Answer: Most people think of orchids as tropical perennial plants suitable for growing indoors, or outdoors in tropical climates. There is a plant called Chihuahuan orchid shrub (Bauhinia lunarioides) which develops woody stems as it ages. It is evergreen growing 6-8ft wide with a spread of 5-6ft. The 2-lobed leaf looks like butterfly wings and is grayish green. Bauhinia is a profuse bloomer. Pink or white orchid-shaped flowers appear in spring and summer.
