Plant Focus: Cup Plant - a Living Focal Point for the Garden by Mary Tucker Page 10 I‟m not very adept at garden design, but I do know the importance of focal points, and I‟ve often heard garden lecturers recommend adding a sculpture to the landscape for just such a purpose. Southern Highlands Reserve Field Trip by Ellen Honeycutt Page 12 On June 1, 2010, GNPS members were fortunate to again tour the native plant gardens at Southern Highlands Reserve in Lake Toxaway, NC. The “Other” Dogwoods by John Little Page 16 Almost everyone is familiar with and appreciates the flowering dogwood (Cornus florida), the most popular landscape tree in the eastern part of the United States. 2010 Spring Plant Sale by Sheri George Page 18 The 2010 GNPS Spring Plant Sale was a wonderful success thanks to over 100 member volunteers who worked hard on Friday set-up day and braved the stormy weather for the sale on Saturday.

We look forward to and appreciate your continued support. Membership renewal forms for 2010 can now be completed online or by completing the form on the last page of this news letter NativeSCAPE July 2010 President‟s Message By Ellen Honeycutt As the days grow hot with summer, we look for ways to cool down. The tall canopy of mature oaks (Quercus sp.), hickories (Carya sp.) and tuliptrees (Liriodendron tulipifera) provides welcome shade, and I am thankful for these majestic native trees. The air can be 10 degrees cooler in the shade (and those leaves are an excellent sunscreen!). When it comes time to choose trees for your own yard or neighborhood project, remember the cooling shade of these trees during the summer and the relief they will provide to you and to future generations. Fall is the best time to plant trees and, believe it or not, it is just around the corner. The 2010 Garden Tour is but a memory now, but a pleasant one. Several hundred members took the time to visit one or more of our member gardens on April 18 th. Thanks to Cindy, Julie and Faye for opening their personal gardens to us. The Stone Mountain Nature Garden and our own propagation area at Stone Mountain were also on the tour and provided members with an opportunity to see the progress made in both sites. The 2010 Plant Sale was a wonderful success – we sold over $21,000 worth of plants! So many people helped to make this possible – from the Plant Sale committee, to the dozens of volunteers, to the members that donated plants, to the nurseries that donated plants, and to the hundreds of customers that bought them all! Thank you all so much for demonstrating that the demand for native plants is stronger than ever. We have a few plants left over, so look for announcements about plant sales at meetings and various events throughout the year. A lively group of folks turned out to hear about Ferns at our May meeting and were treated to a variety of special things – the GNPS scrapbook was on hand for viewing, we sold plants and t-shirts, there was a free raffle, and one of our board members brought a huge cake so we could celebrate her birthday! Please plan to attend our meeting on July 13th – it‟s sure to be just as fun (as well as educational). Come early and enjoy the new features at the Atlanta Botanical Garden. Our 2010 Symposium, which was snowed out in February, has been rescheduled to September 25th. Information is already on the website and should be reaching your mailbox soon. The location is the same (North Metro campus of Chattahoochee Technical College in Acworth, GA) and many of the speakers have been rebooked. In addition to an assortment of talks, we‟ll have vendors selling plants, art, books and other items. I hope to see many of you there – it‟s a great opportunity to learn as well as socialize. In late May, I had the opportunity to meet with folks from other native plant societies during the FNPS (Florida) conference in Tallahassee. It was good to learn more about how each of them interact with their members and support issues in their state. The purpose of the meeting was to begin an effort to join together and collaborate on some common issues: endangered plants, land advocacy, invasive plants in the wild and in nurseries, as well as encouraging more nursery production of native plants, and the continued growth of our own societies. It looks like a promising start to building a partnership that will help each of our groups, both the large and the small, to be more effective in supporting our efforts in education, conservation and preservation. 3 NativeSCAPE July 2010 Nominations Are Now Open... by Paula Reith … for 2011 GNPS Plant of the Year! The purpose of the GNPS Plant of the Year program is to recognize native plants in the landscape which benefit our wildlife and ecology. GNPS should continue to highlight native plants that are underutilized in commercial and domestic landscapes or which are vital components of our Georgia ecology. We are looking beyond beauty, even though we acknowledge that this is often what draws us to a special native plant in the first place. GNPS members may nominate any plant which is native to Georgia until October 15th. You are limited to nominating only one native plant. You may nominate online: http://gnps.org/forms/ POY_Nomination.php Or send your nomination via email to: [email protected]. Butterfly Weed (Asclepias tuberosa) Photo Credit: Mike Strickland Include the common name, scientific name and your reason for nominating your native plant in your nomination. After the nomination process has closed, the nominated native plants will be posted on the GNPS website. GNPS members will select the Plant of the Year by voting either electronically or in person at the November general meeting. Electronic voting either via the GNPS website or by email ends at midnight November 8th preceding the November 9th general meeting. Below is the link to the annual Plant of the Year winners. http://gnps.org/poy/Plant_of_the_Year.php 4 NativeSCAPE July 2010 Buffalo Creek Restoration by Flo Hayes During a work day at Buffalo Creek on May 15, the West Georgia Chapter of GNPS (WGC of GNPS) received some welcome help from Cub Scout Pack 2345. The boys and their leaders, Erica McConnell, Wolf Den leader, Angel Harden, Assistant Wolf Den leader, Randy Galbraith, Assistant Cubmaster, and parents worked to remove privet and honeysuckle from the front of the trail. They did a wonderful job. They have asked to be included again in another workday and are very excited about this project. Other members of WGC of GNPS worked removing larger privet and unwanted small trees as well as invasive plants from an area to be planted with mayapples (Podophyllum peltatum), hepaticas (Hepatica americana) and other rescued shade plants. Cub Scout Pack 2345 Photo Credit: Sara Gilbreth In early June some members of WGC of GNPS made another walk over in the area near the trail head and identified additional plant material. Among the plants found were a New Jersey Tea (Ceanothus americanus) in full bloom, a nice stand of Solomon's Seal (Polygonatum biflorum), Sweet shrub (Calycanthus floridus) with a lighter bloom than usual, and some beautiful Fire Pink (Silene virginica). Many other desirable plants were noted and our excitement increases as we have a chance to work on this trail and identify plants and habitats. Volunteers Hard at Work Photo Credit: Gina Strickland 5 NativeSCAPE July 2010 Invasive Plant in Profile: Nandina domestica by Ellen Honeycutt Nandina domestica is a plant of Asian origin (China, India) that has been used in Southern gardens since the early 1800‟s. One common name is Heavenly Bamboo because of its resemblance to bamboo in growth habit; it is also simply known as Nandina. Nandina domestica is an evergreen or semi-evergreen woody shrub that grows to 8 feet, although smaller cultivars have been developed. Leaves are alternate, large, bi- or tri-pinnately compound with small leaflets. Flowering occurs in the spring, when small, white flowers develop in large panicles at the ends of the stems. Fruits are green berries that mature to a bright red and are often used in holiday decorations. Nandina domestica has shown invasive properties in warmer climates, especially Florida. It spreads in two ways: through dispersal of seeds by wildlife, like birds, and also by underground stolons. In Georgia, plants occasionally show up in natural areas and adjacent properties because of seeds; its spread by stolons is primarily limited to the area around the plant. According to the Georgia Exotic Pest Plant Council, it is considered a Category 2 invasive plant: “Exotic plant that is a moderate problem in Georgia natural areas through invading native plant communities and displacing native species, but to a lesser degree than category 1 species.” Nandina in Flower Photo Credit: Ellen Honeycutt In my area, which is about 30 miles north of Atlanta, I have seen Nandina growing on the side of a rural road where it is clear that no one would have planted it. I also find it occasionally Nandina Berries in my wooded area, thanks to the fruits of my Photo Credit: Ellen Honeycutt neighbors‟ plants and the birds that brought them over. I probably pull out two plants per year in my two acres. Occurrence of volunteers in my immediate neighbor‟s yard is higher because they have the mature plants (there must be some rule of thumb here about how far away a bird poops from where he ate something!). (Continued on page 6) 6 NativeSCAPE July 2010 Invasive Plant in Profile: Nandina domestica (Continued from Page 5) adjust to the amount of insects available as a source of protein. So, if you have this, let me be clear: I‟d like you to get rid of it. Here are some replacement ideas for you to consider: Evergreen shrubs under 8 feet for sun/part sun areas: Nandina Seedling Photo Credit: Ellen Honeycutt You might say: “Why worry about a Category 2 invasive plant when there are 28 plants ahead of it on the Category 1 list?” What is one plant per acre per year (as in my case)? It‟s clearly not going to overwhelm us while we‟re standing here (like Kudzu). Consider that every mature plant becomes a parent to potentially dozens of new ones. Each berry in that cluster of 3050 berries can be a new plant. As those berries are dispersed into natural areas and untended roadsides, they grow up to be parents themselves. In a few years, each plant is making 30-50 new plants each year. The exponential growth from that first plant in the right environment yields hundreds and thousands of plants each year. In case you have a cultivar and haven‟t seen berries, these are the cultivars that are said to have little to no fruit production (often because they do not flower): „Filamentosa‟, „Firepower‟, „Gulf Stream‟, „Harbour Belle‟ and 'Harbour Dwarf'. Beyond the invasiveness factor, don‟t forget that using a non-native plant instead of a native one means less food materials for insects that eat only native plants. Fewer insects mean fewer birds as bird populations Agarista populifolia „Leprechaun‟ Ilex glabra „Compacta‟ up to 6 feet Ilex glabra „Shamrock‟, slowly growing to 5 feet Morella cerifera „Don‟s Dwarf‟, „Fairfax‟, both up to 6 feet Morella cerifera „Suwanee Elf‟, seems to be up to 4 feet Leucothoe fontanesiana, up to 5 feet (L. axillaris is similar) Shrubs with colorful berries: Ilex verticillata „Winter Red‟ or „Red Sprite‟ Photinia pyrifolia „Brilliantissima‟ (Aronia arbutifolia) Callicarpa americana, Beautyberry Viburnum nudum var. cassinoides Viburnum opulus var. americanum, American cranberry bush 7 NativeSCAPE July 2010 Chapter News By Gina Strickland The West GA Chapter of GNPS participated in the Hydrangea Festival in Douglasville on June 4-6 in the Educational Division. Our entry was about the GNPS rescue program and was titled 'Rescue Me'. The Rescue Me entry was awarded the First Place ribbon for Educational display. Photo Credit: Gina Strickland Photo Credit: Gina Strickland On June 12, a group from the Chapter made a field trip to the Birmingham Botanical Gardens in Alabama. The Curator for Kaul Wildflower Garden and trail, John Manion, gave us a guided tour. Even though it was a hot trip, we enjoyed it and learned quite a lot about the garden creation and landscape design as well as the many fine specimens of native plants. Photo Credit: Mike Strickland 8 NativeSCAPE July 2010 Native Plant Rescue News By Lynn Almand Rescue schedule The spring and early summer plant rescue season is over, and we will wait until September to start the fall rescues. There may be a few pop-up rescues, but only if the weather allows. Please remember to water your newly planted treasures until they are well established. This is a good time to plan where you want to put your fall and winter rescue plants, as this is the best time to plant almost everything--especially shrubs and trees. Think about what will do well in your garden. Do you have the perfect setting for a serviceberry (Amelanchier) or a Piedmont azalea (Rhododendron canescens)? Is there an area that you could start a fern glade? Time to dream while relaxing somewhere cool... Facilitators Each issue I tend to brag about our facilitators and their efforts to lead rescues for you. Well, this time is no exception, but I want to share with you some of the other ways our facilitators are helping the environment. They are working hard as volunteers in public gardens, Master Gardener projects, and in schools. I asked them to share their "other native plant lives." Here are some of the things they sent me: Georgia Perimeter College Native Plant Botanical Garden Karen Lindauer reports: Many rescued plants have enhanced the woodland gardens and the Jeane Reeves Memorial Garden at GPC Botanical Gardens. In fact, just before one of our rescue sites was bulldozed, we transported enough granite rocks, soil from the solution pits and plants to establish an outcrop area at GPC, complete with Stone Mountain Daisies (from seed in the soil). When the outcrop bloomed the September after we planted it, George Sanko told us that he didn't think it would work. When asked why he let us do it, he said that's what GPC Botanical Gardens are all about--pushing the limits. From Bill Belknap: If you have never been to the GPC garden, it's worth a trip. Lunch and Wildflower walks and talks are available in spring and fall as well as periodic plant sales. It's close to the intersection of I-20 and I-285 in Decatur and is open from dawn to dusk for free. For more information, go to www.gpc.edu/~decbt/. Other facilitator volunteers there include: Susan Todd, Kathryn Gable, Paula Reith, and John Little. Mary Scott Nature Preserve Beth Nation reports: Since 2003, when 10.6 acres of less-than-pristine woodland in my neighborhood were acquired by DeKalb county (later designated a nature preserve), I have been deeply involved in the Master Plan process, then in lobbying for completion of the essential hardscape for which funding was available. This spring, my focus has turned to organizing a Friends-Of-The-Park organization to guide MSNP's future development and maintenance, and to host regular workdays. I am propagating some of my rescued plants for use there, particularly ones rescued within 20 miles and typical in mesic, slightly sweet conditions. For driving directions, go to http:// www.decaturpreservationalliance.org/woodlands.php. (This is a GNPS restoration project.) Heritage Park Connie Ghosh is the committee chair for this GNPS restoration project. Her reports and the workday schedule can be found at http://gnps.org/restoration/Restoration_Index.php. Facilitators who volunteer there include Sheri George, Ellen Honeycutt, David Zaparanick, and Marcia Winchester. Marcia Winchester tells us this about her experience there: I've donated rescued plants and arranged several rescues to dig plants for Heritage Park when we needed some plants for erosion control. When we use rescued plants in a restoration project, we use plants that would normally be found there and follow natural distribution patterns. We use logs and rocks to help stabilize the plants and keep them in place until their roots are strong enough without support. People walking in the park are so excited to see the plants. We've added lots of Christmas fern and last winter a glade of 14 fragrant native Azaleas. I love to watch the walkers slow down so they can enjoy the woods. (Continued on page 9) 9 NativeSCAPE July 2010 Native Plant Rescue News (Continued from Page 8) Panola Mountain From Susan Todd: I do volunteer work at Panola Mountain State Park. One of my favorite duties is leading hikes on the Granite Outcrop trail for elementary school field trips. We talk about the different ecosystems along the trail and how wildlife use the plants in each system. We also talk about the granite outcrop - how it forms and how plants survive there. The children especially like the wonderful stand of low bush blueberries. They can relate to blueberry pancakes no matter how young! Currently, my garden club, Evergreen Garden Club of Conyers, is reworking a flower bed in front of the nature center at Panola as our project for the year. We have cleaned the bed up and found a good number of native plants. We will "beef up" the groups of natives and add a few more groups. We plan to put in signage so the staff (and I) can use the bed as a teaching tool. All plants will be native and indigenous to the Park. I am using plants from rescues as I can find them. The goal of this project is education of local native plants. and more: Karen Lindauer leads the Fern Creek Habitat Restoration Project at the Unitarian Universalist Congregation of Atlanta. Ellen Honeycutt is helping out at the Dunwoody Nature Center. Beth Nathan represents her county commission district on DeKalb's Parks Bond and Greenspace Citizens Advisory Board (CAB), which advises on project selection and monitors expenditures from county parks bond funds. Among other things, she interacts with county staff and other CAB members about current plantings and invasives during bimonthly tours of existing parks. Marcia Winchester has this to say about her Master Gardener project: I'm passionate about the Butterfly Garden in my master gardener demo garden. A few years ago I took one section and put in only natives from rescues. At our workday last week everyone was taking pictures of the native section. It is just beautiful. It has both Asclepias tuberosa and A. variegata, Jeane‟s (Reeves) favorite Phlox, P. paniculata, Passiflora lutea, Ceanothus americanus, Coreopsis major all blooming together. I love pointing out all of the different native plants to viewers of the garden. There are natives blooming from April to frost. Last year I harvested milkweed seed and mailed them to Monarchs across Georgia to use in their butterfly program. One thing, I never let anyone else weed this garden.

The Path at the Master Gardener Demo Garden Photo Credit: Marcia Winchester Facilitators have held special rescues for The Woodlands in Decatur, Oakhurst Community Gardens, the Chattahoochee Nature Center, Grant Park, Suwanee Greenway, and many rescued plants have been planted in neighborhood gardens throughout Atlanta. I know that many, many of you also volunteer your time in similar ways because I've heard you talk about it on rescues, seen your names on rescue signup sheets, and lists of restoration project volunteers. The Stone Mountain Propagation Project is staffed by GNPS members. I'm very proud we are working to preserve our Georgia treasures and beautify our communities with native plants, and I hope you are also. 10 NativeSCAPE July 2010 Plant Focus: Cup Plant - a Living Focal Point for the Garden By Mary Tucker I‟m not very adept at garden design, but I do know the importance of focal points, and I‟ve often heard garden lecturers recommend adding a sculpture to the landscape for just such a purpose. I‟ve found that a sculpture need not be fashioned of stone or steel. In my garden, the most dramatic and sculptural focal point is a towering native perennial, cup plant (both Silphium connatum and S. perfoliatum go by this common name). I was first introduced to Silphium connatum at the Cullowhee native plants conference in 1998. For those of you who are unfamiliar with this conference, it takes place at Western Carolina University in Cullowhee, NC, and its official title is “Native Plants in the Landscape.” But those of us who are regulars just call it Cullowhee. This year is the 27th anniversary of its inception, and it will be held from July 28-31. For more information or to register, visit http:// nativeplantconference.wcu.edu. Photo Credit: Mary Tucker But back to cup plant! While browsing through the plant vendors at Cullowhee that year, a striking plant called Silphium connatum caught my attention. It was for sale by Peter Heus, proprietor of Enchanter‟s Garden in Hinton, West Virginia. This plant had bold, unusual foliage and a lovely yellow, daisy-like bloom. The genus Silphium was already a favorite of mine, but I was not familiar with Silphium connatum. I learned from Peter that it is endemic to West Virginia and that it likes rich, moist soil. So I took it home and found a place for it in an intermittently damp, sunny spot in my garden. Since that time, it has surely become one of my favorite plants, largely due to the dramatic architectural quality it lends to the garden. By the time it begins blooming in mid to late June, it has reached 7 feet in height and 3 to 4 feet in width. The statuesque nature of these plants adds a distinct dimension to the summer landscape. In addition to serving as living sculpture, they can be employed as a seasonal screen or hedge. My own collection of cup plant encircles a stone patio, providing privacy in summer when it is most needed. The robust foliage is truly impressive, and the leaf form adds a delightful sculptural accent in the garden, just as lovely – in my opinion – as the flowers. The leaves are opposite one another on the stem, and the larger, mature leaves (which can be up to two feet long and one foot wide) are fused at their bases, forming a “cup” (hence the common name) around the stem. Rainwater pools in these living vessels, providing songbirds with a drink. Peter Heus told me that he has even seen small songbirds bathing in these cups! It is also said that early settlers and Indians drank rainwater from the leaves; hence, you may hear the plant referred to as Indian cup. The leaves are covered with small stiff hairs and have a somewhat serrated edge, which is more pronounced on older leaves. The purple-tinged stalks are square, and on mature plants they are about an inch wide at the base. Despite the plant‟s height, this sturdiness of stem means that the plants don‟t require staking (at least in my experience). In fact, I leave the dead stalks throughout the winter for the birds to land on as they approach the nearby birdfeeder. Many of these stalks are still standing in late spring, a testament to their durability. Silphium connatum is kin to Silphium perfoliatum, which is more widely known by native plant gardeners. The (Continued on page 11) 11 NativeSCAPE July 2010 Plant Focus: Cup Plant - a Living Focal Point for the Garden (Continued from 10) USDA Plants Database (http://plants.usda.gov) and NatureServe (http://www.natureserve.org) both show its preferred name as Silphium perfoliatum var. connatum, but Peter Heus grows them both and says he considers them two distinct species, as does the book Flora of West Virginia published in 1977. I have spoken with other botanists and they, too, believe it is a separate species. Peter notes that, compared to S. perfoliatum, the leaves of S. connatum are broader where the stem comes through, forming a wider cup. He also says that there is less pronounced serration on the leaf and that it flowers earlier than S. perfoliatum. The bloom time of the two does overlap, and hybridization may occur. Bees and butterflies are attracted to the 2- to 3-inch yellow flowers, and birds (especially the goldfinch) adore the seeds. I have had no problems with any pests on my plants, and the deer have not bothered it – probably due to the hairy nature of the foliage. From my research, I understand that the seeds need a cold period to break dormancy, so I just let whatever seeds the goldfinches don‟t eat fall to the ground near the mother plant. When the weather begins to warm in the spring, seedlings will appear. In the flower heads of the Silphium species, only the ray flowers are Photo Credit: Mary Tucker fertile; therefore, though you will get some seedlings in your yard, you should not be overrun with them. Dig the seedlings for sharing or transplant while fairly small since they develop extensive root systems and can be difficult to move after putting on some size. Though most Silphiums are found in dryer habitats, cup plant is quite tolerant of moist conditions. Its home in the sunny bed at our patio can be fairly damp at times, which some gardeners would consider a problem. However, I‟ve managed to use this to advantage to grow both cup plant and some lovely native companions. Among them are cardinal flower (Lobelia cardinalis), ironweed (Vernonia noveboracensis), Virginia sweetspire (Itea virginica), seashore mallow (Kosteletskya virginica), scarlet rosemallow (Hibiscus coccineus), crimson-eyed rosemallow (H. moscheutos), swamp sunflower (Helianthus angustifolius), spider lily (Hymenocallis caroliniana), turk‟s-cap lily (Lilium superbum), scarlet beebalm (Monarda didyma), blue flag iris (Iris virginica), copper iris (I. fulva), and lamance iris (I. brevicaulis). Photo Credit: Mary Tucker Cup plant is offered for sale by some native plant nurseries, either by seed or plant. You may also find it for sale occasionally at GNPS meetings or at the GNPS annual plant sale. Give it a try if your garden needs a dramatic focal point. 12 NativeSCAPE July 2010 Southern Highlands Reserve Field Trip By Ellen Honeycutt On June 1, 2010, GNPS members were fortunate to again tour the native plant gardens at Southern Highlands Reserve in Lake Toxaway, NC. Members from the Georgia Botanical Society participated as well. The Southern Highlands Reserve is located in western North Carolina at an elevation of 4500'. SHR is a private native plant garden and research center dedicated to the preservation, cultivation and display of plants native to the Southern Appalachian Highlands. Naturalist Richard Bryson and Executive Director John Turner were our guides. Before the tour started, we got a peek at some of the propagation efforts. SHR staff are propagating native azaleas and red spruce both for their own use and for use by other non-profit groups. Please see more about this effort on their website (http:// www.southernhighlandsreserve.org/blog/john/ shr-begins-ecological-restoration-program). Trip Attendees Photo Credit: Ellen Honeycutt Unlike our trip in May 2009 (http://gnps.org/fieldtrip/ Southern_Highlands_Reserve_09.php), the Rhododendron vaseyi had finished blooming and the waterfall hike was unavailable due to winter ice storm damage. However, since our trip this year was a month later, we were able to see completely different plants in leaf and in bloom! We started out with a tour of the Wildflower Labyrinth which contains many herbaceous perennials in bloom now and will continue to be spectacular into the fall. Huge Baptisia plants dominated the beds. Vaseyi Seedlings Photo Credit: Ellen Honeycutt The Labyrinth Photo Credit: Ellen Honeycutt (Continued on page 13) 13 NativeSCAPE July 2010 Southern Highlands Reserve Field Trip (Continued from Page 12) From there we went down through the Azalea walk on our way to the Vaseyi Trail and Pond. The Azalea walk was colorfully populated with many blooming Gregory Bald hybrid azaleas in striking shades of orange and red. Azalea grown from seeds found on Gregory Bald Photo Credit: Ellen Honeycutt Azalea grown from seeds found on Gregory Bald Photo Credit: Ellen Honeycutt We also saw blooming False Solomon‟s seal (Maianthemum racemosum), Clintonia lily (Clintonia umbellulata), Solomon‟s seal (Polygonatum biflorum), still blooming Columbine (Aquilegia canadensis), Goatsbeard (Aruncus dioicus), and large, lush swaths of Hayscented fern (Dennstaedtia punctilobula). Clintonia Lily Photo Credit: Ellen Honeycutt Along the Vaseyi Trail, Galax urceolata was sporting shiny new foliage and crisp white flower wands. Winding our way through a forested trail, we finally arrived at Vaseyi Pond, which was surrounded by lush gardens, gorgeous mountain views and full of fat bullfrog tadpoles! Here members of the trip spread out to explore the many plants and rest areas. Galax urceolata Photo Credit: Ellen Honeycutt (Continued on page 14) 14 NativeSCAPE July 2010 Southern Highlands Reserve Field Trip (Continued from 13) Just beyond the pond awaited a view site like no other we‟d seen that day. The mountains stretched out from there, as far as the eye could see. Blooming Rhododendron hybrids (perhaps a hybrid between R. maximum and R. catawbiense) framed the view. Vaseyi Pond Photo Credit: Ellen Honeycutt Mountain Vista Photo Credit: Ellen Honeycutt Naturally occurring Mountain Laurel (Kalmia latifolia) peaked out from the forested edges all around, and delighted us with their pink blooms and buds. It was peak time for Mountain Laurel all along the roads near the entrance to the Reserve and it was nice to examine them closely here.

The trails are sometimes facilitated by constructed bridges, boardwalks and steps to make the hike more secure. A lovely clump of still blooming pink lady slippers (Cypripedium acaule) awaited our final exclamations, a nice surprise to finish our trip. Laurel Trail Photo Credit: Ellen Honeycutt Back at the Preserve facility, we enjoyed our sack lunches and the spring blooms around us. The conversation was a lively combination of tales of previous field trips, native plants and, strangely enough, ice cream ….

Whether planted as a specimen or found in its natural home as a dominant understory tree lighting up the spring woods, it has been called the “aristocrat of native trees” by Michael Dirr. It provides exceptional beauty all year with its showy white blooms in the spring, red leaves and fruit in the fall, and “alligator skin” bark in the winter. Perhaps because it is so well known and loved, many gardeners and plant enthusiasts think of nothing else when the word dogwood is mentioned. There are, however, several other Cornus species native to the southeastern United States which, while not so spectacular, deserve more attention and use for detail interest in select places in the landscape. Several of these other species are Cornus alternifolia (pagoda or alternateleaf dogwood), Cornus amomum (silky dogwood), and Cornus foemina (swamp dogwood). They are usually shorter than C. florida and more shrubby in character with showy, flat-topped cymes or clusters of 1/4-inch creamywhite flowers. They may be especially useful where their horizontal features can be utilized to accent sharp vertical lines, perhaps by massing or growing as a multi-stemmed shrub. At close range, you will notice attractive stem colors and texture. Alternate-leaf dogwood (Cornus alternifolia) Photo Credit: The Dow Gardens Archive, Dow Gardens, Bugwood.org The pagoda dogwood probably has the most potential of the three as a landscape plant. It rarely grows taller than 15 to 25 feet and is more commonly smaller, with several main stems. It may be as wide (or wider) as it is tall. The branches sweep out in horizontal tiers nearly parallel with the ground (hence the name “pagoda”). Each branch and twig forks in a Y-shaped pattern giving them a flat aspect. As you might guess from the botanical name, this tree has alternate leaves, the only alternate-leaved dogwood native to North America. This characteristic can be overlooked because the leaves are mostly crowded at the ends of twigs and not obviously alternate except on long twigs. The 2- to 5-inch long leaves are similar to C. florida and may turn reddish-purple in the fall, but don‟t count on it. More dependable, and especially notable, are the lustrous reddish-brown stems (sometimes green) and colorful fruit clusters. The fruit (drupes) turn from green to red to blue-black and are perched on stemlets that are deep red at maturity. About 1/4- to 1/3-inch long, they attract numerous birds and are occasionally browsed by deer and rabbits. Silky Dogwood (Cornus amomum) berries Photo Credit: www.nativehaunts.com You might not want to plant a pagoda dogwood too close to your patio or deck, as some say the flowers are unpleasantly fragrant. Instead, plant it near a tall tree or structure or on a creek bank. It likes a cool root zone, but grows naturally in moist to dry habitats. (Continued on page 17) 17 NativeSCAPE July 2010 The “Other” Dogwoods (Continued from Page 16) Silky dogwood is shorter and more shrubby in habit than pagoda dogwood. It typically occurs in wetlands and along streams or ditches. Indeed it may be useful to help prevent erosion. Since it will tolerate wet soils, it might be allowed to form clumps in areas not suitable for most other shrubs. Stems are easily rooted, so you can increase your stand. It is said to form a good informal, unclipped hedge and to thrive in diverse locations, not just wet areas. Not likely to ever be a commonly used landscape plant, if you have enough space, it could provide additional diversity to your plant community. The young stems of the silky dogwood are reddish-brown or greenish, silky, hairy and grow 6 to 10 feet in height, spreading to equal width. Whitish or yellowish, flat flower clusters, which are not fragrant, appear in mid to late spring and produce blue drupes similar to C. alternifolia. Sometimes they may have cream coloration. The birds and other natural forces cause them to quickly disappear. The leaves are superficially similar to other dogwoods and sometimes produce good reddish-purple fall color. I mention swamp dogwood because I believe I rescued a couple of small specimens recently. Part of the fun of participating in a plant rescue is finding an unfamiliar, but interesting, plant and doing the “detective work” to identify and learn about it. It was growing on a hummock in a swampy area, but what caught my eye were the clusters of red stemlets reflecting the sunlight. There were no fruits in sight, testimony to what was evidently a picnic spot for the birds. Whether what I dug was Cornus foemina (a.k.a. stricta) I‟m not sure. It was late in the year, and what few leaves remained were dry. I‟ll be studying it next year and years thereafter looking for the yellowish flower clusters, blue to purple drupes, appressed stem hairs and white pith I‟ve read about. For now, I‟m content to know I have another one of the “other” dogwoods for my plant collection. (These trees were eventually confirmed to be C. foemina based on the whitish color of the pith - not sandy brown, as in C. amomum - after splitting a pencil size stem.) 18 NativeSCAPE July 2010 2010 GNPS Spring Plant Sale By Sheri George, Chair GNPS Plant Sale The 2010 GNPS Spring Plant Sale was a wonderful success thanks to over 100 member volunteers who worked hard on Friday set-up day and braved the stormy weather for the sale on Saturday.

On a construction site, you can often see those huge steel box-like containers full of wood scraps, pieces of drywall, cardboard boxes, pieces of metal flashing, plastic pipe remnants, shingle scraps, almost every type of garbage generated in building a house. It has not always been this way. For many years, contractors who were building new houses were able to get rid of construction debris by simply digging deep pits into which they dumped all trash materials. They would then cover these garbage pits with dirt, pack them down, smooth them out and seed a lawn. It was permissible and the garbage was thought to be gone. Out of sight, out of mind! Well, after a few years, these nice, smooth yards started developing depressions - the garbage was decaying and the cover top soil was sinking. The depressions became caverns! At this point, I can speak from personal experience. My house is about thirty years old and I have been in it for ten years. About five years ago, parts of my yard started sinking! They sank deep and they sank fast! Huge pits! There are two of them. The smaller one is circular and way in the far back of the yard. It is about 8 feet in diameter and maybe 2 feet deep. The other one is close to the rear of the house. It is the big one and rather intimidating. It is 30 to 35 feet long, from 9 to 12 feet wide, and from 2 to 5 feet deep. Recently, I heard on a popular gardening show on the radio that there is only one solution to such a garbage pit fill it in. The host said that you could fill it in yourself - a lot of work bringing in dirt and rocks, shoveling it in, packing it down, etc. The alternative was to hire it out to someone that could bring in dump trucks of dirt and front-end loaders to fill and finish the area - assuming it was accessible. Both methods sounded destructive to the rest of the yard as well as to the bank account. My philosophy has always been: cooperate with nature and deal with what you are dealt. I have devised two other methods that are not destructive and cost nothing except a little patience. I made a compost pile out of the small circular pit. It was at the back in the utility area and I just keep filling it with yard debris - leaves, twigs, clippings, etc. Working great. I have stopped taking compost from it but am ending up with a very rich circular garden area. Rather charming. The big cavern is still a work in progress. I am making a combination pond/bog out of it. I have always wanted a pond and a bog so this was fate. I threw piles of leaves in it to decay and smooth out the bottom; I have also handfilled with dirt some of the deep holes that appear in the sidewalls. The pit holds water pretty well as seen in the recent downpours, but I plan to line it with a heavy rubber membrane - from a yard sale. I will use an old fiberglass pool form for the bog area - also from a yard sale. The sides of the cavern are somewhat steep. Along the higher side of the hole, I am planting a barrier fence of shrubs, especially thorny ones. Below the barrier shrub fence, all kinds of ferns, especially Christmas ferns (Polystichum acrostichoides), are tucked into crevices and on ledges. It is important to have many evergreen plants in the barrier. Foam flowers (Tiarella cordifolia) are also great for this area. Along the lower side is a little walk and garden. Again, ferns line the bank. I have amassed a collection of water-loving plants from rescues and from friends to put into the pond and the bog. Then all I will need is some fish! So, there are 3 ways to handle construction pits - fill them in, make a compost pile, or create a pond/bog. Have to think outside the box or, in this case, the pits! 21 NativeSCAPE July 2010 UPCOMING EVENTS July 13, Member Meeting - The Natural Gardens of America Alaska: Please join guest speaker, Rick Barnes, as we journey from the top of the Alaska Range, on the slopes of Mt. McKinley where nothing will grow, descending to the rich flora of the Alpine Tundra. Descend further still to the open forests of the Taiga: a segment of the Great Boreal Forest, the largest of the six floral kingdoms on earth. Our journey ends in Alaska's coastal rain forest, a region of mountains, waterfalls, and lush vegetation. Along the way, discover the forces that conspire to make Alaska one of the most unique and changeable gardens in the world, and discover its similarities to many areas of the polar region and alpine climates of the northern hemisphere.
