A shade-loving rhizomatous perennial herb usually found in woods with little ground cover, especially those of Fagus, but also extending into chalk scrub. It is restricted to well-drained soils on chalk and oolitic limestone. It is usually self-pollinated and the flowers often fail to open entirely. Lowland.
Clearance of woodland, particularly since 1930, has resulted in the loss of many sites for C. damasonium. It is still plentiful, however, in suitable habitats, and its ability to colonise young Fagus plantations means that new populations are occasionally found.
European Temperate element.
