I assume you didn't see the leaves Steve?
Not a lot to go on, it just looks like a funny Violet. Whether it is outside the bounds of Violet I'll leave you to judge.
Personally, I doubt it's a F1 hybrid, in my experience they don't really look like either parent. It might be a back-cross with some previous introgression from BLH, they probably look more like one of the parents (I've had a few examples that I think are back-crosses, but proving them is another matter)
