AlsoHong Kong orchid tree, Blake's bauhinia, Hong Kong bauhinia, Butterfly tree

A semi-deciduous tree 6 to 10 m tall with an open, irregular crown and light green two-lobed leaves that resemble butterfly wings. Its large, fragrant, rose-purple orchid-like flowers, about 15 cm across, open from November to April when little else is in bloom. The hybrid is sterile and sets no pods; every tree in cultivation is descended by grafting or cuttings from a single tree in the Hong Kong Botanic Gardens.
