Catalpa, botanically known as Catalpa species (commonly Catalpa bignonioides or Catalpa speciosa), is a fast-growing deciduous tree valued for its large leaves and ornamental flowers. It develops a broad, spreading canopy with heart-shaped foliage and produces clusters of showy white flowers followed by long, slender seed pods during the growing season. This tree adapts well to a variety of climates and performs best in full sun with well-drained soil. Catalpa is commonly used in landscape planting, shade gardens, and avenue planting, where it establishes readily from seeds and grows vigorously.
