Happenstance,
Smaller and more refined!? I inherited this monster when we moved into our current house and it was already over 10 feet tall with a nearly 2 inch thick main stem! It seems like if you were patient enough you could grow it into a standard. I hacked it down to a reasonable size this fall; but, it is still a pretty good size bush. I do really like the flowers and the leaves are quite handsome with a pleasant aromatic scent.
I haven't tried Salvia clevlandii. I did get a small Salvia brandegii (brandegei?) this fall, which I guess is somewhat similar. I've put it in the sunniest part of my garden and am hoping it will be established by next year.
