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:

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'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.

February GBBD: Add to Your Spring Shopping List

“Spring-blooming” hardy cyclamen, Cyclamen coum, sends out its first bud

It is time to walk around your garden again and assess what you need to add to make the end of winter an exciting time in your landscape.  Do you need more early-blooming hellebores to give you a reason to go outside?  Could your garden benefit from flowers that bloom in January and February like hardy cyclamen, snow crocus, or snowdrops to relieve the gray?  Make a list and take photographs so that when you are shopping this spring you know what you need and where it should go.  I know it’s icy outside, but you never know what you might find to end the winter doldrums like the hardy cyclamen (pictured above), which I discovered during my own chilly inventory.

If you need ideas, visit local arboretums and gardens.  I always find a trip to Winterthur, an elegant and intimate public garden in Delaware, highly inspirational and informative.  Starting March 1 when Winterthur opens for spring, the area of the gardens known as the March Bank erupts into bloom with tens of thousands of snowdrops, adonis, winter aconite, snow crocus, early scillas, glory-of-the-snow, spring snowflake, and early daffodils.

Today is Garden Blogger’s Bloom Day for February when gardeners around the world show photos of what’s blooming in their gardens (follow the link to see  photographs from other garden bloggers assembled by Carol at May Dreams Gardens).  Here are a few more highlights from my mid-February stroll through Carolyn’s Shade Gardens:

Very early-blooming double white hellebore, Helleborus x hybridus ‘Mrs. Betty Ranicar’

Bearsfoot hellebore, Helleborus foetidus, was waiting under the ice

Sweetbox, Sarcococca hookeriena var. humilis, prepares to perfume the garden

‘Jacob’ Christmas rose, Helleborus niger ‘Jacob’, began blooming in October and has waited patiently under the snow and ice for a chance to show its flowers again

The lowly Japanese pachysandra, P. terminalis, forms its flowers the previous season adding winter interest to its evergreen leaves

The flower buds of hybrid hellebores, Helleborus x hybridus, wait for the hard-packed snow to melt, in warmer years they would be in bloom now

Some hybrid hellebores are farther along than others

Giant snowdrop, Galanthus elwesii, was the first flower through the snow in 2011 (see Are Snowdrops Thermogenic?) and was also blooming in December

With our near record-breaking snowfall accompanied by generous doses of ice (see The Joys and Sorrows of Snow), I wasn’t planning on participating in February’s Garden Blogger’s Bloom Day.  But when I grabbed my camera and walked around, there was much to be seen.   In addition to the flowers, there was more than enough views of the destruction of the winter by nature and otherwise.

Please let me know in a comment/reply what flowers are blooming in your winter garden.  If you participated in GBBD, please provide a link so my nursery customers can read your post.

Hellebores for Fall

Posted in Fall, Fall Color, hellebores, Shade Perennials with tags , , , , , , , , on December 4, 2010 by Carolyn @ Carolyns Shade Gardens

Hybrid hellebores, the variety of hellebore that most gardeners grow with the big, nodding, showy flowers in beautiful colors, are generally not fall-blooming plants.  They give depth to the fall garden through their evergreen foliage, but they are not thought of for flowers (except a rogue hybrid bloom now and then).  In the mid-Atlantic, they bloom as early as January, but generally start to flower in February.  But there are a few species (as opposed to hybrid) hellebores that flower in fall, and my late fall garden has been much enhanced by their addition.

If I had to choose a favorite hellebore, and I have almost every species and hundreds of hybrids, I would pick the bearsfoot hellebore, Helleborus foetidus.  It wouldn’t be for its charming Latin name: foetidus speaks for itself.  And not for its alternate common name, stinking hellebore, though it doesn’t deserve that name when you have to mangle the leaves to elicit a smell.  Rather I would choose it for its substantial 2′ evergreen presence, like a miniature rhododendron in the garden.  And for the interesting spidery texture of its always pristine dark green leaves.  But mostly for how its chartreuse bell-like buds and flowers perch atop its beautiful foliage from November into May.

Bearsfoot hellebore grows in part to full shade and is the only hellebore that I am aware of that likes slightly moist soil.  That being said, my grove—if they are happy, they spread—received no additional water for the entire summer of 2010 when we had the worst heat and drought I have ever experienced.  Bearsfoot and all my other hellebores came through with flying colors.  I grow all my hellebores with plenty of compost.

Two other fall-blooming hellebores are superior selections from the true Christmas rose, the species Helleborus niger.  Christmas roses are beautiful plants and well worth growing for their outward-facing, starry, pure white flowers and elegant blue-green leaves.  But the straight species is sadly mis-named.  In the mid-Atlantic, it blooms in March  at the earliest when Christmas has long past.  However, the amazing plant breeders at Heuger in Germany who have produced the superior Helleborus Gold Collection have developed two Christmas roses that bloom from November into May.

Christmas rose 'Jacob' at Carolyn's Shade GardensChristmas rose ‘Jacob’

The first, HGC ‘Jacob’, is a compact and refined plant 6 to 8″ tall with graceful, smooth dark green leaves.  It starts blooming in mid-November (it was a little late this year) with copious 2 to 3″ white flowers maturing to rose, and continues to produce buds into May.  The second is HGC ‘Josef Lemper’, a 10″ plant with 3 to 3 1/2″ flowers and larger, lighter green leaves.  It  comes into bloom about two weeks later than ‘Jacob’ and also continues to May.

Christmas roses are a little more finicky than hybrids.  Like most hellebores, they prefer well-drained sites with plenty of organic matter.  But they have a definite preference for the edges of beds in part shade as opposed to sunnier or shadier spots.  My best stand is in an open area shaded by 100′ trees on a steep slope.  I have never found that they needed supplemental lime as the books suggest.

Helleborus dumetorum at Carolyn's Shade GardensHelleborus dumetorum

I am throwing in the final fall-blooming hellebore more for curiosity sake than for its ornamental value.  Over the years, I have collected most of the hellebore species.  I have tried  to get them from more than one source so I could compare them.  The variation is amazing, but no more than hellebore aficionados like Graham Rice will tell you to expect.  One plant I have collected is H. dumetorum—it’s so obscure it doesn’t have a common name.  Its small green flowers and ordinary leaves do not endear it to gardeners.  However, I am including a photograph of one of my plants here because every year it blooms in late October and continues to spring.

For more information on hellebores, I highly recommend noted hellebore expert Graham Rice’s website.  The book The Gardener’s Guide to Growing Hellebores by Graham Rice and Elizabeth Strangman is excellent.  It includes amazing pictures showing the variation within the different species.  I will add both sources permanently to my sidebar so you can always find them.  If you really want all the details about hellebores, try Hellebores by Brian Mathew (Alpine Garden Society).  It is out-of-print but available at horticultural libraries, including the Pennsylvania Horticultural Society.
