I have only had this one about 3 years so I am hoping as it settles in, it will do better. First year had 1 scape with about 4 blooms. Second year, did not bloom. This year I had 1 scape with about 8 blooms. It appears to be hardy to our winters and has increased some, but so far not a real prolific bloomer and scapes have been rather short. I am hoping this plant will do better after it becomes a nice clump.
