Hands down, this is the best blue salvia I have grown (and I have tried many varieties.) Mystic Spires blooms profusely, starting long before salvias such as Black & Blue have even begun, and continuing into the late fall. It attracts pollinators but I've never seen it damaged by harmful insects. My only negative? I have great difficulty finding a source for this plant! I'd love to see it available, far and wide, of course grown without harmful pesticides!
