Ground Cover Succulents: Low growing or trailing succulents of various color, form, and texture. Most are easy to grow, spread rapidly, and give great diversity to areas of special interest. Prevent erosion, inhibit weeds, and cover areas where lawn is difficult or expensive to grow. Try a combination of grasses, ground cover, and rocks around a pond for a smashing effect. PLEASE NOTE: Some Sedums are unavailable or shipped semi dormant November to March.
