ISI 2006-33. Yucca glauca Nuttall var. glauca

Dwarf yuccas make desirable container or rock garden plants and this one is hardy to 0°F. Though the taxon is variable in habitat, this population forms rosettes to only 20 cm diameter; the leaves are slender, glaucous, and linear, with a few marginal filaments. Rhizome divisions of HBG 94020, about 40 clones from seed collected by Zsolt Debreczy & Kathy Musial, Oct. 27, 1999, at a rest-stop along Interstate 80, just W of the Nebraska border, near Pine Bluffs, Wyoming. $8.

Bob Nold of Lakewood, CO, where this species grows wild, reports that my statement of its hardiness was overly conservative. Rather than being hardy to a mere 0°F, a more accurate limit would be -40°F!
