The Yellow Catalpa is a small deciduous tree that has large, heart-shaped leaves and clusters of showy light yellow flowers. It grows to 30 feet tall with a spreading crown and light green, cordate leaves up to 10 inches long and wide. In late spring, it produces bell-shaped, orchid-like yellowish-white flowers up to 3/4 inches long, with purple and orange inner spotting. After flowering, it produces long, slender, green seedpods up to 16 inches long. It is an Asian relative of the more commonly known northern catalpa, which has beautiful white, striped flowers. This is a good tree to grow for the gardener that wants something that is more unusual and less common than the regular catalpa. It can be grown as a shade tree and as a flowering tree. Native to China. Flowers in May and June. Hardy in zones 4-8.
