Description

Ilex verticillata, commonly called winterberry, is a deciduous holly that is native to eastern North America where it typically occurs in swamps, damp thickets, low woods and along ponds and streams. This is a slow-growing, deciduous shrub with an upright-rounded habit that typically grows 3-12’ tall. In the wild, it often suckers to form large thickets or colonies.  This plant is slightly salt tolerant.

The common name comes from the quite showy berries that are showy all winter and sometimes into early spring.  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.

Insects, Diseases, or Other Plant Problems:   Occasional disease problems include leaf spots and powdery mildew. Plants do poorly in neutral to alkaline soils where they are susceptible to chlorosis (yellowing of leaves) and often die.
