Report an issue with this species

Cladrastis kentukea, or Kentucky yellowwood, is a deciduous tree native to the Southeastern United States, recognized by its open, rounded canopy of broad, feathery leaves that turn yellow in fall. It produces fragrant white flowers in late spring and is notable for its smooth gray bark. While drought tolerant once established, its brittle branches require protection from strong winds.
