These aren't flowering right now. It's just a bit cold out there - for another night. But they are out there shivering in the cold night. These particular Echinocereus viridiflorus plants come from Colorado, up near the border with Wyoming, and they're quite hardy. They'd better be. Our temperatures right now are almost rivaling those of Wyoming and Nebraska. ... Notice I said "almost"! But it's going to be into the teens again tonight!
