Squirrel Corn

Summary

Squirrel corn is a native North American, clump-forming, tuberous perennial that grows about 15–30 cm tall with finely divided grey-green leaves. In spring, arching stems bear fragrant white heart-shaped flowers that hang above the foliage, sometimes with pale pink tints and two spurs, and the plant goes dormant in summer. It prefers partial to full shade and moist, humus-rich soil of neutral to slightly acidic pH, tolerating loam and clay; hardy in USDA zones 3–7. Propagation is by seed when ripe or by division in spring or after leaves die back, with seeds dispersed by ants; in gardens it suits woodland or shade borders, cottage plantings, and underplanting of roses and shrubs. The plant is generally pest- and disease-free, though slugs and snails can affect emerging foliage, and all parts are poisonous if ingested in large quantities.
