Nursery contributed plant descriptions

One of the most beautiful yucca species, related to Y. rostrata. The 3' rosettes atop an eventual 3-8' trunk resemble the Australian grass trees, Xanthorrhoea, or a dim version of Dasylirion quadrangularis. Flattened somewhat triangular leaves of spring green to nearly turquoise and white flowers to 3' or so above the rosette. From only a few scattered localities, these from north of Galleana, NL, Mexico, in a most diverse habitat. This form is particularly blue and quite vigorous adding 6-8" of trunk each year. Our plant often elicits comments from garden visitors. The southern habitat of the species would indicate lack of frost tolerance but plants have so far withstood 5 °F, mid USDA zone 7. Full sun to partial shade and summer water with, as always, well-drained soil.
