American Yellowwood is a beautiful native tree that should be used in more landscapes. The flowers are very fragrant, with lovely white pea-shaped flowers appearing in May and June on long pendulous panicles. They provide excellent food for bees and other insects, and they resemble a more refined Wisteria flower. The foliage emerges in spring as a chartreuse green during the summer, finishing up as a bright yellow in fall. The bark is an attractive grayish brown, very smooth textured and closely resembling Beech bark. Cladrastis kentukea tolerates both acidic and alkaline soils, and prefers adequate moisture.
