The New Year was preceded by several days of balmy temperatures.  Christmas week was warm enough to provide a lot of unexpected color in the Washington area.  There were several sightings of Chaenomeles, Chimonanthus praecox ‘Lutea’, Corydalis ochroleuca, Erica cultivars, Forsythia, Hamamelis, Helleborus × hybridus, H. niger, H. foetidus, Jasminium nudiflorum, Lonicera fragrantissima, Mahonia bealei, Phlox subulata, Prunus subhirtella ‘Autumnalis’, daffodils, dandelions and pansies from members living on all points of the compass—not just those of us south of I-95.  In order to conserve space, I have not repeated plant names but have repeated the genus when a species or cultivar name was furnished.  In the several years that I have been compiling a census, never has the distribution of identical blooming plants been so wide.  In most previous censuses, the largest list of blooms was in Bob and Audrey Faden’s warm, sunny, and large garden.  The Faden garden still had an enormous number of blooms, but many of those plants were sighted in other gardens the week before.  It is interesting that the Faden garden did not add many new blooms.  Surely they cannot have maximized their winter gardens! 

Jim Dronenburg, in almost West Virginia, with a brick courtyard garden that creates a much warmer environment and a sun-drenched three-acre garden, was the first to report.  Other gardeners, listed below, have planted to enhance the local environment.  And some people are just plain lucky—they have deciduous shade on the south side of their house, but they were clever enough to plant to that strength.  In spite of my fondness for Jim’s warm courtyard garden, the list below only includes one courtyard resident—the rose.

Jim Dronenburg lists these plants as blooming 1/1/07:

Rosa ‘Tausendschoen’ – two little also-ran blooms (in Jim’s enclosed courtyard garden)

Salix – Japanese tree pussy willow

Viola odorata, probably ‘Queen Charlotte’

Warren Schor, who has a most interesting bulb collection, added:

I asked Warren about the placement of the Daphne odora. It was not blooming in the Faden garden nor in mine, both warmer gardens. Clever Warren had planted the Daphne next to a south facing wall, protected in the summer by a deciduous tree.

Alice Nicolson’s list was sent on January 2. She has provided some description of the local environment, helpful to those who might want to increase their own winter garden. Alice seems to have the largest collection of Galanthus in the survey. Simplifying a mystical grouping of plants, Bob and Audrey Faden said their fall, winter and spring blooming Galanthus were in bloom – a first for them. As they got all of the plants from Alice, they suggested I use Alice’s listing.

It was raining and just plain wet and nasty in Alexandria on 1/1, so Bob, Audrey and I postponed the trip through their garden until the next day. In between the rain drops, Bob had made a good list:

Euphorbia nicaeensis ‘Dolce Vita’ Audrey states that the plant was received as listed but is probably not that.

Bobbie Diebold added:

Jim McKenney reported blooms on:

Viola ‘Feline’ (this is a Parma violet sport); I can smell Viola odorata in the garden but I can’t find the flowers.

Anne Mazaitis made a list 1/1 but was unable to post until 1/7. In spite of a census by several gardeners, she had blooms not duplicated in other gardens:

At the end of this list, I have little to add but I do have something.  Cheiranthus ‘Charity Scarlet’ and Erysimum ‘Yellow Bird’ provided nice color in the garden.  For the first time I spotted New Year’s Day blooms on  Helleborus odorus and double maroon H. × hybridus ‘Party Dress Hybrid’ but the most important discovery is the re-appearance of a plant that has not yet bloomed during the  six years it has been in my garden—Helleborus vesicarius.  I do no know that it will ever bloom as it misses its Mediterranean climate and spends so little time above ground that it is astonishing that it has doubled in size.  It now has two stems. This is not a giant leap forward but winter gardening provides small pleasures – not the great, gaudy, exuberant blooms of spring, summer and fall.                  Dixie Hougen

In the on-line version there are some images provided by Jim Dronenburg and Dan Weil of plants blooming in their Knoxville, Maryland garden.

1.      Meeting was called to order by President Alma Kasulaitis.

2.      The Treasurer’s Report and the proposed budget for 2007 were presented by Margot Ellis. Our current assets (checking and CD) as of November 4, 2006 were $10,276.50. Questions regarding our current assets or the budget for 2007 may be directed to Margot Ellis.

3.      Locations for future meetings: We are currently exploring new venues in addition to those we have used in the past. Our goal is to spread the meetings around the area geographically so that the members aren’t necessarily always being forced to drive long distances to attend a meeting. Peter Jones points out that the Walter Reed Recreational Center in Arlington is now available for such meetings and would be free (always a plus!).  The board would welcome additional suggestions from the membership.  In addition to our local meetings, there was some discussion of future field trips, their costs, and the benefits of attracting potential new members.

4.      Ways and Means Committee: Because the complexity of handling plant sales, bus trips, etc. adds a substantial burden to the task of planning any of these events, the board is considering establishing a Ways and Means Committee. This committee would work in conjunction with the Program, Education and Outreach Committee and focus on upcoming events.

5.      Plant Exchange:  There was a discussion regarding the rules for participation in the semi-annual plant exchanges. Although the rules are fairly simple, it seems that they are often disregarded. For example, it was pointed out that we have long had a baseline requirement of six plants being contributed to the exchange. Other standards include current (paid-up) membership in the organization, one membership equals one participant (although plotting and consultation between household members is certainly xxx), and a focus on outdoor plants (sharing non-hardy plants growing like Topsy is a side-bar to the Real Event). For the convenience of the membership, a complete list of the rules will accompany the announcement of time and place for an upcoming exchange.

6.      Newsletter circulation: a brief discussion was held regarding coordination between the current active membership list and distribution of the newsletter.

7.      Budget for PVC – NARGS: Establishing an annual budget has been discussed several times and actually going forward with this would be a sound financial move. This has not yet been completed.

8.      Attracting Members: How and where to find and attract new members is a perennial topic in virtually all organizations. During this discussion it was pointed out that even the parent organization (NARGS) has been challenged to attract new participants to keep the organization vibrant and active.  Our own local chapter must consider this as well. Gaining members is one important goal but there is also the need to engage our members in the actual running of the organization.

9.      Memorial for George Phair: Dixie Hougen will be exploring the choice of a location and the actual memorial for George.

10.  Our Next Meeting: Will be January 27^th at the U.S. Botanic Garden production facility: you must notify Betty Spar in advance if you intend to attend this meeting. .bspar@aoc.gov

The meeting was adjourned

THE EXPANDING GARDEN

On Wednesday, Dec. 27, 2006 the first spring crocus opened in the sand bed on the YMCA that is dominated by exuberant yuccas.  This is by far the earliest that any spring blooming crocus has opened for us.  What also made it so unusual was that only a few feet away from the tiny yellow blossoms of Crocus korolkowii ‘Lucky Number’ were the much larger lilac flowers of the fall flowering C. laevigatus, which had never flowered so well or so long before.  How much longer the very early spring and late fall flowering will continue to overlap remains to be seen, but it has just carried on into 2007.

Other fall-flowering plants also have lingered longer than usual.  The climbing aster, A. carolinianus, had some open flowers on January 1, as did one plant of New England aster (A. novae-angliae).  The camellia hybrids, C. ‘Winter’s Star’, C. ‘Snow Flurry’ and C. ‘Winter’s Beauty’ also continued into the New Year, with the last – probably wrongly named, according to the book Growing Camellias in Cold Climates, by William Ackerman, because our plant has snow-white, instead of shell-pink, double flowers – only recently peaking.  On Jan. 1 these camellias were joined by C. ‘Spring Promise,’ a spring-flowering C. japonica that often has its first, large, double, red flowers as early as November and reblooms during warm spells in the winter.  Why it failed to flower this past fall is a mystery.

The earliest flowering daffodils, ‘Rijnveld’s Early Sensation’, started blooming before the New Year, which is a first for us.  The bulbs are surrounded by numerous plants of Viola rupestris ‘Rosea’, with small, rose-purple flowers.  Many other daffodils have leaves coming up, but none has buds.  The only other bulbous plants blooming before the New Year were the fall-flowering clones of Galanthus elwesii var. monostictus, which we were originally given by Alice Nicolson.  On Jan. 1, spring-flowering Galanthus elwesii subsp. elwesii opened, which is the first time that the fall- and spring-flowering forms of this species have bloomed together.

We always look forward to the winter-flowering shrubs.  Some of them, like odorless, winter jasmine (Jasminum nudiflorum) and fragrant Lonicera fragrantissima and Viburnum farreri ‘Nanum,’ started weeks ago and are in full flower.  Some others, such as the Lonicera ×purpusii ‘Winter Beauty’, Mahonia bealei and M. japonica had barely started before the New Year.  We were especially pleased to get flowers on M. japonica for the first time.  The plant very closely resembles M. bealei in foliage and habit, so even though we purchased it as ‘real M. japonica’ at a winter study weekend several years ago, we remained skeptical about its true identity.  In flower M. japonica is reported to have longer, looser inflorescences with flowers on longer stalks than in M. bealei.  Our plant really does show those features, so I am more of a believer.  M. japonica is supposed to seldom set fruit, which would set it apart from M. bealei.  Time will tell.

Another new bloomer for us is the hybrid witch hazel Hamamelis ×intermedia ‘Feuerzauber’, which we purchased last year.  The coppery red flowers on this one-foot high plant were unfortunately a bit too low to the ground for us to report on their fragrance.

Sadly two plants are missing from our usual early blooming list.  Our large wintersweet (Chimonanthus praecox) outside the YMCA pool died in 2005.  Its replacement is growing on the north, instead of the west, side of the YMCA building, so it gets no winter sun, and even the unusually warm December temperatures have left its buds only swollen, perhaps still a week or two away from opening.   Even sadder, the death last summer of the Japanese apricot (Prunus mume) in Simpson Park has deprived us and the neighborhood of my favorite winter-flowering tree, with its double-pink, very fragrant flowers.  A seedling of it, which we kept way too long in a pot and only planted out in fall 2005, now grows on the YMCA, but it is still a few years away from flowering.  A sister seedling, directly planted in the ground outside the Smithsonian’s research greenhouses in Suitland, MD a few years ago by greenhouse manager Mike Bordelon, was blooming on Dec. 28 with flowers very similar to those of its deceased parent, so we are hopeful that our plant will have the same kind of blossoms. 

In all we had about 40 species, varieties and cultivars in flower on January 1.  Certainly that exceeds any other year for which we have records or recollections.  Is it global warming or just part of a short term cycle?  Who can say?  But from now on, Zone 8 plants will not be automatically excluded from consideration; they will just be thought of as special challenges.

Robert Faden    3 January 2007

Dick and Judith Knott Tyler have owned and operated Pine Knot Farms since 1982, two years after they returned to the US after living in Canada for eight years. The land where the nursery is located is part of a farm that has been in Judith’s family for six generations. When the Tylers returned to Virginia they were severely garden deprived and began producing plants to fill the borders that were being created before they finished building their house. Since their gardens are located in an eastern mixed deciduous forest, the primary focus soon became plants that would thrive in shade. Hellebores soon became a focus and after a few years the collection became an obsession.

Dick, who was a building contractor for twenty years, is primarily responsible for the hardscapes and soil preparation. He has created several garden structures and is planning a gazebo/summerhouse in the newest area under construction. Being gifted with a natural talent to see the underlying structures, he is the chief electrician cum plumber cum carpenter, mechanic and whatever else needs attention. A university course in Geology may have sparked his interest in stone, which is visible at the garden in the form of walls, steps and pathways. Dick began studying photography in the mid 1970’s and is responsible for all the slides and photographs used for talks, website, and publications.

Judith studied art and was interested constructing mixed media collage/sculpture before their children were born. She feels that some of this energy has been channeled into creating gardens, since the forms and textures of plants can be layered to create a living sculpture that changes with the seasons. She is also responsible for the metal accessories that adorn several of the borders. Her early love of words and former literary aspirations has found an outlet in writing the Pine Knot Farms catalogue, articles and editing the website.

Both partners fell under the intoxicating influence of the genus Helleborus, began breeding the plants and their lives have never been the same. Each winter is devoted to travel and study of the genus. Travels have taken them throughout the US, UK, Europe and The Balkans searching for hellebores to add to their collection which includes all the species and innumerable hybrids. Their breeding work with the double forms has sparked national interest.  

The Tylers are co-curators of the Garden of Winter Delights at the J.C. Raulston Arboretum in Raleigh NC.  Their gardens have been featured in Southern Living, Virginia Gardener, Carolina Gardener, Heritage and Washingtonian magazines, As well as numerous newspaper articles and on Martha Stewart’s television program and magazine.  Judith is the author, with C. Coleston Burrell, of the new Timber Press publication entitled Hellebores; A Comprehensive Guide which features Dick’s remarkable photographs.
