Autumn Colors Conclude with Callery Pears
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 […]

Posted by Hugh on November 12th, 2011
Among dwarf conifer collectors, ‘Morgan’ Oriental arborvitae (Platycladus orientalis) has become one of the most sought out evergreens over the past decade. Its oval form and seasonal coloration makes Morgan a standout. It performs well in part sun, but its chartreuse-yellow foliage appears more vibrant in direct sunlight. Its dense foliage grows in vertical layers. Andy Pulte at the […]

Natural Evergreen Needle Drop in Autumn
Posted by Hugh on October 25th, 2011
Some needle loss on evergreens in the fall is natural. As night time temperatures cool, needles in the interior of many evergreen trees or shrubs regularly turn brown (or golden yellow) and drop off. Needle loss is most obvious on pines (Pinus spp.) and arborvitae (Thuja spp.) in the Southern Appalachian region (USDA zones 6 and 7). The […]

Autumn foliage color is upon us in the Southern Appalachian region (USDA zones 6 and 7).

Virginia creeper foliage peaks 2 to 3 weeks ahead of most woodland trees and shrubs. Lots of gardeners […]

‘Little Lemon’ Goldenrod Acts Like Late Summer Bedding Plant
Posted by Hugh on September 29th, 2011
Across the Southern Appalachian region (USDA zones 6 and 7), the native goldenrods (Solidago spp.) are easy to spot, growing 6-8 feet tall in ditch banks along roadsides and in the poorest of soils. Over the past quarter century short, more compact cultivars have arrived local garden centers. ‘Little Lemon’ grows only 12-15 inches tall with a 18-24 inch spread. This diminutive […]

I thank the person who gave me a native swamp sunflower (Helianthus angustifolia). This long-lived perennial appears to have its own internal clock for blooming around the first day of October. Its long narrow rough-textured leaves average 6 inches in length. The 2-3 inch wide flowers appear first on top of the tall 6 to 7 foot plants, and […]
