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 […]

Posted by Hugh on October 10th, 2011
Autumn foliage color is upon us in the Southern Appalachian region (USDA zones 6 and 7). On a weekend drive through the Smoky Mountains, vivid red Virginia creeper (Parthenocissus quinquefolia) foliage draped highway fences and tree branches. Virginia creeper foliage peaks 2 to 3 weeks ahead of most woodland trees and shrubs. Lots of gardeners […]

Posted by Hugh on October 7th, 2011
The cultivar Diabolo ninebark (Physocarpus opulifolius ‘Diabolo’) is an aggressive grower. A knowledgeable gardener with a sharp pair of pruners may quickly and easily train Diabolo ninebark into a small tree. Plant a ninebark tree in a large container for multi-seasonal color around your deck or patio. Its common plant name “ninebark” says a lot. […]
Plant Autumn Asters Instead Of Mums
Posted by Hugh on October 2nd, 2011
Aromatic asters (Aster oblongifolius) is one of our finest late blooming native asters for the autumn garden in the Southern Appalachian region (USDA zones 6 and 7). Through the spring and summer months, the dense gray-green shrubby foliage mounds grow 15-18 inches high and 24-30 inches wide. Hundreds of yellow-centered, daisy type flowers cover the […]

Franklinia (Franklinia altamaha) is admittedly a very finicky large shrub or small tree. Pure white, five-petal, 2 ½ – 3 inch camellia-like flowers bloom sporadically from August thru mid-October. Flowers are slightly fragrant. In the fall glossy green leaves gradually transition to blends of red, orange and burgundy hues. Franklinia grows best on an eastern exposure […]

White Snakeroot (Eupatorium rugosum) is native to moist woodland areas in most eastern and midwestern states (U.S.). It grows in average, moist, well-drained soil in full sun to light shade. It is a long-lived and an aggressive perennial. ‘Chocolate’ (E. rugosum ‘Chocolate’) earns its namesake for its chocolaty or burgundy tinted foliage. ‘Chocolate’ white […]

Posted by Hugh on September 4th, 2011
Sweetgum (Liquidambar styraciflua) is a medium to large landscape tree, which matures to 65-70 feet in height and 35 feet in spread. To many people it’s called the cursed “gumball” or “ankle twister” tree, not be confused with the fruit balls of the American sycamore or London plane tree (Platanus spp.). Gumball detractors should look […]

In recent years several hybrid cultivars of blanket flowers (Gaillardia x grandflora) have been introduced. Some are annuals and others perennials. This North American prairie native is hardy in USDA zone 5 hardy. Gaillardias should thrive in the Southern Appalachian region (USDA zones 6 and 7), but they don’t!

On hot clammy August days, towering 6-8 feet in height, there is Joe-Pye* weed (Eupatorium purpureum) to enjoy. It is visually hard to miss when driving along rural roads in the Southern Appalachian region (USDA zones 6 and 7). Joe-Pye’s flowering sends me a timely message that autumn is only six weeks away. For gardens the cultivar […]

It’s late summer in the Southern Appalachian region (USDA zones 6 and 7). Outdoor temperatures continue to hit 90°F almost daily, and weekly precipitation is low.
