ spiraea, S. japonica ‘Magic Carpet’, is still displaying some of its gorgeous fall color right now.

‘Albury Purple’ St. John’s wort, Hypericum androsaemum ‘Albury Purple’, remains fully clothed in plum-colored foliage.

This is the first year that I have grown ‘Cool Splash’ southern bush honeysuckle, Lonicera sessifolia ‘Cool Splash’, but I am amazed to find that it looks like this right now.  For more information on this great native shrub, click here.

I have over 20 kinds of pulmonaria or lungwort in my garden providing me with beautiful flowers from February to April, but I appreciate them almost as much for their pristine foliage through early winter.

‘Diana Clare’ lungwort, Pulmonaria ‘Diana Clare’

Both native ‘Bronze Wave’ coralbells, Heuchera villosa ‘Bronze Wave’, and fall-blooming hardy cyclamen, C. herifolium, will look like this all winter.

My post, More Flowering Wintergreen Ground Covers of Shade, included several photos of Italian arum cultivars, which are great winter interest plants.  I won’t repeat those plants here but show you a seedling that appeared among my arum.  The leaves are more pointy and narrow than the species and the markings go beyond veining to cover the leaf.

Enjoy the last few days of fall,  Carolyn
