This grows wild in the alpine/mountain areas around Monroe, UT, where it is absolutely stunning - long stalks of deep purple with the bright yellow anthers. Easily Zone 4 possibly 3. (snow on the ground until mid-May, first snows in September). I was able to start one successfully from several seeds last year in the valley (zone 5b), hopefully it has survived our unusually dry and warm Winter.
