Bauhinia blakeana commonly called the Hong Kong Orchid Tree is a legume tree of the genus Bauhinia, with large thick leaves and striking purplish red flowers. The fragrant, orchid-like flowers are usually 10 to 15 centimetres (3.9 to 5.9 in) across, and bloom from early November to the end of March. Although now cultivated in many areas, it originated in Hong Kong in 1880 and apparently all of the cultivated trees derive from one cultivated at the Hong Kong Botanic Gardens and widely planted in Hong Kong starting in 1914. It is referred to as bauhinia in non-scientific literature though this is the name of the genus. It is sometimes called the Hong Kong orchid (香港蘭). Commonly called by the people of Hong Kong by its Chinese name "洋紫荊".
