Supposed to be a white flowered species, I think there is some confusion about the proper naming of the plants currently available commercially. If
it flowers next spring, I will be in a better position to comment.

I am not sure about the difference between Y.cavaleriei and Y.thibetica, both names claim
to be in cultivation and there are certainly several distinct clones about. If I had to choose, based on
the information in the Flora of China, then I would say this was Y.cavaleriei with stamens just
exceeding the tepals, but I wouldn't say it with firm conviction.
