Spring Shrub OfferClockwise from upper left: Pink Swamp Azalea, ‘Popcorn’ Snowball Bush, Oakleaf Hydrangea, Coastal Doghobble in winter, Carolina Jessamine, ‘Jet Trail’ Quince.

Because shade gardens are not composed solely of perennials, I offer woody plants—shrubs, trees, and vines—to my customers several times a year.  I want them to have a reliable source for large and healthy specimens, but I also want to make available woody plants for shade that are wonderful but hard-to-find.  I am in the middle of an offer right now, and customers need to let me know if they want to order by Sunday, April 27.  To see the 2014 Spring Shrub Offer, click here.

When I do these offers, I also do a post describing the plants in more detail.  These posts are some of the most popular I have ever written.  In fact, Woody Plants for Shade Part 2 is number four for all time views and Woody Plants for Shade Part 1 is number eight.  If you want to read about all the plants I have recommended, I have included links at the end of this post.  So let’s get to the plants that I am recommending this time, starting with three evergreen shrubs.

.

Buxus microphylla Wintergreen 7-12-10_LSUnfortunately, the only shot I have of ‘Wintergreen’ boxwood shows it in a container, but at least you can see its loose habit and delicate leaves.

‘Wintergreen’ Korean or little leaf boxwood, Buxus microphylla var. koreana,  is a very useful shrub for hedges, edging, achieving a somewhat formal look, and adding evergreen interest to your garden.  At 2 to 4′ tall and 3 to 5′ wide, it doesn’t take up a lot of space.   As an added bonus, ‘Wintergreen’s’ small dark evergreen leaves maintain their green color in the winter unlike most boxwoods, which turn an ugly bronze-yellow.  The loose, rounded habit is easily pruned for use as a hedge.  It grows in part to full shade and is deer and disease resistant.  After this winter it is nice to know that ‘Wintergreen’ is extremely hardy to zone 4.

Leucothoe axillaris 11-7-11_LSThe winter foliage of coastal doghobble.

Coastal doghobble, Leucothoe axillaris, is native to the southeastern U.S., starting just south of Pennsylvania.  It has showy, arching clusters of white, fragrant flowers in May.  The glossy evergreen leaves  have excellent burgundy fall color.  Coastal doghobble looks great even after a hard winter unlike the more commonly available doghobble, L. fontanesiana, which always looks ratty to me.  It is deer resistant and grows 2 to 4′ tall and 3 to 5′ wide in part shade.  Evidently it was given the name doghobble by bear hunters because bears could crash through it but dogs would become entangled.

.

Osmanthus heterophyllus Goshiki 10-26-11_LS‘Goshiki’ osmanthus has a beautiful blend of colors in its leaves and a wonderful fragrance.

‘Goshiki’ variegated holly tea olive, Osmanthus heterophyllus, has dramatic, holly-like evergreen leaves that emerge reddish bronze and change to a lovely blend of cream, gold, and green, lighting up dark corners.  Its delicious fragrance perfumes the garden in November when it blooms.  The prickly foliage repels deer.  My osmanthus came through this winter looking spectacular with no browning.  ‘Goshiki’ grows to 6′ tall and 4′ wide in full sun to full shade.  It received the coveted Pennsylvania Horticultural Society Gold Medal Award as an outstanding shrub for our area.

That covers the evergreens, now for the deciduous shrubs:

.
Chaenomeles x superba 'Jet Trail'‘Jet Trail’ quince, Chaenomeles x superba, is loaded with buds and showy, pure white flowers every March (April this year!) and it only grows to 3′ tall and 3′ wide.  I have profiled it before so for all the details, click here.

.

Hydrangea quercifoliaNative ‘Ellen Huff’ oakleaf hydrangea, Hydrangea quercifolia, has all the four season attributes of my favorite shrub—ornamental bark, beautiful fall color, bold-textured leaves, and gorgeous, long-lasting flowers—plus a vigorous habit and great branching structure.  For more details, click here to read my profile of oakleaf hydrangeas.
.

Jasminum nudiflorumA close up of winter jasmine’s lovely yellow flowers.

.
Jasminum nudiflorumI grow winter jasmine trailing over my terrace walls and enjoy its flowers all winter.

Although Winter jasmine, Jasminum nudiflorum, requires full sun, I am offering it because so many customers have asked for it after seeing my plants trailing off my terraces.  The soft yellow flowers open during warm spells throughout the winter and then prolifically in February and March (April this year) for a very long season.  The graceful, arching stems are dark green providing great winter interest.  The shiny dark green leaves have an unusual delicate texture.  When planted in a flat area, winter jasmine spreads to make an effective ground cover.  It is tough, adaptable, and deer resistant, growing to 3′ tall and 6′ wide in average garden soils.

.
Rhododendron viscosum Betty Cummins 6-6-12_LS (1)Swamp azaleas usually have white flowers, but ‘Betty Cummins’ has lovely deep pink blooms.

‘Betty Cummins’ pink swamp azalea, Rhododendron viscosum, is a rare deep pink flowered form of our native swamp azalea.  Swamp azalea grows wild from Maine to Florida, and this particular form was found in New Jersey.  It blooms in early summer and has a wonderful spicy, clove-like scent.  The deciduous, lustrous deep green leaves turn an attractive orange to maroon in fall.  ‘Betty Cummins’ grows to 6′ tall and 5′ wide in part shade.  It is wet site tolerant and attracts hummingbirds and butterflies.

.

Viburnum plicatum Popcorn 4-6-12_LS (2)‘Popcorn’ Japanese snowball bush is loaded with round white flowers earlier in the season than most other shrubs.

.

Viburnum plicatum Popcorn 4-6-12_LS (5)A close up of ‘Popcorn’s’ flowers: although it looks like an hydrangea, it is actually a viburnum.

‘Popcorn’ Japanese snowball bush, Viburnum plicatum, has 3″ round blooms that open lime green and mature to pure white, putting on a stunning show for a full month in April and May.  The dark leathery green leaves turn burgundy red in fall.  ‘Popcorn’ has a lovely upright, tiered, and compact habit.  It grows to 5 to 8′ tall and 4 to 7′ wide in full sun to part shade, but it tolerates full shade.  It is deer resistant and heat and drought tolerant.

.

Gelsemium sempervirens 'Margarita'‘Margarita’ Carolina jessamine grows on a fence in part shade.  It is native to the southeastern U.S. and has received a Pennsylvania Horticultural Society Gold Medal Award as an outstanding vine for our area.  To see my previous profile, click here.

Letting Go Part 2: Naturalizing Bulbs

Corydalis solidaWhen I stopped trying to keep all my Corydalis solida separate and let the colors hybridize, this is what I got.

In May of 2011, I wrote a post titled Letting Go Part 1: The Lawn.  It is a well-documented discussion of why gardeners should get rid of their lawns and let what lawn remains go “natural”.  At the time I intended to write another article about letting go of garden beds, but time got away from me.  

 .
Galanthus nivalis, Crocus tommasinianusCommon snowdrops, Galanthus nivalis, and snow crocus, C. tommasinianus, naturalized in Charles Cresson’s meadow—a wonderful combination for late winter.

I was inspired to get back to the topic by reading a gorgeous book on bulbs given to me by one of my customers.  Not to digress, but I have the nicest customers who constantly send me articles, bring homemade food, send beautiful cards and letters sometimes hand drawn (one customer is a professional calligrapher), and write complimentary and encouraging emails.  Thanks to you all.

Buried Treasures.

This book was no ordinary gift but a 400 page hardcover book with over 300 color plates.  It is called Buried Treasures and was written by Janis Ruksans.  Ruksans is an internationally famous nurseryman and plant explorer with a mail order nursery specializing in unusual bulbs and located in Latvia.  He has introduced hundreds of bulbs and one of his focuses is Corydalis solida (first photo), which happens to be one of my favorite plants.

Eranthis hyemalis, Corydalis solidaWinter aconite, Eranthis hyemalis, naturalized with corydalis and hybrid hellebores.

Eranthis hyemalisWinter aconite in bloom in February.

As I read his book, I was struck by what he said about naturalizing bulbs:

“There are two different kinds of naturalization.  The first kind occurs when you plant your bulbs so they will look as natural as possible.  The second kind is the real thing, which will happen only if your bulbs start to reproduce by self-sowing.… Some of the most beautiful displays happen in spots where bulbs … have been left to develop naturally.”

As simple as this statement appears, many gardeners have trouble applying this concept to their gardens because it requires letting go.  You are no longer in control of where plants appear and how they combine with each other.  I know because it took me years to embrace it myself.

Scilla mischtschenkoana, Dicentra cucullariaTubergen squill, Scilla mischtschenkoana, on the left and Dutchman’s breeches, Dicentra cucullaria, spread randomly at Carolyn’s Shade Gardens.

However, once I let go of deciding where bulbs (and many perennials) could grow, I believe that my garden reached a whole new level of interest and beauty.  Ruksans’s book inspired me to write this post about the bulbs, including tubers, corms, and other bulb allies, that spread well in my garden.  If you feel inclined to let go, here are some of the bulbs that work the best.

.

Scilla sibericaSiberian squill, Scilla siberica, provides a splash of early brilliant blue and moves all over the garden, even into the lawn.

.

Puschkinia scilloidesStriped-squill, Puschkinia scilloides, is pale blue and spreads beneath my winterhazel.

Mertensia virginicaThere are hardly any beds in my garden that do not sport Virginia bluebells, Mertensia virginica, in early spring.  All I planted was the original clump given to me by a good friend many years ago.

.

Anemone ranunculoides, Mertensia virginicaWood anemones, including Anemone ranunculoides pictured above with Virginia bluebells, have been allowed to form gigantic patches in my woodland.

Anemone nemorosa 'Alba Plena'European wood anemones, A. nemorosa, are a favorite, including ‘Alba Plena’.

.

Chionodoxa forbesiiGlory-of-the-snow, Chionodoxa forbesii, is everywhere even the formal beds by the front door.  It doesn’t take up any “room” because it goes dormant and perennials can be planted right in it.

.

Chionodoxa forbesii 'Pink Giant'‘Pink Giant’ is the pink cultivar of glory-of-the-snow, and it too plants itself wherever it wants.

The most wonderful result of my new relaxed approach came from Corydalis solida, a plant with no real common name.  It is a bulbous corydalis, which comes up very early in spring and dies back shortly after flowering.  Unlike the colorful herbaceous corydalis that never come back due to our hot summers, this corydalis returns year after year without fuss and even self-sows.  Here are a few of its cultivars:

.

Corydalis solida 'Blushing Girl'‘Blushing Girl’ selected by Jans Ruksans.

.

Corydalis solida 'Beth Evans'‘Beth Evans’

All four cultivars are very beautiful in their own right, and at first I kept them separate so they would stay pure.  However, when I let go and nature took its course, the results were amazing.  Now I have a rainbow of corydalis.

Although I have a large garden, this is not a technique limited to big spaces.  Any garden bed full of perennials or any area beneath trees and shrubs is perfect for naturalizing bulbs.  Just give them a free hand after you get them started.
