Hong Kong Orchid Tree (Bauhinia blakeana)
Bauhinia blakeana
About this plant
Bauhinia blakeana, commonly known as the Hong Kong Orchid Tree, is a small to medium-sized evergreen tree famous for its large, orchid-like purple flowers. It has distinctive bilobed leaves resembling a camel's hoof, which is why it's sometimes called the 'camel's foot tree.' It is often grown as an ornamental tree in gardens and parks for its beautiful flowers and attractive foliage. The tree is a hybrid and does not produce viable seeds, so it is propagated by cuttings or grafting.
