Allium ursinum aka Wild Garlic

Allium ursinum is known as wild garlic, ramsons, or bear’s garlic. It belongs to the amaryllis family, Amaryllidaceae. Its native range runs from western and central Europe to the Caucasus. It is native to Britain and Ireland. This bulbous perennial grows in damp woods and shaded valleys. It can form large colonies on the woodland floor.

Plants reach about 1–1.6 feet [0.3–0.5 metres] in height. Published garden spreads range from 1–3.3 feet [0.3–1 metre]. Colonies can spread much farther as new plants take root. Small, round bulbs grow along branching rhizomes beneath the soil. Each plant has two or three deep green basal leaves. These have an oval shape and smell of garlic when crushed. Their shape recalls the leaves of lily-of-the-valley. Leaves emerge in late winter and die back by midsummer.

White, star-shaped flowers stand above the leaves on bare stems. They form loose, flat umbels about 0.17 feet [0.05 metres] across. Flowering runs from April to June, though some gardens report May to June. The blooms provide early nectar for pollinators. Seeds ripen by midsummer, as the plant enters its dormant phase. Its spring growth also gives small ground-dwelling animals early cover.

Grow it in rich, moist soil that drains well. It suits full sun or partial shade, including dappled woodland light. It accepts chalk, clay, loam, and sand across varied soil pH. Poorly drained clay needs better drainage. RHS rates it H7 for cold tolerance. US sources give USDA zones 5–9, with one listing 4–9. It needs little care and no pruning. Propagate it by seed or division. Rhizomes, bulbils, and seeds let it spread fast. Keep it where expanding colonies will not crowd other plants.

Wild garlic serves both as a spring flower and food plant. People eat its leaves, flowers, and bulbs. Leaves and flowers can be eaten raw or cooked. Leaves add garlic flavour to salads, soups, and sandwiches. Pests rarely cause trouble, but wet soil can rot bulbs. Other possible diseases include rust, leaf spots, and downy mildew. Onion white rot may also occur. Reports describe poisoning in some mammals after very large meals. Dogs appear more prone to harm, so keep them from eating it.
