The orchid tree is the most common Bauhinia cultivated in the sub-tropics and tropics. A 20 to 25 foot (6-7.5 m) subject, it is inclined to bushiness or multiple trunks. It also is extremely variable in its blooming period, foliage quality, and leaf-holding characteristics according to soil, exposure, and weather vagaries. It may drop its twin-lobed leaves in midwinter or remain evergreen in moist hot areas. The principal show of orchid-lavender to purple, white, or even pink, broad-petaled flowers is in late winter or early spring, with or without new foliage.
Following mild, dry winters, the display is sensational, and blossoms may
continue to form intermittently on different sections of the tree, occasionally
even into autumn. The plant likes heat but withstands considerable cold. It does
best in well-drained sunny locations. Fine specimens occur in many parts of the
world—Hong Kong, Costa Rica, Cuba, South Africa, southern California where it
occurs from coastal areas inland to Palm Springs, and central and southern
Florida.
