Funny you should ask. I just bought one this past weekend for a kusamono composition I am putting together. It is a white variety with subtle hints of pink.
You can't see the pink highlights in this photo but mine has it. It's very subtle and is most noticeable before the flower buds open. It's a nice contrast between the pinkish flower buds and almost pure white flowers.
They are semi woody plants and I wonder if they could be made into mame sized bonsai.......
