Chris is right - this one responds a lot to depth. And I've found that if it is left for several years undisturbed, it will actually "adjust" its depth... lots of hostas do this, but it is really obvious in CC... the plant will dither a little, maybe look a little ragedy, then one year it will have the crown at just the right depth and it will form an incredibly dense tight mound. I think the ones that are deeper often give the bigger leaves on CC as it is struggling to adjust itself...
