Marilyn, so far as I know, this is the species. There was no cultivar name attached to the tag when I bought it a number of years ago. The color here in our garden is this dark blue, just love it. I call it navy blue or royal blue to give you an idea. I know it is not "Black and Blue" and I have looked at FBTS's S. guaraniticas hybrids and if it is a hybrid, I think "Blue Ensign" might be the closest to what we have. Okay, I just entered this is the Plant Database and I see it is also called Salvia coerulea--I did not know this at all, learn something everyday.
