Discussion | Specimens of waifs of Sedum rupestre are known from as early as 1876 in Massachusetts. It was first reported as cultivated in the United States in 1914. Most naturalized records of S. rupestre in North America have been incorrectly named S. reflexum. Sedum rupestre is ephemeral on Prince Edward Island, probably not truly established, and is a garden escape in Ontario.
