Bauhinia x blakeana (Hong Kong Orchid) is a tropical tree belonging to the family of legumes, with beautiful flowers similar to orchids or butterflies, which is reflected in the common names with which it is known in English-speaking countries , «Orchid tree» and «Hong Kong orchid tree» ("orchid tree" and "Hong Kong orchid tree").
It is grown as ornamental throughout the world, not only for the beauty of its flowers but also because the fragrance of them is an attractor of hummingbirds.
It reaches 12 meters in height, with a trunk 30 cm in diameter. The leaves are up to 20 cm long and consist of two leaflets with the appearance of a butterfly, divided by a third of the extension between them. Flowers up to 15 cm wide are purple or magenta with veins of lighter shades. The upper petal is darker toward the base. It flowers almost all year round but does not bear fruit because it is a sterile notospecies, a hybrid between Bauhinia purpurea and Bauhinia variegata, which very rarely produces fruit.
