Echinocereus engelmannii x Echinocereus reichenbachii
Echinocereus engelmannii x Echinocereus reichenbachii was a mistake in the greenhouse and now we have these fast growing plants that should be very hardy. The echinocereus engelmannii was from The great Salt Lake desert and the echinocereus reichenbachii was from Pueblo, CO. Both places get -20F in winter and so the hybrid which looks intermediate to more like reicebachii should be very cold hardy. So far these are the fastest growing seedlings in the greenhouse. So im thinking this hybrid may have great winter wet tolerance but IDK. Good plant to trial in your garden.
