I think the two would look STUNNING together..go for it..Jeanne

I would not put Crystal Fountain with Josephine since they are very similar in bloom shape except for color. I like more contrast. Kingfisher and Josephine would look great together.

My Crystal Fountain has been very slow getting going as it was a pathetic stem with half a root when I got it from Wayside/Parks. It is four now and looks like a two year old. Can't really judge mature size yet.
