- 7-30 ft.
- Flower:
- The whitish flowers of both male and female Possumhaw holly are relatively inconspicuous. Pollinated female flowers give way to orange-red berries which ripen in September and persist throughout the winter until mid-March when new growth begins. Birds, deer and a variety of small mammals (including opossums as the common name suggests) are attracted to the fruit.

- Habit:
- Deciduous
- Site:
- The Possumhaw holly is easily grown in average, medium moisture soil in full sun to part shade. It is adaptable to both light and heavy soils, but prefers moist, acidic, organic soils. Does have some tolerance for wet conditions. 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.
