10-12" tall x 10-12" wide. (Seed propagated.) Re-planting this Ozark Mts. native succulent in my rock garden after a long absence, I realized what a great little plant I'd been missing. Originally brought into cultivation by New Mexico landscaper, nurserywoman and author Judith Phillips, this selection of the species is remarkable for its vigor and its fabulously showy display of quarter-sized rose-violet flowers. It thrives in full sun growing on poor sandy/rocky soils. Blooming starts in early summer and continues through early fall. The flowers open in the afternoon, so it's always a treat to come home in later afternoon to clouds of its intensely colored flowers dancing in the breeze. Zones 5-9.
