Catalpa is an old American Indian name for the plant. Southern catalpa is a U.S. native short-trunked tree with a rounded to irregular form that can reach 30 to 40 feet in height. When flowering it has abundant showy blossoms, attracts insect pollinators. Attractive, large panicles of white bell-shaped flowers with yellow and purple spots bloom in early summer and are long-lasting. Native to floodplains, southern catalpa is very adaptable and tolerant of adverse conditions.
Southern catalpa is native to Alabama, Georgia, Florida, and Mississippi. It is widely naturalized from New England and New York to Ohio and the central and southern plains states.
