Winterberry Holly Profile for Maryland

Compare winterberry holly's Maryland wetland range, moist acidic soil, light, mature size, and male-pollinator needs for fruit.

Winterberry holly (Ilex verticillata) is a deciduous shrub associated with Maryland wetlands across the Mountain, Piedmont, and Coastal Plain regions in University of Maryland Extension’s profile. Confirm local range and stock before planting; a wetland association does not mean a shrub tolerates permanent ponding at every site.

Site profile

Field Source description
Mature size About 6–12 feet; some cultivars reach about 4–6 feet.
Light Full sun to mostly shade.
Soil Moist, high-organic soil; any texture; acidic pH 4.5–6.5.
Fruit Female plants produce berries when pollinated by a male of the same species. Overlapping bloom improves fruiting. UMD gives one male for up to 10 female plants within 50 feet as its planting guidance.
Water limit The profile does not give a permanent-ponding threshold or flood duration.

Schematic of one male winterberry with up to ten female plants within 50 feet; overlapping bloom improves fruiting, but the arrangement does not guarantee fruit set.

UMD’s count and distance are planting guidance, not a fruit-set guarantee or a placement plan.

Choose winterberry for a site that fits the source’s moist-soil description and the shrub’s mature size. If fruit is the goal, track plant sex and bloom overlap when selecting stock; the cited spacing is UMD guidance, not a guarantee of fruit set under every site condition.
