Ecology

A long-lived rhizomatous perennial herb of well-drained sloping sites in deciduous woods, particularly those of Fagus, on calcareous soils. It is a poor competitor and does not form large colonies. Flowers are rarely produced and seed-set is very low, possibly due to the rarity of suitable pollinators. Lowland.
