Bauhinia blakeana (Hong Kong Orchid Tree) - Partly deciduous for a short period. This tree grows into an umbrella shape and reaches 12-20 ft. tall and 15-20 ft. wide. It blooms from late fall to spring, with flowers shaped like some orchids. Colors range from cranberry maroon through purple and rose to orchid pink, often in the same blossom. Gray-green leaves tend to drop off around bloom time, but the tree does not lose all of its foliage.
