It grows in average well-drained acidic or mildly alkaline soil and thrives either in full or partial (6 hours) sunlight. Contorted filbert is usually sold in a grafted form. It is also called corkscrew hazelnut because most branches, twigs and leaves display […]

Posted by Hugh on March 21st, 2012
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 […]

Holly Tea Olive (Osmanthus spp.) comprises a number of evergreen shrubs from Japan which are winter hardy in USDA zone 7- 9. ‘Goshiki’ (O. heterophyllus ‘Goshiki’) is a hardier compact evergreen shrub, which grows very slowly at 3-4 inches per year. It is long-lived, maturing to 5- 6 feet in height and 5 to 7 […]

Posted by Hugh on March 11th, 2012
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 March 8th, 2012
Crabgrass is an annual grassy weed which dies out around the first autumn frost. Seeds dropped last summer germinate when the soil warms up from early spring through summer. When spring soil temperatures reach 55-60 degrees (the forsythia shrub is blooming), apply a pre-emergent crabgrass preventative. These herbicides are very effective applied in late winter […]

Posted by Hugh on March 2nd, 2012
Rhododendrons (Rhododendron catawbiense) were born in the cool of the North Carolina and Tennessee mountains. Hundreds of lovely hybrids have been bred by dedicated plantsmen. Winter hardiness is rarely an issue, but rhododendrons are challenged by summer heat and disease problems in the Southern Appalachian region (USDA hardiness zones 6 and 7). Your most important decision is […]

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 […]
