There are so many fine redbuds (Cercis spp.) which are hardy in the Southern Appalachian region (USDA zones 6 and 7) and elsewhere. Through research and breeding efforts at the JC Raulston Arboretum in Raleigh, NC, Southeast U.S. gardeners can grow several more cultivars of our native Eastern redbud (C. canadensis and subspecies texensis) and […]

Comments Off on Evaluating The Weeping RedbudsPowis Castle Artemisia Is Exceptional
Posted by Hugh on March 16th, 2012
Most artemisias (aka “wormwood”) can not cope with the summer heat and humidity in the mid-South. Their silvery foliage tends to burn out (some say “melt out”) in mid to late summer. ‘Powis Castle’ artemisia is truly the exception. Powis Castle is likely a hybrid (Artemisia arborescens x A. absinthium Powis Castle is a bushy, woody-based perennial […]

Japanese barberry (Berberis thunbergii) is a very popular landscape shrub. Japanese barberry is indigenous to Eastern Europe and Asia and is commonly planted in USDA hardiness zones 4-8. There is justified concern over the invasive nature of Japanese barberry. A number of states have declared most barberry species (Berberis spp.) to be invasive and have […]

Posted by Hugh on February 27th, 2012
A few years back my church pastor complained about the ugly load of seed pods covering the redbud branches (Cercis canadensis) on the property in the fall. My suggestion to avoid messy seed pods is to plant seedless redbud cultivars. A number of native redbud (C. canadensis) cultivars produce few to no seed pods. Let’s start with the cultivars ‘Ace of Hearts’ and sister seedling ‘Little […]

Posted by Hugh on February 16th, 2012
Parrotia (Parrotia persica), aka “Persian ironwood”, is native to Iran, Turkey, and the Caucasus region. Parrotia forms a lovely carefree medium sized lawn or street tree. Tree framework is vase-shaped, initially narrow at the base and flaring out in the canopy as it ages. Mature tree height varies 25-40 feet, depending on location and the seedling or cultivar planted. Rated hardy in USDA […]

Vernal witchhazel (H. vernalis) is a dense growing 8-12 foot native shrub which blooms in mid-winter in the Southern Appalachian region (USDA zones 6 and 7). It is winter hardy to zone 4. Small ½ inch wide yellow to red flowers, flushed red at the base, emit a pleasant witchhazel aroma in February. Often, it is the […]

Posted by Hugh on January 26th, 2012
Dawn redwood (Metasequoia glyptostroboides) was thought to be extinct for the past 20 million years. Since 1948 gardeners have witnessed its re-introduction back into the North American landscape from Sichuan-Hubei Provinces in China where the tree was re-discovered. Dawn redwood prefers a well-drained, compost-rich, acidic soil. This deciduous conifer tolerates standing water for a brief 2-3 day span, not as long as bald cypress […]

Posted by Hugh on January 12th, 2012
Little King, aka Fox Valley™, (Betula nigra ‘Little King’) is a 10-12 foot tall shrubby river birch, which fits into small landscapes. Simple minimal pruning can shape it into a lovely small tree. Little King possesses the desirable traits of large river birches, including an oft-white exfoliating bark. River birch exhibits good heat tolerance in the Southeastern U.S. (USDA zones 4-8) and has […]

Posted by Hugh on December 17th, 2011
There are over 200 species of prickly pear cactus (Opuntia spp.) worldwide. Several make great container plants in the garden or inside the home. Prickly pear cacti may grow to heights of 10 feet or more in the arid regions of the Southwestern U.S. Eastern prickly pear (Opuntia compressa var. ‘humifusa’) grows 12- 18 inches tall and 30-36 inches wide.

Posted by Hugh on November 23rd, 2011
Callery pear (Pyrus calleryana) has been declining in planting popularity. But its scarlet red leaf color is both sensational and reliable every autumn in the Southern Appalachian region (USDA zones 6 and 7). Most people identify the tree by its cultivar name, e.g. ‘Bradford’, Aristocrat®, ‘Cleveland Select’, ‘Redspire’ pear. There are many other cultivars. Callery pears are tough reliable medium sized trees which […]
