Sedum telephium
Ecology
A perennial herb, found on wood-borders, hedge banks, roadsides, rocky banks and in limestone pavement, often in very small but very persistent colonies. It also occurs as an uncommon ancient woodland plant, but sometimes fails to flower in this habitat. 0-455 m (Falcon Clints, Co. Durham).
Status
Trends
Although native in some habitats, many colonies have become naturalised near houses as this species is grown in gardens, and the native range is now hopelessly obscured by such escapes; all British records are mapped as if they are native.
World Distribution
Eurasian Temperate element; widely naturalised outside its native range.
