Re-blooming is an unusual plant trait. Selected cultivars return this time of year for a repeat floral show. In my garden Encore™ azaleas (Rhododendron spp.), re-blooming irises (Iris spp.), and re-blooming daylilies (Hemerocallis spp.) are back for second round of flowering in late summer and early fall. The gardener/landscaper must supply needed soil moisture and nutrition (primarily nitrogen) so that plants don’t struggle […]

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 […]

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 […]

Kingwood Center is a wonderful public garden in Mansfield, Ohio with several top notch beds of hostas. One glorious bed of ‘Royal Standard’ hosta blooms their heads off from mid-August into September. With over 35,000 registered hostas available, why look back at this vintage variety.

Kim Hawkes, former owner of Niche Gardens Nursery in Chapel Hill, N.C. introduced compact growing ‘Kim’s Knee High’ a decade ago. It is still one of the finest cultivars. ‘Kim’s Knee High’ […]

They are mostly black, except for a yellowish brown spot on their thorax, and their smoky wings. The pale green larvae mature to 1/2 inch in length. The larvae […]

Depending on where you garden, Canna lily (Canna spp.) is a tropical-looking, herbaceous annual or perennial. Its colorful foliage and long blooming time leaves a huge visual impact. Canna is not reliably winter hardy in the Southern Appalachian region (USDA hardiness zones 6 and 7). […]

For nearly half a century, ‘Autumn Joy’ has been the leading “stonecrop” or “live forever” sedum cultivar planted. More than once I’ve heard this saying: “if Autumn Joy won’t grow in your garden, you should try another hobby. ‘T-Rex’ is a terrific new hybrid and ‘Autumn Joy’ is one of its parents. ‘T Rex’ has […]
