Also known as Cigar tree and Indian Bean, this is a perennial, ornamental tree, growing 30 to 60 feet tall with a 20 to 40-foot spread in partial shade and moist to wet soils. Its showy flowers, white with purple and yellow markings, appear in late spring and early summer, and are attractive to hummingbirds. Catalpas host the Catalpa sphinx caterpillar, an important food for cuckoos as well as both Swallow-tailed and Mississippi Kites.
