About
Salvia brandegeei is a perennial evergreen shrub in the mint family known by the common names Santa Rosa Island sage or Brandegee's sage. It is a fragrant plant characterized by lavender flowers and dark green leaves. For many years, it was thought to be native only to Santa Rosa Island, one of the Channel Islands of California, until it was discovered along the coast of Baja California. It is threatened by development and mining along the mainland portions of its range, but otherwise has a stable population on Santa Rosa Island.
How to grow it
In cultivation, the plant will reach 4–5 feet tall and up to 7 feet (2.1 m) wide. It likes full sun, dry conditions, and will grow on sandy or clay soil. It can tolerate temperatures down to 0 °F for several hours.
Where it grows
This species can be found on Santa Rosa Island, California and on a strip of coast in Baja California. This plant is widespread on Santa Rosa Island, even becoming co-dominant in numerous large, healthy populations. It is found in the shrubland on the island. In Baja California, the plant is found on the immediate coast from the vicinity of Ensenada south to San Quintin, in a 40-mile long strip. It is found in Baja California in habitats of maritime succulent scrub and chaparral.
