Catalpa ovata – Yellow Catalpa – Chinese Catalpa – Indian Bean Tree –

Description

Catalpa – Indian Bean Tree – There are about 11 species of fast growing, deciduous small to medium trees, in this genus. They occur in Eastern Asia, North America, and Cuba on riverbanks and in woodland. Their large ovate leaves are opposite or in whorls of 3. Catalpa are grown for their showy foliage, for their large, bell shaped, 2 lipped flowers, held in upright, terminal panicles or racemes in mid and late summer, and for their pendent, bean like, up to 30″ long, narrowly cylindrical seed pods, which develop in autumn. Their wide spreading habit and conspicuous flower panicles are seen to best advantage when they are grown as specimen trees. Those with colored foliage are also effective in a large shrub border, if pollarded or coppiced annually or biennially, they produce large ornamental leaves. Some species yield valuable timber. Grow in fertile, moist but well drained soil in full sun, sheltered from strong winds. Prone to powdery mildew, white rot, dieback, leaf spots, anthracnose, mealy bugs, whiteflies, scale insects, and aphids. C. ovata – Yellow Catalpa – Chinese Catalpa – This small tree from wooded area of Western China grows 30′ feet tall and wide. It produces a spreading crown composed of pale green, broadly oval, 10″ long leaves that are often 3 lobed and downy beneath. Yellow catalpa is not as spectacular as other species, having relatively small flowers of dull white with yellow and red markings in upright panicles to 10″ tall.   The seed capsules grows to 12″ long.
