Echinocereus engelmannii - House Rock Valley, AZ
Echinocereus engelmannii from house Rock valley is a cold hardy form for us in Pueblo. We have had them survive several severe winters taking -22F and -17F. We have good drainage and dry winters. Should be a good population for people to try in their gardens. Plants can be black or golden in color, in reference to spines. One thing I will say is that E. engelmannii can be a finicky species.
