Big red sage is a beautiful perennial in the mint family. Sometimes growing to a height of five feet, its burgundy-red tubular flowers are a favorite with the hummingbirds. It is found in Central Texas growing along stream banks amongst the limestone outcroppings. Herbicides, erosion, and the lowering of the water table in the Texas Hill Country are its main threats. The San Antonio Botanical Garden maintains a collection in their greenhouses and on the grounds (Merritt, 2001. pers. comm.).

Conservation, Ecology & Research
Lowering of water table
Poole and Janssen (1996) reported on a four-year survey of demographic trends for one location of this species on a highway rights-of-way.
Schaal et al. (1992) found that this species has low levels of genetic variation, a pattern that appears to be consistent with a species that has always had a fairly low level of genetic diversity.
