Karen that is Beautiful.. Have you found any other blooms on it...

That's the first but I expect more will be opening soon. I found a bloom on another of the plants I grew from the amethystina cross. I made another post.

Karyn,

I think that these hybrids are actually pure amethystina.
I know of two people that have Passiflora amethystina 'Minas Gerais' (which I think is what yours looks like) and they have both told me that theirs is self-fertile, and one of them grows no other passion vines.

The differences in these new hybrids can probably be explained though genetic variation, since these are a result of different combinations of traits from its grandparents, so you can expect some differences.

I agree with Abdiel. I used to have amethystina 'minas gerais' and the flowers looked just like that.

I don't think they are pure P amethystina because some of the seeds from the same fruit produced very different looking blooms. Some were the same color with straight filaments (whatever they are called) other flowers were blue, some with curly filaments and others straight but all were quite long.

Well, then I guess it's still a mystery!
