Salvia regla
Salvia regla 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 is also referred to as the "queen of the Chisos Mountains". 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.
