Crimson Pirate is a strong bud builder for me. Maybe the size of the clump or the zone matters? I do water mine quite a lot and we have cool mornings. They are also planted in good soil. Maybe the smaller fans do not perform that way until the clumps are larger. My CP was huge! I have never heard of a scape builder. Some dl send up a second or even third round of scapes after the first set has finished, but I always referred to that as rebloom.
