Ecology

In Devon, this rhizomatous perennial herb occurs in damp dune-slacks and on adjacent low dunes, and in Somerset in a damp sandy hollow on a coastal golf course. Elsewhere, it occurs as an alien, especially in industrial areas. Substantial ripening of fruit and seed set appear to occur only after a long, hot summer. Lowland.
