Yucca linearifolia 'Dusky Blue'

One of the most beautiful Yucca species, related to Y. rostrata. The 3 ft 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 5F, mid USDA zone 7. Full sun to partial shade and periods summer water with, as always, well-drained soil. LINEAR LEAF YUCCA Agavaceae/Asparagaceae
