Establishment
First 1-2 yearsYoung plant focuses on root development with sparse branching and minimal growth above ground
Water regularly, protect from harsh winds, apply 2-3 inches of mulch around base (keeping away from stem)
Vegetative Growth
Years 2-4Plant develops fuller branching structure with bright green deciduous leaves and increased height
Continue regular watering, light pruning to shape, fertilize lightly in spring if needed
Flowering
Late May to JuneSmall whitish-green flowers appear in clusters on new growth in late spring
Ensure male plants are nearby for pollination; do not prune heavily during this period to maintain flower production
Fruiting
July through February of following yearBright red to orange berries develop after flowering, growing larger through summer and persisting after leaf drop
Avoid excessive fertilizing which reduces berry production; ensure female plants present for fruit set
Dormancy
November through MarchLeaves drop in fall revealing bare branches laden with brilliant red berries
Minimal care needed; berries attract wildlife; prune only to remove dead wood or shape as needed

Fun Facts
- 🌱 Possumhaw is one of the few deciduous hollies native to North America and gets its common name because opossums relish the berries, often visiting trees during winter foraging.
- 🌱 The plant is dioecious, meaning separate male and female plants are needed for berry production; female plants produce the showy berries while male plants provide pollen.
- 🌱 Possumhaw berries can remain on branches for months, actually becoming more attractive to birds as the winter progresses and other food becomes scarce, making it a critical winter survival resource.
