Michigan was as hot as Atlanta and their drought may even have been Dwarfs After25 Years By Maud Henne ,VA p. 10 worse. That didn’t stop us from visiting some great gardens. Events: SE Region Meeting August 17–19, 2012 Asheville, NC Arborfest Blandy Farm October 13-14, 2012 Boyce, VA The first day was spent at Hidden Lake Gardens -, a 755 acre garden owned by Michigan State University. In spite of being there all day, I covered less than half of it. The heat slowed me down. It harbors the famous Harper Collection of Rare and Dwarf Conifers. And what a collection it is! It is named after Chub Harper who donated most of the plants and was a long time ACS member. In fact, the next day we toasted him on what would have been his 85th birthday. Sadly, he is no longer with us. Also, hosta lovers (over 800 varieties) and bonsai enthusiasts would find much to appreciate at Hidden Lake. I have to confess that one of the highlights for me was a collection of 20+ black walnut, Juglans nigra, trees. A couple were over 3 feet in diameter. On the 2nd day we visited three gardens. The first was the 10 acre home of Michael and Remedios Young. It had been a sunny property of grass and the owners were inspired by Gary Gee to transform it. They started less than 10 years ago and have over 250 different conifers. It looks like they have half their land left so this garden will continue to evolve. My personal favorite, on aesthetic grounds was the home of Sandy and Jim Wilkins, the second garden of the day. It was predominantly a shade garden with numerous mature hardwoods limbed up to provide high shade. I’m inspired to rent a 40 foot ladder to improve my own wooded area although my wife is not keen on my balancing acts on tall ladders. It was wonderfully landscaped with a great tranquil feel. Numerous sculptures and sitting areas completed the scene. Jim is a past president of the American Hosta Society and thus many hostas were incorporated into their garden. We finished the day at Gee Farms, a huge nursery with an adjacent arboretum. The property has been in the family for over 150 years and consists of several hundred acres. Although the arboretum is only 12 years old it has excellent specimens of hundreds of trees. Gary Gee is an ACS member and offered a discount to us at his nursery which many took advantage of filling the tour buses to capacity. We had a Board meeting at which Larry Nau (New York) was named president and Brian Jacob (Oregon) vice president.

We talked about other website enhancements making it more appealing and useful for members and other visitors. We plan to put links to conifer videos on the website within the next couple of months with more to follow as an ongoing educational tool and perhaps a little fun. There was considerable talk about the need to make ACS more interesting, more useful to members and more attractive to potential members. Larry will set some things in motion to help that over next year or so. We need to think about how to cast a wide net to attract a broad audience. Each of us should think about how to recruit new ACS members. Sue Hamilton accepted this year’s Marvin & Emilie Synder Service Award for Dedicated Support to the ACS on behalf of Flo Chaffin. I’m sure Sue will present it to Flo at the upcoming SE meeting in Asheville. Also, our own Barbie Colvin was named Chair of the National Reference Garden Committee. Her leadership in establishing 12 Reference Gardens in the SE puts us way in the lead and hopefully will inspire the other regions to grow their numbers. It was a good meeting and tour. I’m now looking forward to our SE Region meeting in Asheville, North Carolina this month. From the SE President: Asheville, here we come!! As I write this letter we are just a few weeks away from our regional meeting in beautiful Asheville, NC. I can’t encourage you enough to come to this meeting being held in one of the most beautiful areas of the Southeast! The host hotel is right in the heart of Biltmore Village with easy access to shopping and eating. We’ve planned a slate of wonderful gardens for your to visit where you’ll see beautiful conifer specimens and great examples of how to mix them with companion plants and to use them in the landscape. You won’t want to miss our Friday evening speaker, Rita Randolph, who is a famed gardening speaker and writer and also a fantastic commercial grower. She will share about the work she is doing with Biltmore House & Gardens in regard to propagating conifers and other plants from their historic landscape. And, of course, you don’t want to miss our conifer auction! Some of the newest, novel and unique conifers will be up for bid. You never know what gems you might find to add to your garden. So come join us in Asheville. It will be beautiful and a lot of fun. I hope to see you there. Tom Neff Sue [email protected] Sue Hamilton, Ed.D.

Primarily we start by saying that you must have an ‘anchor plant’, a year round accent, something sensational, out of the ordinary. Flowering trees are sensational for two or three weeks per year. Rhodies and azaleas do not last much longer and look like h--- the rest of the time. To me the answer is a conifer, or more precisely a gymnosperm. The rewards are for a lifetime once you get the hang of it. I did in the summer of 1983. We were living in NY State at the time. I happened to see an ad in a magazine that showed a Hinoki Cypress. I could not believe the beauty of that plant, even though at that time I was not a plant person. After buying some and promptly causing them to die, I became more interested in what it takes to grow the plants. I discovered the American Conifer Society. Hazel and I joined. It has been a love relation ever since. ACS has so many people willing to share their knowledge and experiences. We moved to Hendersonville in North Carolina in 1988, and after our house was built, started our 3 acre garden . Our property has many native plants like mountain laurel, azaleas, rhododendron and oaks. We added 23 cultivars of beech, Japanese maples and hostas. But conifers are our signature plant. We have about 300 of them from Abies to Chamaecyparis, Cryptomerias, Pinus, Taxus and Tsuga. A Taxodium ascendens (Pond Cypress) is submerged in our koi pond. Continued on page 6 Many people think of conifers as simply ‘pine trees’. What a narrow thought! The exciting feature about conifers is their tremendous diversity. An enormous variety of colors, textures, scents, structures, sizes and fruiting bodies is special to conifers. One needs to look only briefly at any conifer collection to realize the many variations. Growth rates from ¼ inch to 4 feet per year are typical possibilities. Textures vary from soft and lacy like Bald Cypress to stiff and prickly as in Picea pungens, and everything in between. Colors are an artist’s palette with many shades of green, yellow, blue for the foliage, pink, red and brown for the cones. I could never grow tired of looking at the fantastic diversity of conifers and encourage any plant person to do the same.

Text By Elizabeth Fogel and Seth Roadman Photos By Grace Chapman Lewis Ginter Botanical Garden in Richmond, Virginia has something for everyone. The garden first opened to the public in 1987, fulfilling the will of Grace E. Arents to establish a botanical garden named after her uncle, Lewis Ginter. At this time, little of the garden’s 81 acres were under cultivation, but it has changed and grown rapidly ever since. There are now over 35 acres under intense cultivation with more than a dozen themed gardens. The property includes a visitor’s center, two restaurants, and a classical domed Conservatory featuring changing displays and orchids. The education building houses a large library and several classrooms for the wide array of classes, workshops, and symposia offered. A 2 acre children’s garden offers endless handson activities for children and families. Whether you have 30 minutes or all day to explore there are many treasures, including countless beautiful conifers, to be found. The Margaret Johanna Streb Conifer Garden is a hidden gem off of the beaten path. Hugging the far end of our lake, it offers beautiful views of much of the garden. Built in 1995-96, this garden serves as our official conifer collection. A wide array of dwarf and slow growing conifers are inter-planted with perennials, minor spring bulbs and flowering shrubs. There are over 14 genera, 38 species and countless cultivars represented in this corner of the garden alone. But if you are coming to see conifers, you’ll want to explore the entire property. Beautiful conifer specimens from more than 27 genera can be found throughout the garden. The conifer collection throughout presents guests of the garden with a broad array of specimens that exhibit outstanding attributes including attractive foliage, bark, interesting bud formation and unusual form and structure. Foliage in our collection consists of many and varying shades of blue, green and yellow/golden varieties. Some of the conifers change hue in winter months. Other types display variegated leaf tips combining to make a wonderful range of color and interest such as Juniperus rigida ‘Hikari’. Both Thujopsis dolobrata and Fokienia hodginsii show glossy green foliage while the underside displays a silvery white color that is very attractive. Popular shades of blue in the garden include Cedrus deodara ‘Feelin’ Blue’, Pinus parviflora ‘Glauca’, Cupressus arizonica ‘Blue Ice’, Picea pungens ‘Royal Knight’, Pinus sylvestris ‘Beuvronensis’ and Pinus flexilis ‘Vanderwolf’s Pyramid’. Other conifers provide striking golden yellow color especially in the winter. Pinus strobus ‘Hillside Winter Gold’, Chamaecyparis obtusa ‘Lemon Twist’, Cryptomeria japonica ‘Sekkan-Sugi’, Thuja occidentalis ‘Pumila Sudworth’ are fine examples intermingled between other evergreen and deciduous trees in the garden. Brilliant yellow coloration of Ginkgo biloba in the Grace Arents garden provides spectacular autumn interest. Thuja occidentalis ‘Rheingold’ develops a copper bronze color in winter and Cryptomeria japonica ‘Elegans Nana’ a deep purple hue that begins when the days become shorter and nights cooler. Page 5 Southeastern Conifer August 2012 ————————————————————————————————————————————–———— A transformation of conifers in our collection begins when new growth emerges in spring and is most noticeable on Pinus and Picea species. New shoot growth, often referred to as “candles”, emerge covered in white colored hairs frequently of a different color from the leaves of the prior season. Pinus thunbergii ‘Thunderhead’ renders a white against green contrast when the growth begins. Other specimens in the collection that provide these attractive candles are Pinus densiflora ‘Oculusdraconis’ and Picea orientalis ‘Compacta’. Another important attribute of the conifers in our collection include their shape or form. Several Cedrus atlantica ‘Glauca Pendula’ are trained prostrate in the garden. Globose or ball shaped is most recognized and popular amongst dwarf conifers. Cryptomeria japonica ‘Globosa Nana’and Pinus mugo are excellent examples of this form. Fastigiate or columnar forms add to vertical interest and Juniperis scopulorum ‘Skyrocket’ found at the entrance of the Streb garden is an example of an upright form with erect branches. Pendulous forms such as Chamaecyparis nootkatensis ‘Green Arrow’ in the Streb garden and Picea abies ‘Pendula’ in the Flagler perennial garden present an eye catching focal point. Certain conifers in the garden have unusual forms which may best be described as intriguing. ‘Cristata’, a cultivar of Cryptomeria japonica, has congested foliage resembling that of coral reef while Cryptomeria japonica ‘Araucarioides’ found at the entrance of the Streb garden has twisted stems and leaves adding to its uniqueness. Picea abies ‘Ziegler’s Weeping’ is an interesting weeper in which branches literally lay across the ground. Pinus contorta ‘Spaan’s Dwarf’ and Pinus parviflora ‘Adcock’s Dwarf’ are unequaled dwarf varieties and have a place in rock gardens or small spaces. Taxodium distichum around Sydnor lake produce buttressed trunks and interesting knee-like formations that provide these trees with anchor support in wet conditions. Silvery undersides of Pinus flexilis ‘Vanderwolf’s Pyramid’ The natural globose form of Cryptomeria japonica ‘ Globosa Nana’ The more mature conifers often develop impressive and attractive bark. Pinus densiflora ‘Umbraculifera’ in the Asian garden exhibits exfoliating bark that is reddish brown in color. This tree is grown as a standard to reveal the handsome bark. Pinus bungeana behind the Flagler pavilion exhibits bark that exfoliates in patches of green, grey, white and brown. In the conservatory, Araucaria bidwillii has sharply pointed leaves on the trunk that adds an element of appeal. This is just a small sample of the treasures to be found at Lewis Ginter, and whatever your preference, you are sure to find something to delight. You must visit in every season to fully appreciate all that the garden has to offer conifer lovers. Proud to be an ACS member garden, we continue to add to our collection as we can. Picea abies ‘Ziegler’s Weeping’ climbs over a small boulder.

And, it’s no surprise for those of us who appreciate the characteristics of this smallstatured conifer. It exhibits different colors based on which season it is. The way the color changes on ‘Morgan’ sort of reminds me of the metal copper. It's almost as if the colder weather removes the green tarnish to reveal copper colors on the exterior of the plant; then, with the arrival of spring we see the emerald green patina return. We can grow many plants We have a very plant compatible climate. Within 50 miles we have more genera than all of Europe. There is one exception: Firs do not do well here, it is at times too warm. They prefer the colder climate zone. Hazel and I spend almost every day in the garden. We can honestly say that we prune every tree and bush somewhat every year, some severely, some slightly. Otherwise you get too much of a jungle. We are looking forward to have our ACS friends visit us during the 2012 SE Region Meeting in Asheville. It is a fairly slow-growing cultivar, usually growing less than 4 inches in a year, and it is hardy in USDA zones 5 through 8. The small size warrants its use in containers. As with all conifers ensure that it has good drainage. The foliage sprays on this cultivar remind me of rigid cardboard cutouts that have been glued together; overall, the planar look is an interesting textural addition to the garden. While ‘Morgan’ is a great conifer to choose for year-round interest, you could add even more to the effect by pairing a grouping of them with the airy foliage of Mexican feather grass (Nassella tenuissima) or the more stolid, variegated blades of ‘Color Guard’ yucca (Yucca filamentosa).

Emphasis is on plants native to the Southern Appalachian region. The Arboretum features among others the Quilt Garden with colorful raised beds designed after traditional quilt patterns, and the Heritage Garden featuring plants used in traditional folk medicine and crafts of the Appalachians. The Arboretum is also home to a Bonsai Exhibition Garden showcasing one of the best collections of bonsai in the Southeastern United States, with special emphasis on native plants. The Elmore Garden The garden of Dr. Miles and Millie Elmore Asheville, NC is a Smithsonian Garden ( part of the Smithsonian Institute). It features everything that a gardener enjoys: a mixture of a wide range of plant material, a greenhouse, an herb and a vegetable garden, a pond and a new woodland garden.

Who would not want a pine with long needles in blue and cream -Pinus wallichiana ‘Zebrina’ -, or a hemlock with white needles at the tip of branches -Tsuga canadensis ‘Snow’-, or the yearlong golden/yellow needles of Picea abies ’Skyland’? Who does not like the soft blue foliage of the Chamaecyparis pisifera ‘Boulevard’’ or the interesting texture of Juniperus squamata ‘Blue Star ’ ? Maybe we want a nice bright green ground hugging plant like Juniperus procumbens ‘Nana’. Or we fall in love with the threadleaf branches of Chamaecyparis pisifera ‘Gold Mop’. Oh, they are so cute in their 1 gallon pot at the nursery or at the auction. We are dealing with dwarf conifers, right? If we are lucky, there will be labels giving us some information about the growth habit of the plants. From what I know these data are meant for the next 10 years. But be aware that after that they keep growing. Reinhard Henne, my late husband, started our conifer collection in 1987/1988, meaning some of my plants have been in the ground for 25 years. They did not stop growing after 10 years. And that is what this and later articles are about: I want to show how plants that we perceive as being dwarf will do in 25 years if not pruned. Compared with the giant redwoods in California, they are still dwarf, but they might outgrow the space we allocated in our garden. On purpose, I did not prune the plants shown here. I wanted to see what these plants will do. But this year I started to cut back some branches of Juniperus ’procumbens’ which were growing into my pathways. The sizes given are for one plant. Photo on right: Cryptomeria japonica ’Elegans Nana’: 12 ft in diameter, up to 4f t high Juniperus procumbens 22 ft long, 20 ft wide, 2 ft high Juniperus squamata ‘Blue Star’ 8 ft in diameter, up to 2 ft high
