Ken, that Ismene looks white. As I recall, Sulphur Queen flowers are a pale primrose yellow. Is your plant able to produce seed? I was surprised that rain could have such an effect -- I leave my Ismene (xfestalis) outside all the time, here in the S.F. Bay area. They seem to respond to the season, and not to the amount of water. So now, despite the wet weather, they are evidently inclining toward dormancy. David E.
