This may or may not be Salvia brevilabra! It has been described as having purple/blue flowers, but this specimen, collected in Sichuan has chocolate-red flowers, and is a beauty. Unlike many Chinese species, this Salvia will flower throughout the summer months. It should be very hardy, as long as it does not get waterlogged in winter. It does set seed, but these have yet to be tested as to whether they will come true. It is smaller than some other Chinese species, growing to 2 ft. x 2 ft. There is a very similar plant in the USA, which has yellow markings on the inside lower lip of the flowers. As yet, un-identified.
