A low, mat-forming perennial groundcover with shamrock-like leaves and small pink or white flowers. Sometimes grown for its tart leaves, eaten fresh as a garnish or in salads.

Why grow it

It forms a dense carpet in shade under conifers and in woodland gardens, where many sun-loving groundcovers and lawn grasses fail. Once established it needs little upkeep compared with many other shade groundcovers.

Watch out for

Leaves scorch in full sun and wilt in prolonged drought, so it needs shade and fairly steady moisture. It spreads steadily by rhizomes and can crowd out smaller neighbors.
