I have April Moon on its own roots here. It's been here two years and hasn't impressed me much so far. It has had a few blooms that are delightfully shaped and very attractive, but it's not a strong-grower for me. Maybe this year it will hit its stride?? If not, I think I'd better move it, or try something else. It is in a spot that's partially shaded, so that could be a factor.
Hawkeye Belle is on my *someday* list.
