This genus comprises succulent perennials with flat umbels of small star-shaped flowers in summer to autumn. They are native to Asia, Europe and North America. Commonly known as Stonecrop or Sedum (although they are in a separate genus from true Sedums), they are popular garden plants, grown for their clumps of drought-tolerant, fleshy leaves and flat umbels of tiny star-shaped flowers in late summer and autumn. Hylotelephium are best grown in full sun or light shade. They are a good source of late-season nectar for bees. All parts of the plant may cause skin irritation and are toxic if ingested.
