- Description
-
Possumhaw is a deciduous holly that is commonly called possumhaw. It can be found on limestone glades and bluffs, along streams in wet woods, and in lowland valleys, sloughs and swamps. It is an upright shrub or small tree with a spreading, rounded crown which typically grows 7-15' tall in cultivation (to 30' in the wild). Its bark is gray-brown and smooth with occasional warts. Birds, deer and a variety of small mammals (including opossums as the common name suggests) are attracted to the fruit. Plants of this species are mostly dioecious (separate male and female plants), but some plants have perfect flowers (complete flowers with functioning stamens and pistils). For best show of berries, plant female plants, with at least one male plant to insure that pollination will take place. Prune to shape in early spring just before new growth begins.
Dioecious: need male pollinator plant to get female fruit set.
Fire Risk:
This plant has a low flammability rating.
Insects, Diseases, or Other Plant Problems:
The Possumhaw holly will occasionally incur problems that include leaf spots and powdery mildew.
Th Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common diseases and insect pests.
