About

Lepechinia rossii is a rare species of flowering plant in the mint family known by the common name Ross' pitcher sage.

It is endemic to the Transverse Ranges of California on the north edge of the Greater Los Angeles Area. This species was first described to science only in 2006.

Where it grows

The plant is known from four occurrences, two in the Topatopa Mountains of Ventura County near Fillmore, and two in the Sierra Pelona Mountains east of Castaic Lake in Los Angeles County. The former location spans about 3 kilometres (1.9 mi), and the latter location contains no more than about 1000 individual plants.
