Thistle native to the U.S. Pacific coast, with white-hairy bristle-studded leaves and ghostly flower buds that open to expose magenta-red flowers. I tried to grow this once in Pennsylvania, and once in Texas; unfortunately, I never saw flowers. Mostly likely, the winter was too cold in Pennsylvania, while they definitely expired in the Texas summer heat. So there's just leafy photos here.
