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.

The 2012 Philadelphia Flower Show

Posted in flower show with tags , , , on March 16, 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 2012 Philadelphia International Flower Show took place last week.  It is the world’s largest indoor flower show and can be a bit intimidating.  My husband and I  find that Friday night is a less crowded time to go especially if you want to photograph the exhibits.  This year’s theme was Hawaii, which was a great choice for me because I attend for the “show” aspects and not to get ideas for my garden.

One of the most interesting parts was the entrance where visitors walked underneath a realistic sounding wave made of screens projected with changing sea life and striped with white flowers evocative of Hawaii.  Created by Valley Forge Flowers of Wayne, PA, it was a full immersion experience as if you were inside the wave:


View of the wave from outside.

There were many scenes of Hawaii (or at least what us easterners think Hawaii looks like), and surf boards were very popular:

 


My husband and I volunteer to staff the exhibit of the Delaware Valley Chapter of the North American Rock Garden Society.  I am not a rock gardener but this organization is worth joining for its lectures and plant sales alone.  Their exhibit was very well received and included a tufa outcropping and hypertufa troughs:

My absolute favorite part of the show is the competitive classes where regional gardeners enter their well grown plants to receive ribbons.  This area, known as the hort court, takes up half the area of the show.  Here are the bulb classes:

 

The competitive classes are filled with well grown individual plants.  Some of them come to the flower show year after year, but I never tire of seeing them:

 

 

 


 

My favorite exhibit was put on by the Pennsylvania Horticulture Society and featured the use of edible plants in an ornamental landscape.  Fruits and vegetables are just as beautiful as any other plants, and this exhibit showed some very innovative uses such as a 10 foot wall of lettuce, a large pergola covered with cherry tomatoes, and a wooden walkway through healthy, gorgeous edible plants:

 

 

I really enjoyed the flower show this year, and, if you couldn’t visit in person, I hope you enjoyed your virtual tour.

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

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

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:

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.
