This coneflower does well in my garden. It is shorter than most of the purple varieties, about 18" tall.

I live in Canada and my coneflowers do very well; I have never had any browning, and they flower till the end of september here in Zone 5.

Blooms well, but a shorter time than the purple Echinaceas. Flower tips brown if too dry or hot. Slower to increase. But still nice!
