Western Catalpa
Western catalpa is a large shade tree with an open, irregular crown. It is grown for its clusters of white, fragrant flowers and enormous heart-shaped leaves.
In June, the long, showy panicles of bell-shaped flowers appear - white speckled with yellow and purple. The flowers develop into thin seedpods. Its bark is reddish-brown or grey and its leaves turn yellow in fall.
Western catalpa works best at lower elevations in the Colorado Springs area. It provides dense shade and has particularly fragrant flowers. The leaves, however, may suffer from hailstorms and wind damage on exposed sites.
