Better Red Fall Leaf Color On American Hornbeam

American hornbeam (Carpinus caroliniana), aka ironwood or muscle wood, grows primarily in moist, slightly acidic soils along woodland rivers and streams (USDA hardiness zones 3-9).

ShiShi Gashira Camellia So Far Holding Up to Zone 6-b Winters

Camellias bloom at a time when most trees and shrubs are not flowering. Growing them is no longer a dream for gardeners who do not live in the deep South. A number of “designated zone 6 hardy” cultivars prosper in the Southern Appalachian region (USDA hardiness zones 6 and 7). ‘ShiShi Gashira’ camellia (Camellia hiemalis) […]

Three New Hardy Fall Blooming Camellias

A recent visit to a local camellia grower found these three fall bloomers: ‘Long Island Pink’, ‘Londontowne Blush’, and ‘Sweet October’ in full floral regalia. The first two are reliably hardy in USDA zone 6 and a third nearly so. ‘Long Island Pink’ was found […]

‘Halloween Hocus Pocus’ Daylily For Garden Goblins

On a pleasant July morning I saw my first ‘Halloween Hocus Pocus’ daylily (Hemerocallus x ‘Hocus Pocus’) in a friend’s garden. The 5 ½ inch flowers stand on 26 inch tall stems (scapes) and the foliage is semi-evergreen. The cultivar name describes it best. Its creamy orange color with a triangular black throat and wide […]

Beautyberry Deservedly Becoming More Popular

The stunning purple berries of beautyberry (Callicarpa spp.) are eye-catching in late summer. White fruited varieties are also sold, but the purple forms are most popular. This 6-8 foot shrub has medium green, 3-5 inch long foliage spring thru summer. Autumn leaf color adds little, the deciduous leaves turning purple to pale yellow, shriveling, and abcising. The purple fruit clusters are electifying, perhaps […]

Better Blackberry Varieties Available

Growing Blackberries Blackberries (Rubus spp.) are among the easiest fruit crops to grow in the Southern Appalachian region (USDA hardiness zones 5 and 7), but are not as hardy as raspberries. A blackberry planting has a productive life between 8-10 years. A sturdy trellis system, composed of strong posts and wire, will make harvest chores […]

Aster ‘Raydon’s Favorite’ Is Spectacular Autumn Bloomer

Aster Raydon’s Favorite (Symphyotrichum oblongifolium ‘Raydon’s Favorite’) is one of our most reliable native perennial asters. This aromatic aster blooms in mid-autumn, covered with 1 ½ inch wide blue-purple daisy-like flowers with yellow centers. Butterflies and bumble bees are frequent visitors to this aster in my October garden. Night temps in the mid-twenties don’t injure […]
