CATALPA

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

Native to central U.S., this tree grows to 40–60 ft. tall, 20 to 40 ft. wide. Heart-shaped leaves are 6–12 in. long and odorless when crushed. Fewer flowers per cluster than for C. bignonioides.
