This is a rarely seen Salvia from the state of Baja California in Mexico. It is not available in Europe, and would probably not thrive there. It has been commonly named as Salvia China, probably because of the China or sky-blue colour of the flowers. In its natural habitat, it can grow as a woody shrub up to 8 ft. tall, and flowers on and off throughout the year. The leaves are a light lime-green, with white hairs. It would seem to thrive in a hot and dry area. This picture was kindly supplied by Xenomorf, from the Dave's Garden Site. I hope to see this beautiful Salvia one day.
