The flowers are conspicuous, pink, and fragrant, with five petals. The fruit is a pod 30 centimetres (12 in) long, containing 12 to 16 seeds. Leaves are alternate. In fall, before the leaves drop, Orchid-Tree is festooned with many showy and delightfully fragrant, five-inch-wide blossoms, the narrow purple, pink, and lavender petals arranged to closely resemble an orchid. These flowers appear on the trees from September through November and are a beautiful sight to see, creating a vivid splash of color in the autumn landscape.
