Agastache is a wholly North American genus. Sanders (1987) has provided a treatment for the 4 Texas species, 3 of these belonging to the section Brittoniastrum and one to the section Agastache (A. scrophulariifolia ), the latter possibly introduced. In Texas, the species are mostly confined to montane regions of the trans-Pecos where they are relatively uncommon.
We are not aware of ethnobotanical uses of the species native to Texas, but closely related Mexican species (e.g., A. mexicana ) are reportedly grown in household gardens and used to treat gastrointestinal, nervous, and cardiovascular ailments, among other uses (cf. Bye et al., Phytologia 62:157-162. 1987).
