I found a website that sells some yuccas I'm not familiar with. Does anybody know or have experience with the following yuccas:

1) yucca arizonica
2) yucca grandiflora
3) yucca periculosa
4) yucca angustissima

Can I grow these in an East Coast northern zone 7a? I am able to grow aloifolia, treculeana, torreyi, rostrata, thompson, and elata without a problem.
