Grown from seed we collected from plants growing on a sheer rock face in Colorado. This population is known for its color variations from the usual whitish theme and our young plants have yet to flower so we are twitchy with anticipation. We first saw this species growing among the ancient Bristlecone Pines in the White Mts - that day was magic! Grows in rock cracks/crevices or stony open ground in dry situations. Evergreen mat-former.
