- Description
-
Winterberry is a deciduous tree that may grow 10 to 15 feet tall, but it often occurs in the wild as a shrub. The leaves are alternate with a sharply toothed margin and hairy underside. The bark is thin, smooth, and gray-brown. In spring, stalked, yellow-green flowers mature in clusters. Female specimens produce red-orange drupes that mature in the fall.
The common name comes from the red berries that provide winter interest and sometimes persist into early spring (if the birds don't eat them). Berries have a terminal black "dot" instead of a "fly" like the Rosaceae berries. To obtain beautiful berries the plants must be property cross-pollinated. Match blooming times with a male pollinator like 'Jim Dandy' or 'Southern Gentleman' by planting one male (per 10-20 females) within 50 feet of female plants.
Colonial. Dioecious: need compatible male pollinator plant to get female fruit set. Difficult to find the straight species in the trade. Male & female cvs available, as well as dwarf forms. May abort fruit in dry soil.
Fire Risk: This plant has a low flammability rating.
Insects, Diseases, or Other Plant Problems: No serious problems. Leaf spots and powdery mildew occasionally occur. Neutral to alkaline soils may cause chlorosis (yellowing of leaves) and even death.
