So much confusion in the identification of many Salvias. Nurseries that have something like this as one out of thousands of plant varieties they grow cannot be expected to know what the "real" variety is supposed to look like. So many retailers buy their stock from wholesalers who are faced with the same issue - is this or is this not what I was told it to be. I see mislabeled Salvias all the time. Now, having said that . . .
Lapis Lazuli is bicolor, medium lavender blue and a whitish blue. Not pure blues, mind you - they have pink in them. But most people would say these flowers are blue. Such shades can vary a great deal with time of year and weather, and have not been easy for me to capture photographically. This picture is OK, but not perfect:
Cooler weather seems to bring out the blue.
My 2 cents worth.
