‘Sunsphere’ Japanese Cornel

  Japanese cornel (Cornus officinalis) is a tall shrub or small tree dogwood which matures to 20-25 feet in height and 15 feet in width. ‘Sunsphere’ Japanese cornel was discovered by Mike Stansberry, owner of  Beaver Creek Nursery in Knoxville, TN. Japanese cornel is the official start of spring in my garden, even though the calendar reads late […]

Edgeworthia Deserves A Try

Edgeworthia flowering in March garden First, I must thank South Carolina nurseryman, Mr. Ted Stephens, who gifted me  a Chinese paperbush (Edgeworthia chrysantha) nearly 6 years ago. Most plant authorities rate its winter hardiness to USDA zones 7 and 8. It struggled through its first winter and spring  in my zone 6-b garden, but has never disappointed. […]

Opening Show in February- The Witchhazels

First, not to confuse you, our North American native witchhazel (Hamamelis virginiana) blooms in the fall. Our native vernal witchhazel (H. vernalis) has been flowering for the past few weeks. In February, the showiest witchhazels are opening now – species from China, Korea and Japan. Two of the very best are a Chinese species/cultivar called […]

Crabapple Shopping List

For those of you tired of the monotony of Bradford pears, go shopping for ornamental crabapples (Malus spp.). Most crabapple cultivars mature into long-lived small flowering trees less than 20 feet in height at maturity. Most fit under utility lines. Worldwide, there are over 400 cultivars of crabapples in nursery commerce. Most are susceptibility to […]

Two Sensational New Oakleaf Hydrangeas

Oakleaf hydrangea (Hydrangea quercifolia) is a popular native shrub in the Southeastern U.S. (USDA hardiness zones 5 to 8). Two new compact forms of oakleaf hydrangea were recently introduced by the U.S. National Arboretum. In early summer, ‘Ruby Slippers’ is covered with 9-inch-long floral clusters that are held upright above the foliage. ‘Ruby Slippers’ grows […]

Stop the Leyland Madness

Leyland cypress (x Cupressocyparis leylandii) is a tall, fast growing evergreen tree or shrub. Many are planted as privacy screens. Ask yourself, should you really plant a 50 foot barrier between you and your neighbor(s)?  In the Southern Appalachian region (USDA hardiness zones 6 and 7), there are shorter and better evergreen choices. In the 12-16 foot category: Boxwood (Buxus […]

Planting Trees for Future Generations

Oaks, beeches, hickories, ginkgoes, bald cypresses, redwoods, chestnuts and others are trees that future generations inherit from previous generations. In human terms, it takes a lifetime to grow an acorn into a mighty oak. Many tree species live hundreds of years, often asking little and contributing much beauty, summer cooling shade, winter heating comfort as windbreaks, and a […]

Hardy Dwarf Deodara Cedars

Over the past ten years, deodara cedar (Cedrus deodara) has carved its niche into Southern Appalachian gardens (USDA zones 6 and 7). Three zone 6 hardy dwarf cultivars, ‘Glacier Blue’, ‘Devinely Blue’, and ‘Feelin Blue’, fit  today’s smaller garden space better than most tree forms of deodara cedar that typically reach 70-80 feet in height. […]

Winter King Hawthorn – A Winter Fruit Attraction

bright red fruit in winter season ‘Winter King’ is an outstanding cultivar of our native green hawthorn (Crataegus viridis) and is at home here in the Southern Appalachian region (USDA zones 6 and 7). Over the winter season few deciduous trees present a colorful fruiting display much better than Winter King. Winter King hawthorn is a small landscape tree, maturing to 25-30 […]

Hardy Camellias — start with this one!

Occasionally, gardeners need abit of confidence before purchasing a plant considered not winter hardy where they live. Twenty years ago, growing a camellia was a folly inside the Southern Appalachian region (USDA zones 6 and 7), until the Drs. Ackerman and Parks’ introductions appeared. These hardy cultivars have changed the playing field. Recently, I asked some local camellia “experts”  what one favorite cultivar gardeners […]
