Years ago, you commented on how this phenomenon is weather related and I have always thought that to be true. Over the years I've had "split" flowers such as this one that will do this once, but never again where you see differing pigment of half of a petal like the lower petal of this seedling. Could you comment on this again as it shows up in a lot of gardens. Isn't this likely to be caused by a weather event during bud formation?
