Musk Rainbow is reported to be an extremely sensitive variety. We brought it into our collection in 2014 and are still figuring out the quirks, but it bloomed for us in 2014, branched out nicely, overwintered without any issues, and so far has been behaving. The color is unlike anything that we have grown before and the scent is strong. When the flower opens it’s a orange/pink/gold blend that eventually fades to a greyish purple.
