2005 Georgia Gold Medal Winners Dragon Wing Begonia Summer Annual ™ (Begonia x hybrida 'Dragon Wing') Partial Shade Dragon Wing Begonia is not a typical begonia. It's like a begonia on steroids' Its leaves and flowers are larger than most begonias, and its growth rate is phenomenal. It adapts well to landscape beds, containers or hanging baskets and blooms non-stop from spring until fall frost. mal manure on the planting area and incorporate it uniformly to a 12-inch depth. Then broadcast a slow-release fertilizer, such as Osmocote, over the bed according to label direclions. Space plants 12 10 18 inches apart. Mulching and thoroughly watering are the final tasks to gel the summer show under way. Soon after Dragon Wing Begonia was introduced by Pan American Like olher fibrous begonias, Dragon Wing Begonias are heavy feeders and will benefil from a liquid fertilizer, such as 20-20-20 or 15-3-15, applied each two weeks during the growing season. Seed Company in 2000, growers and landscapers from California to Florida were raving about the plant. Ahybrid cross between angel wing begonia and wax begonia, Dragon Wing Begonia offers the best qualities of both plants. It grows denser and larger than most angel wing types and has the heat tolerance of wax began ias. Dragon Wing Begonias grow 12 to 15 inches tall and 15 to 18 inches wide. Leaves are wing-shaped and large, 2 to 5 inches long, and dark glossy green. Plants tend to branch readily and grow dense without pruning. Two flower colors, red and pink, are cur rentlyavailable. The Ilowers are borne on stalks, called panicles, growing from the leaf nodes near tbe tip of each branch. Flowers sbed naturally after bloom as new ones take their place, so plants appear neat and clean all summer. In the landscape, Dragon Wing Begonia does best in filtered shade and well-drained soils enriched with organic matter. For best results, plant on a raised bed, 4 to 6 inches above the normal grade. To build up the bed, place 4 inches of compost or well-rotted ani- Dragon Wing Begonia makes a spectacular showing in the landscape when combined with tropical plants having bold foliage, sucb as bananas, cannas, gingers and tibouchinas (Princess Flower). Witb its gently arching stems and prolific, pendulous Ilower clusters, Dragon Wing Begonia also is an excellent choice for large containers. Asingle plant will fill a IO-inch hanging basket, and five plants will fill a whisky barrel, so provide plenty of room to grow. When plants grow a little to large for their container, simply trim them back to encourage new growth and flowers. When frost threatens, Dragon Wing Begonias can be cut back, dug and repotted for indoor culture and overwintering. Cuttings also can be rooted in water and potted. Give them plenty of bright Iigbt and occasional liquid feedings, and they will continue their award winning performance indoors all winter. Georgia Blue Veronica (Veronica peduncularis 'Georgia Blue') Herbaceous Perennial Hordiness Zones S to 8 Sun/Partial Shode Given Georgia's unpredictable climate, most gardeners are looking for tough, drought tolerant, heat-tolerant, and low-maintenance plants. Georgia Blue Veronica, Veronica peduncularis 'Georgia Blue', has all these qualities, and more. Georgia Blue Veronica is not another University of Georgia intro duction. In fact, it doesn't hail from the state of Georgia at all. It was found in the Republic of Georgia (formerly a part of the Soviet Union) by English plantsman Roy Lancaster, who introduced and named it after the country of origin. Georgia Blue Veronica is a herbaceous perennial with a growth habit like a groundcover and beautiful, sky-blue flowers in early spring. When planted over bulbs, such as daffodils, it provides a dramatic color contrast and spectacular floral display as it blooms in concert with the bulbs. Yellow, white and cream-colored daffodils look particularly nice against the carpet of blue. The plant is an excellent choice for container plantings and rock gardens, too, pro viding the visual appeal of a woodland stream spilling over the sides of containers or cascading over rocks. Growing just 4 to 6 inches tall and 2 feet wide, Georgia Blue Veronica tends to hug the ground and remain compact. The ever green leaves are small, about J inch long, elliplical-sbaped and finely 100thed. They're dark green in summer and turn burgundy-bronze color in winter. Gardeners who like plants that bloom over a long time will love Georgia Blue Veronica. From February to April, the plant bears an abundance of tiny, true-blue flowers with white centers. There are times during the bloom cycle that tbe foliage is literally masked by all the flowers. The flowers are highly attractive to bees and butterllies. Although Georgia Blue Veronica is a vigorous grower and spreads by creeping rootstocks, it's not aggressive or invasive. When it reaches the limits of its growing area, it can be sheared back and easily maintained within a bed. Well-drained soils and good nutrition are essential for success with Georgia Blue Veronica. Alight application of 10-10- J0 fertilizer applied every two months and watered in during the first growing season will get the plant off to a good start. Once established, a light application of a complete fertilizer, such as 16-4-8, in early spring and late summer will keep the plant looking its best. Georgia Blue Veronica can be grown from seed or propagated by dividing established planls in spring or fall. Cr.eping Rasberry (Rubus pentalobus) Groundcover Hardiness Zones 7 to 9 Most landscapes have difficult sites, like hot, dry, erodible slopes or ditches. Not many plants tolerate these conditions, but creeping raspberry, Rubus pentalobus, is one that will. In fact, it not only survives, it thrives under harsh growing conditions. Creeping Raspberry is a fast-growing evergreen ground cover imported from Taiwan. It grows 3 to 6 inches high and spreads 3 to 6 feet in all directions. As the name implies, Creeping Raspberry creeps along the ground by forming runners, much like strawberries, which root at their nodes and establish new colouies. Although it is Sun/Partial Shade aggressive, Creeping Raspberry isn't invasive. It doesn't climb trees or smother nearby shrubs, and it can be readily confined within a bed with mechanical edging. Creeping Raspberry has coarse-textured leaves with deep veins that cause them to appear puckered. They're about 1.5 inches in diame ter and have 3 to 5 lobes. During spring and summer, the leaves are shiny, dark green above and gray-green below. They turn burgundy in fall and winter. White flowers are borne in mid-summer, but they're lost in the foliage and not very showy. The flowers are 1'01 Take Home a Georgia Gold Medal Plant ... and Take Home a Winner! Prepared by Gary L. Wade, Extension Horticulturist, The University of Georgia lowed by tiny, raspberry-like fruit in late summer. Althougb the fruit are tasty and edible, they're tiny, so don't expect an abundant harvest for your breaklast table. Fruiting is not one of the plantis outstanding attributes. Plant Creeping Raspberry plants 4 to 6 feet apart to allow them plenty of room to spread. Afull- sun site is best, although plants will adapt to partial shade. Avoid planting them in wet soils or areas that may get too much irrigation. Wet soils or overhead irri gation will cause the plants to look ragged. Creeping Raspberry does well in most areas of Georgia, except in extreme mountainous regions, where winter hardiness may be a problem. It has excellent pest resistance and deer tolerance. II: after a harsh winter, the foliage looks a little rough, give it a ligbt trimming with the lawn mower in mid-March to encourage a new growth Ousb in spring. To encourage rapid establishment, apply a granular fertilizer, such as 16-4-8 or 12-4-8, in early spring. Apply fertilizer wben the foliage is dry, and use a broom or rake to get excess granules off the leaves. Then water with overhead irrigation to wash any residual fertilizer off the foliage. Creeping Raspberry can be propagated by separating a rooted runner from the motber plant. It's not just for ditches or slopes. Creeping Raspberry looks par ticularly nice when grown in a raised bed or planter and allowed to cascade over a wall or container. Rose Creek and Canyon Creek Abelias (Abelia hybrids) Shrub Hardiness Zones 6 to 9 Sun/Partial Shade During recent years, plant breeders have made great strides in developing new plants with outstanding seasonal characteristics that give them improved landscape appeal. Examples are Rose Creek and Canyon Creek Abelias, exciting new selections from the breeding program of Dr. Michael Dirr at the University of Georgia. Since their release in 2001 and 2002, respectively, these plants have earned the admiration of nurserymen, landscapers and gardeners tbrough out the United States. Rose Creek and Canyon Creek Abelias are seedling selections of Chinese Abelia, Abelia chinellse. They were open-pollinated with other abelia cultivars, so their exact parentage is unknown. Rose Creek Abelia was selected for its low mounding growth habit, crim son stem color, fragrant white Oowers and exceptionally long bloom period (May to frost). The plant grows 2 to 3 feet tall and 3 to 4 feet wide, making it an excellent choice for foundation plantings, con tainers, or low-growing hedges. Rose Creek Abelia has evergreen leaves that emerge with a pinkish cast, turn lustrous, dark green in summer, then darken to purple green in winter, giving the plant an ever-changing seasonal interest. Cluster after cluster of white, fragrant, tubular Oowers, about a half-inch long, are borne throughout tbe growing season. Below each Oower are small, light-pink, modified leaves, called the calyx, which remain on the plant after the flowers fade and provide even more pizzazz to the Ooral display. Canyon CreekAbelia is a larger plant than Rose Creek Abelia, growing 4 to 6 feel tall and wide. It's a great hedging plant and is an ideal cboice for a mixed perennial border. New leaves emerge with a coppery-pink cast that mellows to a soft yellow, then green, then rosey bronze in winter. Flowers are fragrant, tubular, light pink and are borne in clusters from May until frost. The flowers are sur rounded at tbeir base by a star-shaped, reddisb-pink calyx that per sists long after the Oowers drop, so the plant appears to have two Oower forms present at the same time throughout the season. Both abelias are drought-tolerant, deer-resistant, and are seldom bothered by pests. They also are highly attractive to butterOies and bees. Some light pruning may be required from time to time to remove lanky shoots. Otherwise, botb plants look their best wben allowed to develop a natural, informal appearance. Glowing Embers Japanese Maple (Acer pa/matum 'Glowing Embers') Tree Hardiness Zones S to 8 Sun/Partial Shade Glowing Embers is not just another Japanese maple. !tis an award-winning selection from Dr. Michael Dirris plant evaluation program at the University of Georgia, chosen for its vigorous growth rate, brilliant fall color, and adaptability to a wide variety of Southern landscape conditions. The original seedling selection from which others have been propagated can be seen at the entrance to the Callaway Building at the State Botanical Garden of Georgia in Athens. Unlike many Japanese maples that require shade and moist, organ ic soils, Glowing Embers Japanese Maple thrives in full sun and tol erates drought better than most trees in its class. However, it will not tolerate wet sites or sites where extreme Ouctuations in soil moisture are common. Good soil drainage is essential. Aptly named, Glowing Embers Japanese Maple provides a kaleido scope of color in fall as the leaves fade from green to purple, Oourescent orange, or yellow, much like the ever-changing and mes merizing embers of a wood fire. The color sequence of each leaf varies, and a single branch may display four distinctly different col ors at the same time. toothed, 2 to 3 inches long and about 3 inches wide with five dis tinct, pointed lobes. The tree has a dense canopy when in full leaf and is an excellent shade tree for residential landscapes where space is limited. Unlike other Japanese maples that are grafted onto a rootstock, Glowing Embers Japanese Maple is called a "c1ollol"selection, which means that it is propagated from cuttings and is not grafted onto a rootstock. Nurserymen refer to this as "growing on its own roots." They love this characteristic because it makes production more efficient and less time-consuming. Once established, Glowing Embers Japanese Maple will benefit from spring applications of a complete garden fertilizer, such as 16-4-8 or 12-4-8. Prune as needed to tbin branches and to develop a desired shape. Although the tree has above-average drought toler ance, be prepared to provide some supplemental irrigation during drought periods. Glowing Embers Japanese Maple is quickly becoming a highly demanded and popular plant in the nursery industry as landscape pro fessionals and borne gardeners discover its award-winning qualities. Glowing Embers Japanese Maple is a medium-size deciduous tree, growing 30 to 40 feet high with an equal spread. Leaves are finely Georgia Gold Medal Winners are selected each year by the Georgia Plant Selection (omminee, comprised of GreeA<lndustry professionals and faculty from The University of Georgia. The (omminee promotes the production, sale and use of superior ornamental plants in Georgia. For information on other Georgia Gold Medal Winners, visit www.georgiagoldmedal.com
