Award-winning Catalpa bignonioides (Southern Catalpa) is a large deciduous tree adorned with an irregular, broad-rounded crown and short, crooked branches clothed with huge, heart-shaped, light green leaves, 10 in. long (25 cm). They are glossy on top and densely hairy on their undersides. They give off an odd aroma when bruised. In late spring to early summer, ravishing conical panicles of 10-20 trumpet-shaped, white flowers, 1.5 in. across (4 cm), with abundant yellow stripes and purple speckles on their throats, bloom dramatically above the leaves. The flowers give way to prodigious quantities of long slender green seedpods, 15 in. long (37 cm), that mature in fall to dark brown and persist through winter. The foliage seldom displays a hint of fall color. The pale gray to reddish-brown bark is fissured and prominently ridged on mature trunks. Southern catalpa is very adaptable to adverse conditions and serves as an ornamental shade or street tree.
