Low-growing plants create a carpet of brilliantly colored, 1″–2″ rose-like, double flowers that bloom on sunny days throughout the heat of summer. Very drought tolerant, moss roses need only occasional watering. Wonderful for dry banks and areas with reflected heat such as parking strips or along concrete sidewalks. Self-sows readily!
