A belated
, longk!
I agree, I hope that 'Nachtvlinder' makes it here, too!
Does it set seed and, if so, do the seedlings resemble the mother plant at all?
I see that it is being sold as Salvia x jamensis but it looks like there is another dark blue/purple species involved, too.
I've had a couple ex 'Mesa Purple' seedlings with similar coloration but they weren't that saturated and dark.
