Cladrastis lutea (Yellowwood): Ecology

Habitat:The yellowwood is a slow-growing, long-lived tree. It has a serious problem of producing narrow growth angles of the crotches, which often cause the tree to be subject to breakage in storms. Yellowwoods grow in most well-drained soils and are intolerant of waterlogged soils.

Diseases: They are susceptible to cankers, dieback, root rot and blight. Scale is the only pest associated with this tree.

Distribution: The yellowwood is a rare native tree. Its range is in the Appalachian Mountains in western North Carolina, eastern Tennessee, Arkansas and Missouri where it grows in rich, well-drained limestone soils on slopes, ridges and along streams. It is hardy in Iowa and other areas north of its range.
