Flowering now is the Federally Endangered hardy cactus, Escobaria minnima. Our plants are now almost five years old from seed. We are thrilled to see that these have performed so well, sailing through our 11 degree F. winter this year. This extremely rare gem (G1 rank) is only found a single rock outcrop in Brewster County, Texas, hence it was added to the Endangered Species list in 1979. (Hardiness Zone 5b-9b).
