Texas kidneywood is a warm season perennial shrub found in South Texas. It grows in Texas and south into Mexico. In Texas, it can be found in the Trans-Pecos, Edwards Plateau, Southern Coastal Prairie, and Rio Grande Plains regions. In most cases, it prefers calcareous soils and is found as part of brushy, chaparral vegetation. Texas kidneywood prefers full sun or light shade. It is drought tolerant, but may temporarily defoliate under extended drought conditions. It grows rapidly under moist conditions. The leaves are browsed by livestock and white-tailed deer. Texas kidneywood can be grown from seed or from cuttings. Texas kidneywood germinates best when temperatures fall between 68–86º F and when there is about 12 hours of daylight. Colder temperatures have been known to reduce germination, whereas higher temperatures tend to reduce the survival of new seedlings. However, Texas kidneywood has been known to germinate with no light and temperatures from 59–104º F. Young plants may do better in light shade until they become better established. Texas kidneywood can also be grown from soft or semi-hardwood cuttings. Cuttings 4 to 6" long should be taken in the summer and early fall. A rooting hormone should be used to facilitate root growth. Cuttings tend to root in 3 to 4 weeks. Seedpods should be harvested when they have turned brown and dry. Seeds are kidney-shaped, slightly-plump, and light to darker brown when matured. Seeds or pods should be dried at room temperature for several days before storing. It is recommended that seeds or pods be fumigated and stored at cold temperatures.
