Native to the Balkans, this sturdy perennial forms dense mats of attractive silver-grey foliage, 4 - 6 inches tall and 18 inches wide. Prolific bloomer, with clusters of small white flowers in the late spring. This handsome perennial makes a fine addition to a rock garden or perennial border, where it thrives in full sun and is drought tolerant once established. Trim back spent flowers to keep tidy. Pollinator favorite. Fire and deer resistant.
