Four or five years ago, I picked up two Wakaebisu whips from Telperion Farms, which was described as a "hose in hose", multicolored Satsuki. The first one, for 2 or 3 years only had single, typical shell pink, to ,my eye a pink with a touch of orange, the color you most often see on Wakaebisu. It wasn't until 2014 that it finally started making the multi-colored flowers. In 2015 I got some hose in hose flowers, but most have been singles. I haven't taken pictures as I have been pruning it hard to try and impose a style on it. So I have no recent pictures. These 2 photos are of the first one from 2014. I like Wakaebisu, it is a nice strong growing cultivar that seems to forgive mistakes reasonably well.

The second one has only bloomed white, so far. It has not opened up yet for 2016, we have had a cool spring so far. If it continues to bloom white, I will have to assume I got a mis-labelled plant, or the all white sport of Wakaebisu, which has a different name. But the variation in flowers from year to year is really cool, and is also why I don't rush to re-label the name of this second one. The growth habit and leaves are identical to the normal colored form, so it might very well be the same variety.
