Family: Fabaceae, Pea view all from this family



Description When crowded by other trees, this species grows tall and slender. If more open-grown, it becomes a round-topped tree. Its unique bark is dark brown and roughened with scale-like ridges in distinct patterns. It leafs out late in spring. The large, twice-compound leaves gives the foliage a tropical look. Greenish-white flowers are held in terminal clusters, and the fruit is a purplish-brown pod that remains into winter. Fall foliage is yellow-green. Kentucky coffeetree grows 75-100 ft. tall.


Warning Raw seeds are poisonous and can be fatal to humans and animals. Sensitivity to a toxin varies with a personís age, weight, physical condition, and individual susceptibility. Children are most vulnerable because of their curiosity and small size. Toxicity can vary in a plant according to season, the plantís different parts, and its stage of growth; and plants can absorb toxic substances, such as herbicides, pesticides, and pollutants from the water, air, and soil.
