Hi, I have a violet I started from a leaf cutting which has been trying to bloom for a couple months now. I feel like the flowers never stretch out and only half open. The leaves are also convex (like inverted spoons). I have it away from the other plants, for fear it is diseased. Would someone please advise me as to what to do? It would be nice if I could save it, as the half flowers look like they'd be gorgeous if they'd just open fully. Actually, now that I've gone to take a photo, I see the leaves aren't as deformed as they have been in the past, but still, the buds fail. Thanks!
