Had eight White Swans and really liked them a lot. But all seem to have died in the first winter. In last five years, also planted Pixie Meadowbrite, Milkshake, Meringue, Raspberry Truffle, Harvest Moon, Magnus, Kims Knee High, Merlot, and a couple of others. Milkshake, Meringue, and Raspberry Truffle are all first year and I will see what happens in Spring. All the others died off. Think they don't like my soil. Or could be the extreme summer was too much. Going to try a passel of them next year in some raised beds I'm putting in. I love Echinacea of all kinds and hate to think I can't keep them going.
