An insectivourous perennial herb planted in several wet peat bogs, where it often becomes well naturalised but is sometimes only short-lived. It is found on both raised and blanket bogs, being most vigorous in wet, flushed areas. Some populations in Ireland are spreading by wind-dispersed seed. Lowland.
S. purpurea was cultivated in our area by 1640, and is grown for its dramatic pitcher-shaped leaves. It was initially planted on a raised bog in Co. Laois in the late 19th century but did not survive. However, it spread prolifically after it was planted on Derrycashel Bog (Co. Roscommon) in 1906. It has increased since the 1962 Atlas, especially in Britain, although some Irish populations have been lost to peat extraction.
Native of western N. America.
