About
A drought-tolerant houseleek, forming tightly packed, symmetrical rosettes of fleshy, pointed leaves. Star-shaped, pink or red flowers appear on stout stems in summer from mature rosettes, which die after flowering but are replaced by surrounding offsets. 'Cornstone' is a striking addition to any collection.
