Kentucky Coffee Tree
This very rough, coarsely branched tree usually grows to a height of 40-70 feet with a trunk diameter of 3 feet. The bark is very rough. The leaves are doubly compound, with about 9 broad oval-shaped leaflets that are pointed and toothless. They are alternate and there is a pair of single leaflets on the base of the main stalk. There are male and female trees, which produce their flowers in white, nodding clusters, and bloom in May to June. The fruit is a broad, leathery, dark brown pod, 4-9 inches long, pulpy inside with 6-8 seeds, and pods persist in the winter. The seeds at one time were used as a substitute for coffee and were called coffee-nuts. The seeds are actually toxic unless boiled thoroughly.

Family Fabaceae (Leguminosae) The Fabaceae, or Legumes, are mostly herbs but include also shrubs and trees found in both temperate and tropical areas. They comprise one of the largest families of flowering plants, numbering some 400 genera and 10,000 species.

Gymnocladus dioica means "naked branch." This tree spends about 6 months of the year without leaves. When the doubly compound leaves appear in late spring, they are very large, up to one meter long and 60 cm wide.

A legume, the Coffeetree produces long, dark brown leathery pods that contain up to seven rounded, dark, hard-coated seeds. The Kentucky Coffeetree prefers sunny locales in rich woodlands and at the edges of marshes. However, it tolerates a wide variety of growing conditions in full sun.
