Most artemisias (aka “wormwood”) can not cope with the summer heat and humidity in the mid-South. Their silvery foliage tends to burn out (some say “melt out”) in mid to late summer. ‘Powis Castle’ artemisia is truly the exception. Powis Castle is likely a hybrid (Artemisia arborescens x A. absinthium Powis Castle is a bushy, woody-based perennial […]

Rhododendrons (Rhododendron catawbiense) were born in the cool of the North Carolina and Tennessee mountains. Hundreds of lovely hybrids have been bred by dedicated plantsmen. Winter hardiness is rarely an issue, but rhododendrons are challenged by summer heat and disease problems in the Southern Appalachian region (USDA hardiness zones 6 and 7).

A few years back my church pastor complained about the ugly load of seed pods covering the redbud branches (Cercis canadensis) on the property in the fall.

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 […]
