Ecology

A rhizomatous perennial herb of neutral or acidic soils in old woods and shaded hedge banks, more rarely found amongst scrub and around rock outcrops. In woods it is a light-demanding plant which may re-appear from buried seed after coppicing. It is also cultivated as a garden plant, where it is persistent and can be very invasive. Generally lowland, reaching 455 m at Rhydymain (Merioneth).
