@vonny,
many different varieties:
Field of Salvias at San Marcos Nursery (my old favorite nursery, have met the guy in the photo (owner) several times, way back when, when he used to give some lectures & tours to landscape designers. Probably he still does that, but I don't live near there anymore. Beautiful drive to get there from Los Angeles, wonderful plants.
look at the link for lots of kinds of Salvia varieties - or click around, I remember they have many (I love salvia...)
