Other Common Names:
The other common names for the Kentucky coffee tree are coffeetree, nicor tree and chicot.
The Kentucky coffee tree is a short-trunked tree with narrow, open crown of coarse branches and very large, twice-compound leaves. 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 give 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.
The Kentucky coffee tree is a native to bottomlands of the Eastern, Midwestern, and Central United States. It grows in bottomlands, ravines, and lower slopes of the Appalachian Mountains from western New York and western Pennsylvania, west to southern Wisconsin, and south through Kentucky, Tennessee, Arkansas, eastern Oklahoma and northern Louisiana.
The Kentucky coffee trees thrives best in full sun to partial sun and generally prefers continuously moist, rich, deep soils in full sun, but is very adaptable and urban tolerant, especially to heat, drought, very alkaline pH soils, soil compaction, and wet sites. Kentucky coffee tree does best in a well drained, rich soil with adequate moisture. However, it can tolerate normal droughts.
Fertilize with formulations that promote woody, strong growth rather than excessive foliar growth. Seed are best sown in a greenhouse as soon as it is ripe. The seed can also be sown in early spring in a greenhouse. Scarification and pre-soaking the seed for 24 hours in warm water, especially if it has been stored, will improve germination. Make sure the seed has swollen after soaking, soak it again if it has not and, if it still does not swell, try filing away some of the seed coat but be careful not to damage the embryo. As soon as they are large enough to handle, prick the seedlings out into fairly deep individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Consider giving them some protection against the cold for their first couple of winter's outdoors Root cuttings 4cm long and 1cm thick in a greenhouse in December. Plant the roots horizontally in pots. Longer, weaker branches should be pruned when young to promote a stronger structure.
The dioecious male and female flowers are in long branched clusters and are whitish in colour appearing in late spring.
