Description

Growth Forms:

Worldwide, they are found as shrubs or trees, however, the one representative species in California (Aesculus californica) is a tree.

Branching:

Opposite

Leaves:

Palmately compound

Flowers:

Flowers are often showy, in panicles or racemes. Although buckeye flowers are very attractive to bees, they are wind pollinated.

Fruit:

Buckeye seeds are large and heavy, between 1 and 2 inches across. The seeds ripen in October or November.

Growing Conditions

Shade Tolerance:

Buckeyes are intolerant of shade.

Soil and Moisture:

Buckeyes prefer moist but not wet soil and are often found in or adjoining riparian zones. Occasionally, however, they may be found in fairly dry sites.

Horticulture and Restoration

Wildlife Habitat:

Habitat value is somewhat limited. The seeds and pollen are poisonous to some species of insects and mammals. Also the mid-summer leaf drop limits their usefulness for animal cover.

Restoration Projects:

Aesculus californica is often used in riparian woodland restoration projects.
