Any tree of the genus Catalpa, in the family Bignoniaceae. The two North American species, the southern catalpa, Catalpa bignonioides, and the northern catalpa, Catalpa speciosa — along with the yellow catalpa, Catalpa ovata, from China — are often planted as ornamentals because of their showy flowers and decorative bean pods, though others regard the bean pods as a nuisance.
