Eryngium leavenworthii :
Also called Leavenworth’s Eryngo, Eryngo, False Purple Thistle
This one is my icon on Naturalist. I love them, like little purple pineapples. They are very prickly but very drought tolerant. There used to be tons of them where the new St. David’s Emergency Room is in Leander. They wiped out a big field of them when they built.
