Content Detail

Commonly called Osage-orange or hedge apple, this medium-sized tree has a short trunk and rounded crown with large globular fruit produced by female trees. Osage-orange produces large fruit, tends to have an aggressive nature, and is considered invasive in some areas of the United States.

Size and form:

Osage-orange mature height and width is 20 to 40 feet with thorns that are especially ferocious on new growth.

Native geographic location and habitat:

It is native to the southern United States.

Attracts birds, pollinators, or wildlife:

Small mammals are attracted to it.

Bark color and texture:

The gray-brown to orange-brown bark is distinctly furrowed into an irregular criss-cross pattern. The bark has a somewhat fibrous appearance. It has thorns which can be particularly prickly on new shoots.

Leaf or needle arrangement, size, shape, texture, and color:

The simple, alternate leaves are egg-shaped and 2 to 5 inches long with the margin being untoothed. Leaves are medium green in summer and change to yellow-green or yellow in fall.

Flower arrangement, shape, and size:

Male and female flowers are on separate trees (dioecious) in round clusters, but are ornamentally unimportant.

Fruit, cone, nut, and seed descriptions:

The fruits are large, 4 to 6 inch diameter, ball-like structures. They are yellow-green in color and have a surface pattern that resembles that of a brain.

Plant care:

This is a very tough species that can withstand many different soils and environments once established. Female trees need a male tree pollinator in order to produce fruit. Osage-orange suckers freely and with its thorns can quickly form an impenetrable barrier.

List of pests, diseases and tolerances:

No serious pest problems. The stems can be thorny.

White Shield osage-orange (Maclura pomifera ‘White Shield’):

A fruitless cultivar that has few to no thorns. It grows 35 feet high and wide, is fast-growing, and produces yellow fall color.
