Calico Spider seems to be overlooked by a lot of gardeners, and that's unfortunate. I have had Calico Spider in my 'zone 3' gardens for several years and, although its foliage is noted as evergreen, it's actually quite hardy. It's listed for 32" and easily reaches full height here, and blooms prolifically.
I have also had polymerous blooms on Calico Spider every year (and, judging by the photos posted, it polys for other gardeners as well). The colours are bright, very strong and sassy in the garden, highly visible. I would recommend Calico Spider without any hesitation.
