Ecology

A bulbous perennial herb of short turf and maritime heath on exposed cliff-tops and on rocky slopes near the sea, sometimes within the zone regularly affected by sea-water spray. In areas with a pronounced oceanic climate (e.g. Anglesey) it can occur on heathland well inland. Generally lowland, but reaching 415 m in Foula (Shetland).
