A perennial herb with a bulbiliferous rhizome, growing in moist but well-drained, often lightly grazed, base-rich and neutral grassland, in unimproved pastures and hay meadows, and on grassy banks. More rarely, it occurs on shaded river banks and in damp woodland. It is also locally naturalised near houses and in churchyards. Generally lowland, but reaching 580 m N.E. of Helbeck Fell (Westmorland).
S. granulata has been lost from many sites in S. England since the 1962 Atlas, as grasslands have been improved. Naturalised populations include a double-flowered cultivar.
European Temperate element.
