FBTS said:We've seen this plant get very large in ideal conditions. In short seasons expect 5 feet or so. But where it can overwinter and start early the following season, they get large. Salvia mexicana is a spectacular species all-in-all, if you can grow it. This variety is one of the earliest to bloom, BTW.
FBTS said:On our site we note this blooms in the fall and winter. Essentially they start late in the summer (if established) and go until the weather gets horrid. In mild winter years that could be February. But spring - no.
