Echinocereus triglochidiatus - Questa, NM 7,500ft

Echinocereus triglochidiatus - Questa, NM 7,500ft is from a very unique area. Just uphill from Questa, NM is a large Pinon area that is heavily nut harvested in the fall.  This area gets colder than -20F. The area also receives heavy winter snows. Plants from here I would think to be zone 4 if you have drier winters. Very worth trying if you live north of Colorado. Try at your own risk.
