Hardiness:
Not known?
I haven't had any experience with this species yet, but I have grown
some of the species that it grows with in habitat: Sclerocactus pubispinus,
Sclerocactus spinosior, Pediocactus simpsonii and Escobaria
vivipara, those species can be grown in an unheated greenhouse here
in Denmark, and I would think that Yucca harrimaniae ssp. gilbertiana
would be OK here too.
