Kentucky Coffeetree

Gymnocladus dioicus

Kentucky Coffeetree (Gymnocladus dioicus) is a landscape plant valued for its form and structure as much as its bloom. It reaches roughly 100 ft at maturity and blooms in early summer. Match it to full sun to part shade and water on a normal schedule until it is established. One caveat worth knowing before you plant: parts of this species carry a toxicity flag (high), so keep it away from pets and kids who chew on landscape plants. Given a spot that matches its light and water needs, it is a dependable, low-drama addition to the yard.
