A North American native tree of great beauty, the Southern Catalpa, sometimes called "catawba tree," is adored by gardeners for both its foliage and showy flowers, and by fishermen for the caterpillars of the catalpa sphinx moth that visit the tree and are collected for use as great fishing bait. Fresh or frozen, due to their tough skin, one "catawba worm" can catch several fish. Birds, including turkeys, will feast on the worms. In late spring to early summer, abundant clusters of exotic-looking, fragrant, bell-shaped white flowers with purple and yellow markings in their throats adorn the tree. Very broad, heart-shaped bright green leaves up to 10 inches long and 6 to 8 inches wide provide a lush, tropical look and feel in the landscape. An exceptionally adaptable tree anyone can grow, the Catalpa thrives in acid or alkaline soil that is moist or dry, takes the cold down to -20F and the heat down to Zone 9b in central Florida, and has no serious pest or disease problems.
