The hong kong orchid tree is named for the location where this hybird was first observed in about 1880. It may or may not be a natural hybrid and the parent species are not definitively known; but the tree is sterile, producing no seedpods. The bauhinia hybrid grows up to 30 feet in height and has a spread of 25 feet; the crown is dense and rounded but somewhat irregular in shape which is improved by trimming. The tree has smooth gray bark; its branches brittle. Leaves are conspicuously of the bauhinia genus, beautiful, butterfly-like, bilobate in shape, 3-4 x 4-5 inches, simple, alternate, glossy, light green and borne on the branch ends. Flowers are large and showy, pink to purple in color, fragrant, funnelform and 5-6 inches wide. Hummingbirds are attracted to the flowers. A seedless hybrid, propagation must be by grafting, cuttings or air-layering. Like all bauhinias, this tree is highly attractive as an ornamental, as a specimen, street or parking lot tree, on the lawn or patio, and in large planters or in a large conservatory. Because it has no litter from seed pods, it is more desirable than other bauhinias.
