The orchid tree (Bauhinia purpurea) belongs to Fabaceae (the Pea family). It is a small deciduous tree that is native from southern China to Southeast Asia. It is now widely planted in tropical and subtropical areas. This tree grows fast, grows to about 6-10 m in height, and forms a large canopy. The leaves are largely tied in two and alternate in the shape of a sheep's hoof. In addition, they are entire, have no hairs on the surface, and petioles. The pale pink to purple orchid-like flowers come in bloom from October to December. |
