Ethnobotany: Extremely rot resistant wood was use for fence posts and rails. Wood was utilized where its soft, straight-grained, and low shrinkage properties were valuable. Occasional wood pieces and furniture parts were fashioned from catalpa. Sometimes grown to attract insects such as catawba worm (larva of the catalpa sphinx moth) which is used for fish bait.
