Salvia regla in full sun - or tall Salvia that likes full sun?
I'm looking for a tall drought-tolerant Salvia for a sunny spot in clay soil. We have a mature Salvia regla (see photos below) that grows on the north side of the house where it gets only morning sun in summer. I'd love a Salvia of the same size with orange, red, or yellow blooms that tolerates sun.
I'd like one that looks similar to this -- in other words, not a dense bush but one with an open graceful habit.
I'm considering S. maderens. Any other suggestions that meet this criteria?
