Echinocereus klapperi x E. reichenbachii

Echinocereus klapperi x E. reichenbachii has survived -11F in our garden. However, a friend in Wiggins, CO had these survive ice storms, heavy snow and take -26F with no damage. Echinocereus klapperi is a small mexican claret cup species that blooms mid-summer with long flower tubes. I was able to catch a late out of sync E. reichenbachii blooming and crossed these plants. Even tho the seed came off of E. klapperi the plants look more like Echinocereus reichenbachii. Again try at your own risk.
