It's blueish hue is more outspoken in real life, but I would still characterize it as indigo more than deep blue! No matter what, I find it stil lovely and it has a nice fragrance.
I have no exact information about the parentage of this plant. I bought it from Popow - they have earlier on offered more than a few violaceas from the Norton breeding line, so I kind of just presumed by the epithet 'Deep Blue Sea', that this one was just another one of these. But, maybe I'm in the wrong?
