Salvia regla (Mountain sage) is a deciduous perennial that is native to a small area of the Chisos Mountains in west Texas and a large area of Mexico, in the states of Coahuila, Durango, and Oaxaca.

The specific epithet is probably from the town of Regla in the state of Hidalgo.

It has been widely planted along the Texas flyway for migrating birds, and is an important food source for hummingbirds returning to the tropics in September and October.

It grows on upright stems which give it a stately appearance.

The mistletoe-green deltoid leaves are deeply veined and about 1 inch wide and long.
