Unlike their more northern cousins, the coming of winter in Central and South Texas is not heralded by plummeting temperatures, icicles and a brown and gray landscape sometimes brightened by the white of falling snow. No, winter there is celebrated with the colorful blooming of the exotic looking Anacacho orchid tree (Bauhinia).
Orchid Tree Info
The Anacacho orchid tree is a member of the pea family and while some authorities claim it hails from the tropical and subtropical areas of India and China, South Texans claim it as their own. It is found growing wild there in two distinct locations: the Anacacho Mountains of Kinney County, Texas and a small area along the Devil’s River where this orchid tree is also known as Texas Plume. Because of the natural adaptations of the orchid tree, culture has spread to other desert areas where xeriscaping is a must.
Growing orchid trees are easily recognized by their twin lobed leaves, which have been described as butterfly-like or Texas style — like the print of a cloven hoof. It is semi-evergreen and will keep its leaves throughout the year when the winter is mild. The flowers are lovely, reminiscent of orchids, with five-petaled white to pink to violet blossoms that arrive in clusters fairly continuously from late winter to early spring, depending on the species. After that, the Anacacho orchid tree will rebloom occasionally after a heavy rain.
