I think there is a tendency to use alba and flava interchangeably. Obviously that's not correct since alba denotes white, and flava yellow. I have a feeling that mine is from flava parents. Yours seems to have a bit more color on the pouch than mine.
It takes about a week or so for the petals on mine to fully twist. I do love the twirlies!

Here's an update. I took these pics when it was in full bloom. The plant is now on its last bloom on each spike. There were three blooms on each and usually two flowers were open at a time.
