Ypsilandra cavaleriei



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.
I got it from Chen Yi in China.

Plants of the World online says:

"This name is a synonym of Helonias thibetica."

In the Hardy plant Society Shade Group newsletter for March 2019 it says:

"This is a nice little plant, very similar to the more common Y. thibetica. In my experience it is smaller and the flowers have a stronger pinkish cast, but Flora of China says that the reliable difference is that the 'petals' are slightly longer in Y. thibetica."

Cotswold Garden Flowers says:

"Scented spidery pale magenta-pink flowers with blue anthers and pink filaments over a long period Jan-Jun (age greener), fresh apple green foliage goes bronze in winter, 25cm. Moist shade in poor well-drained soil."
