I purchased two of these as healthy-looking mature plants and planted them in a sunny spot in mid-May of this year. I got continuous blooms, but the plant did not thrive the way I had expected... there were fewer blooms, and the foliage ultimately withered and dried up, despite other similar plants in the same spot thriving. But, I never expect to get great performance the first year that I plant a mature perennial. I am happy to report that this plant has already begun to spread, and the new growth looks happy and healthy. The original plant seems to have grown a whole "new" plant to its side - I have new, mature leaves, and blooms just opening now, in early October, on the edge of zones 4b and 5a. I also see smaller seedlings coming up around the plant. I fully expect that next spring this plant will come up healthy and thick. It has attractive foliage, beautiful flowers, and the dead flowers will add interest in the winter.

Nice color, another prolific bloomer. Really short and a nice contrast to the taller echinaceas.

First year growing, but spreading quickly. Multiple flowers. Very pretty plant. A little taller than anticipated.
