i'm currently expanding one of my articles in hopes of getting it into the Bushcraft Magazine. through an internet search, i see that some yuccas can be propagated in English gardens (Yucca gloriosa, Y. whipplei, etc.). are there any wild yuccas in the UK? can i pay someone to send my a couple yucca leaves (i would need to know which yucca they come from) so that i can process the fibers? cultivated yuccas are okay as well (but i have more Yucca whipplei and Yucca brevifolia growing around me than i could ever use). thank you!
