Allium victorialis aka Alpine Leek

Allium victorialis is a bulbous perennial in the Amaryllidaceae family. Common names include alpine leek and long-rooted garlic. Its native range runs from Europe to the Himalayas. It grows in temperate climates and is not native to Britain. Wild habitats include rocky mountain sites, woods, pastures, and stream banks. Some populations grow on moist slopes or lime-rich ground.

The plant forms clumps and reaches about 2 feet [0.6 metres]. Its broad leaves are glossy and dark green. They look much like leek leaves and die back seasonally. Small bulbs grow in clusters along a short rhizome. Tall stems bear round heads of cream-green flowers. The flowering season extends from May to August. Plants reach their mature size in one to two years. The broad leaves and raised flower heads give beds contrasting shapes.

Choose a sheltered site with full sun for garden plants. RHS guidance warns that they grow poorly in shade. Plant the bulbs fairly deep in soil that drains well. Mix in plenty of organic matter and use peat-free soil. Loam and sandy soil both suit this plant. It tolerates acid, neutral, and alkaline conditions. The listed moisture range runs from dry to moist. RHS rates its cold hardiness as H6. Plants For A Future lists USDA zones 6–9. Divide the bulbs in winter to make more plants.

This species suits borders, bed edges, courtyards, and cottage gardens. It can also grow in pots on a patio. Remove dead leaves and old flower heads as they fade. Watch for stem and bulb eelworm, leek moth, and onion fly. Rust, onion white rot, and downy mildew can also occur. Plants For A Future does not flag it as weedy. These risks still merit checks when leaves or bulbs show damage.

The leaves and young shoots have a mild garlic taste. Bulbs, leaves, stems, and flowers have recorded food uses. They may be eaten raw or cooked. The small bulbs can stand in for onions. Reports differ on flavour strength, from mild to quite pungent. Young plants also have a recorded use in pakora. Plants For A Future records traditional medicinal uses for the root. These records do not establish that treatments work. It also reports using plant juice to deter moths. Claims that whole plants repel insects and moles remain reported uses.
