Possum Haw

Ilex decidua
Aquifoliaceae (hollies)

Usually a shrub with a spreading, open crown; sometimes a small tree. Eye-catching in fall and winter with bright red berries.

Leaves simple, alternate or in clusters on short spurs; 2–3 inches long, widest at the middle and tapering at both ends. Tip blunt, margin mostly with round or blunt teeth.

Bark smooth, thin, mottled gray to brown, sometimes with numerous warty protuberances.

Twigs drawn out, slender, often with many short spurlike lateral twigs, light to dark gray.

Flowers April–May. Some plants may be male, others female, or flowers may be perfect (containing both male and female parts). Petals 4–6, white, egg-shaped; stamens 4–6.

Fruits September–October. Globe-shaped berry; orange to red; ¼ inch across; solitary or 2 or 3 together; seeds usually 4, pale yellow. Berries persistent on branches most of the winter after leaves are shed. As with other hollies, only female trees produce berries.

Height: to 30 feet; generally smaller (as a shrub).
Habitat and conservation: 
Possum haw is the more common of two native Missouri hollies that lose their leaves each fall. Occurs in a variety of wet or dry habitats throughout the Ozarks and southeastern lowlands, but it is absent from much of northern Missouri. Dolomite glades, rocky upland open woods, fencerows, borders of upland and lowland ponds, swamps, sloughs, valleys and low, wet woods along streams.
Distribution in Missouri: 
Ozarks, Mississippi Lowlands, and in counties bordering the Mississippi River. Statewide as an ornamental.
Human connections: 
Occasionally planted as an ornamental and for its value in attracting birds and other wildlife. As with other hollies, only the female plants will bear fruits, and these require the presence of a male plant. Thus to have a possum haw with berries, you will need at least two plants.
Ecosystem connections: 
Many species of birds and mammals eat the berries, and deer browse the twigs. The bright red berries seem to be ignored by wildlife for months but eventually are consumed later in winter as either their taste improves or other wild fruits become scarcer.
