Catalpas are among the few hardy deciduous trees that can compete in flower and leaf with subtropical species. Large, upright clusters of trumpet-shaped, 2-in. wide flowers are pure white, with stripes and markings in yellow and soft brown. These are displayed in late spring and summer above large, bold, heart-shaped leaves. Flowers are followed by long, bean-shaped seed capsules sometimes called “Indian beans.”Catalpa speciosa
