Cremnosedum 'Little Gem' (Grim and Grim): Dense clumps of bronze green rosettes that turn reddish in full sun. It produces star-shaped yellow blooms in early spring and will develop into a low mat of clustered rosettes. This succulent survives in warm weather but in case of freezing temperatures they can be brought indoors to grow on a sunny window sill or under a grow light. It needs great drainage and infrequent water to prevent rot.
