A noble North American tree, known as the "Indian Bean" owing to the long slender roundish purple pods, 12 in. or more long, which are borne after the trusses of large tubular bell-shaped flowers in July. These are white, speckled and blotched with purple. The leaves are highly ornamental, being ovate, cordate, and 6-10 in. long. The variety aurea has golden-tinted leaves, and is usually grafted on seedling stocks of the type. C. cordifolia (speciosa) is another fine American tree, while C. Bungei comes from China and C. Koempferi from Japan. A good trade is done in plants from l 1/2-7 ft. high, costing from 5s. to 20s. per dozen.
