Sedum telephium, often called Hylotelephium telephium, orpine, livelong, frog's-stomach, harping Johnny, life-everlasting, live-forever, midsummer-men, Orphan John, witch's moneybags is a succulent perennial groundcover of the family Crassulaceae native to Eurasia. The flowers are held in dense heads and can be reddish or yellowish-white. A number of cultivars, often with purplish leaves, are grown in gardens as well as hybrids between this species and the related Hylotelephium spectabile (iceplant), especially the popular 'Herbstfreude' ('Autumn Joy'). Occasionally garden plants may escape and naturalise as has happened in parts of North America as wildflowers.
