I grow this one and really like it. It flowers profusely in my garden, and though it is difficult to tell from the close-up photos posted by nurseries, the flowers are relatively small, about 2” in diameter. They make up for that in number and in length of bloom which is extended by the fact that after the petals drop, the central pompom holds on for another week or more. So there is often combo of full flowers with the pink pompoms. It is more popular with pollinators than many of my other clematis.
