Salvia texana

Salvia texana (Texas sage) is a herbaceous perennial native to the U.S. states of Texas and New Mexico, and in northern Mexico, typically found growing in limestone soils. It grows 1 to 1.5 ft (0.30 to 0.46 m) tall, with hairy lanceolate-oblanceolate leaves. The flowers are purple-blue. It resembles Salvia engelmannii, but has a longer bloom period, smaller and darker flowers, and unopened green buds at the top of the plant.
