I have had Darius for several years, 10 or more. I don't think it is the prettiest flower of this look in my garden, but it grows better than average. I've given lots of it away and still have 3 large clumps of it. It never fails to bloom & blooms for a long time. I've never done a bud count & I do have very large clumps, but as long as it blooms, it must be pretty good.
