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. […]

‘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 […]

Posted by Hugh on September 26th, 2011
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 […]

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 […]

Posted by Hugh on September 19th, 2011
Some gardeners call them “Christmas peppers”. In the late summer garden all eyes turn away from most flowering annuals and to the colorful fruits of ornamental peppers (Capsicum annuum). Many are dwarf red hot chili peppers. (No!…not the rock band). Fruits are cylindrical or ball shaped and the brilliant colors range from white, yellow, […]

Posted by Hugh on September 7th, 2011
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 1st, 2011
Autumn Bride heuchera (Heuchera villosa ‘Autumn Bride’) is blooming now. This native ground cover, aka “hairy alumroot”, displays wide lime-green foliage which is not as colorful as many new H. villosa hybrids introduced in recent years. However, the white flowers on Autumn Bride are showier and more numerous. Heucheras prefer a moist, well-drained, compost-rich soil. Plants are heat and humidity […]
Gaillardia Survival Depends On Winter Soil Drainage
Posted by Hugh on August 29th, 2011
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! Soggy winter clay soil is their […]

Posted by Hugh on August 26th, 2011
Sunpatiens™ live up to all their hype, with a caveat. They are still impatiens, which means they love (and can’t go without) water. In the Southern Appalachian region (USDA zones 6 and 7), Sunpatiens prosper in direct full day sun to part shade, but can’t go without weekly watering. The flower bed should be mulched […]

Posted by Hugh on August 23rd, 2011
Chinese (Kousa) dogwood (Cornus kousa) rates four stars (out of four) as a beautiful small flowering landscape tree. Since the 1970’s, a deadly anthracnose (Discula spp.) fungus disease has threatened to eradicate our native flowering dogwood (C. florida). Kousa dogwood rates as a highly disease resistant alternative. Its Achilees’ heel is its less than stellar foliar heat […]
