On March 3, 7, and 13, my customers and I attended seminars on Snowdrops and Other Winter Interest Plants given by Charles Cresson at his garden, Hedgleigh Spring in Swarthmore, Pennsylvania (US).  Charles is the instructor for the Longwood Gardens certificate course “Hardy Spring and Fall Bulbs” as well as the author of several gardening books.  He is also a frequent lecturer, most recently at the Planting Fields Arboretum on Long Island and Rare Find Nursery in New Jersey for presentations on “Choosing Hardy Camellias for Spring and Fall”.

Charles trained at the Royal Horticultural Society, Wisley, in England and the Kalmthout Arboretum in Belgium, best known for its witch hazel introductions.    He has worked at Meadowbrook Farm, Winterthur, Nemours, and Chanticleer.  His grandfather built the house at Hedgleigh Spring in 1911 and created the garden over the course of 50 years.  Charles has gardened there for  more than 40 years.

Every time we viewed a new snowdrop, no matter how rare, Charles picked two flowers and passed them around so that we could closely examine the markings and experience the fragrance.  He then collected the flowers in a little vase for later comparison.

What a treat Charles’s seminars were.  Even though I attended all three sessions, I learned something new each time and came away with a deep admiration for Charles’s encyclopedic knowledge of plants and the depth of his plant collection, not to mention a wish list of plants for my own gardens.  I also appreciated how each plant was not just deposited in the garden but was carefully incorporated into the overall design.

The seminars began in the front garden viewing the hybrid witch hazel cultivars Hamamelis x intermedia ‘Jelena’ (dark orange) and ‘Moonlight’ (pale yellow) underplanted with snowdrops, winter aconite, and various perennials. Charles does not recommend ‘Moonlight’ because it holds its dead leaves.

It would be hard to name another garden with the wealth of unusual plants that Charles has found and nurtured to perfection over the years.  That being said I thought my customers who were unable to attend the seminars and my worldwide blog readers might like to see what we saw.  I have organized the plants by category below with commentary in the caption where relevant.

We crossed a stone bridge to view the meadow where snow crocus and common and giant snowdrops were massed to be succeeded by daffodils, camassia, and then summer and fall blooming flowers.

A narrow path skirts the pond, which is surrounded on all sides by rock gardens full of unusual plants.

The Bulbs

We saw so many rare and unusual bulbs that I can only include a sampling here.

A rare pale yellow form of winter aconite, Eranthis hyemalis

The exquisite buds of the species crocus C. imperati ‘De Jager’

Masses of the rodent resistant and very early blooming snow crocus, Crocus tommasinianus ‘Whitewell Purple’, shadowed by a magnificent Japanese maple.

The very early blooming daffodil Narcissus ‘Rijnveld’s Early Sensation’

A very good form of winter blooming hardy cyclamen, Cyclamen coum

The reticulate iris I. histrioides ‘George’

There were large patches of spring snowflake, Leucojum vernum, throughout the garden.

The flower of spring snowflake, Leucojum vernum

We were privileged to see this semi-double form of spring snowflake,  which Charles has named  Leucojum vernum ‘Gertrude Wister’ and registered with the Dutch bulb authority.

The Snowdrops

If you read my blog, you know what a galanthophile I am so with supreme effort I have limited myself to just a few of the many snowdrops we saw.

Clockwise from upper left: G. elwesii var. monostichus, G. ikariae, ‘Jaquenetta’, ‘Straffan’, G. plicatus subsp. byzantinus, ‘Dionysus’

Galanthus ‘Brenda Troyle’, confused in the trade but still quite lovely

Galanthus plicatus subsp. byzantinus Cresson GardenThe elegant pleated leaves and plump flowers of Galanthus plicatus subsp. byzantinus

The beautiful shiny green leaves of Galanthus woronowii

There were drifts of Galanthus ‘S. Arnott’, called the ‘desert island snowdrop’ because it is the one cultivar many galanthophiles would choose if they were limited to one.

The Perennials

A very rare perennial for shade Amur adonis, A. amurensis ‘Fukuju Kai’

Helleborus niger double form Cresson gardenA semi-double form of Christmas rose, Helleborus niger, which I have only seen at Hedgleigh Spring

The Algerian iris, I. unguicularis, blooming in early March with a beautiful fragrance

The Shrubs

Koehne holly, Ilex x koehneana, looking as fresh and beautiful as it did in the fall

Camellia japonica ‘Spring’s Promise’ was one of several very early spring-blooming camellias that we saw.

Grape holly, Mahonia x media ‘Arthur Menzies’

A highlight for me were the buds on this paperbush, Edgeworthia chrysantha ‘Snow Cream’, which look like the tassels on Victorian cushions

Hybrid witch hazels, Hamamelis x intermedia ‘Jelena’ and ‘Moonlight’

I hope you have enjoyed your virtual seminar.  Please let me know in a comment/reply what your favorite winter interest plant is.

Red-flowered Camellia japonica (introduction in process)

In my previous article, Fall-blooming Camellias Part 1, I showed you my camellias and provided some background on the development of these remarkable plants.   Here I want to convey the astonishing variety of cultivars available for your fall  garden.

On December 2 (before the freeze), I was privileged to visit the camellia collection of Swarthmore, PA, horticulturalist Charles Cresson who grows over 60 varieties.  Charles not only showed me around his gardens, but helped me stage the photographs—thanks Charles.  Here are some of the incredible specimens I saw.

Red-flowered Camellia japonica (introduction in process)

Of all the camellias I saw during my visit, and there were many more than appear here, you can probably tell that the red-flowered camellia in the photographs above and at the top was my favorite.  From its plentiful plump buds to its robust red flowers with bright yellow stamens to its dazzling dark evergreen leaves to its lush and  luxurious habit, it is outstanding.  It is a straight C. japonica  species collected by the Morris Arboretum in 1984 on an island in Korea.   The island is the most northern range of this species. Although technically a spring bloomer, it also flowers in fall.  Charles hopes to introduce it for sale soon.

For more information on Ackerman  hybrid camellias, read William Ackerman’s article “Camellias for Cold Climates”.  For a wonderful selection of camellias from a nursery that hybridizes them, visit the Camellia Forest Nursery website.  Camellia Forest is located in Chapel Hill, NC.

Fall-blooming Camellias Part 1

Camellia x (Unknown Ackerman Hybrid)

From 1992 to 1997, I earned two Certificates in Ornamental Plants from Longwood Gardens.  Of all the horticultural classes I have taken, these are the best, and I still use the course books as my primary plant reference.  As I worked my way through the 18 required courses from bulbs to perennials to shrubs to vines, I made a mental life list of the plants I wanted in my garden.  Some I added immediately, but others were stored away to be added in the future as I discovered them randomly at the nurseries I visited.  This year, fall-blooming hardy camellias rose to the top of the list.

Actually, my flirtation with fall-blooming camellias began about 10 years ago during a tour of the Morris Arboretum when I was given a tiny seedling of their Camellia oleifera (two photos above), which was a cutting of the original and famous ‘Lu Shan Snow’ at the U.S. National Arboretum.  It has grown into quite a large shrub with beautiful cinnamon-colored bark, glossy dark evergreen leaves, and copious single white flowers from late October into December.  It is also completely cold hardy, but not resistant to deer who dined on it voraciously.  There were to be no more camellias in my future until I freed up a space for them inside my deer fence.

This spring I removed several large and ailing boxwoods from a sheltered spot by my patio and simultaneously found a source for specimen camellias—it was a “perfect storm” for my venture into the fall-blooming camellia world.

fall-blooming camellia 'Elaine Lee' at Carolyn's Shade GardensCamellia x ‘Elaine Lee’

I purchased three gorgeous plants.  The first, Camellia x ‘Elaine Lee’ (photos above and bottom), has semi-double white flowers that bloom from November sporadically through January.  It has an upright form with an average growth rate to 5 feet.  The second, Camellia x ‘Winter’s Darling’ (photo below), has miniature, anemone-form deep cerise pink flowers that start at the end of October and continue through December.  It has a moderately upright habit and grows slowly to 3 to 5 feet.  The third is an Ackerman hybrid camellia (photos top, above, and bottom), but I am not sure which cultivar.  It has semi-double deep pink flowers.  All three have beautiful glossy dark evergreen leaves.

Camellia x ‘Winter’s Darling’

These hardy fall-blooming camellias, along with many others, were developed by Dr. William Ackerman at the U.S. National Arboretum by crossing C. oleifera with more ornamental forms to produce superior plants.  They are truly hardy in the mid-Atlantic, but should be sited to protect them from winter sun and our winter winds, which come from the northwest, and mulched in winter.  They prefer a well-drained site in part shade.

For more information on Dr. Ackerman’s hybrids, read his article “Camellias for Cold Climates”.  For more information on camellias, go to the International Camellia Society’s website.  Stay tuned for my next camellia post which will highlight photographs from my recent visit to a private collection of over 60 camellias.

The U.S. National Arboretum, which is part of the USDA, is the source for many of the best plant breeding programs in the U.S.  It also maintains national collections of plants.  The arboretum is currently planning to deaccession its Azalea and Boxwood Collections as well as part of the Perennial Collection.  In the case of the Azalea Collection, although budget concerns were mentioned, one of the reasons given was that it attracted too many visitors. I may be wrong, but I can’t imagine this happening in the U.K.  If you would like to find out more about this amazing azalea collection and the efforts to save it, go to the Save the Azaleas website.
