Scientific Name
Ilex decidua
Aquifoliaceae (hollies)

Possum haw, or deciduous holly, is usually a shrub with a spreading, open crown; it is sometimes a small tree. It is eye-catching in fall and winter with bright red berries.

Leaves are 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 is smooth, thin, mottled gray to brown, sometimes with numerous warty protuberances.

Twigs are 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.

Similar species: Missouri has 4 species in genus Ilex. Of the two native Missouri hollies that lose their leaves each fall, possum haw is the one that is more common. Our other deciduous holly species is winterberry (I. verticillata). It is rare in Missouri; within our state, natural populations occur only along igneous shut-ins, rocky streambeds, and sandstone bluffs of the St. Francois Mountains. It has generally larger leaves that are wider toward the base, have more sharply toothed margins, and have downy undersides. It is typically smaller than possum haw.


Height: to 30 feet; generally smaller (as a shrub).

Where To Find

Ozarks, Mississippi Lowlands, and in counties bordering the Mississippi River. Planted statewide as an ornamental.

Possum haw occurs in a variety of wet or dry habitats throughout the Ozarks and southeastern lowlands, but it is absent from much of northern Missouri. It prefers dolomite glades, rocky upland open woods, fencerows, borders of upland and lowland ponds, swamps, sloughs, valleys, and low, wet woods along streams.

Native Missouri shrub or small tree. Very popular native landscaping plant, offering ornamental and wildlife value.

Very popular as a native landscaping shrub, 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.

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.

About Trees, Shrubs and Woody Vines in Missouri
There are no sharp dividing lines between trees, shrubs, and woody vines, or even between woody and nonwoody plants. “Wood” is a type of tissue made of cellulose and lignin that many plants develop as they mature — whether they are “woody” or not. Trees are woody plants over 13 feet tall with a single trunk. Shrubs are less than 13 feet tall, with multiple stems. Vines require support or else sprawl over the ground.
