Catalpa grows 50 feet tall but can go to 90 feet. This short lived, coarse textured tree spreads 50 feet and tolerates hot weather. A sunny exposure and a well drained, moist, rich soil are preferred. Growth is rapid at first but slows down with age. The main ornamental feature is panicles of flowers produced in early summer. These are white with yellow and purple markings. The fruit is a long pod that can be a litter problem.
