Growth Stages

Stage	BBCH	Notes
Planting bulbs or sowing seed	0	Plant bulbs about 3in deep, spaced under 12in apart, in shaded, moist, humus-rich soil; seed can also be sown but may take up to 2 years to germinate (NC State Extension).
Spring leaf emergence	1	Broad, tulip-shaped basal leaves emerge very early in spring, among the first edible plants to appear in the woodland, on a distinctive red-pigmented stem (NC State Extension, USFWS).
Leaf dieback and flowering	6	Foliage dies back before a leafless flowering stem appears, bearing small white flowers later in the season (NC State Extension).
Dormancy and clump spread	9	Plant is dormant through summer, autumn and winter; clumps spread slowly by bulblet formation year on year (NC State Extension).

At a Glance

Harvest & Storage

When to pick: Harvest in early spring, as soon as the broad basal leaves emerge -- one of the earliest edible plants to appear in the woodland (NC State Extension). Harvest sustainably: take only a portion of each clump's leaves/bulbs and allow most plants to regrow, since wild leek populations are slow-growing and can take years to recover from over-harvesting.

Diseases

Bulb rot (wild leek, overly wet soil)

NC State Extension: bulb rot occurs in overly wet soils -- good drainage despite consistent moisture is essential.

Pests

Bulb mites (wild leek)

Rhizoglyphus spp.

NC State Extension: bulb mites are a known pest of wild leek bulbs.

Broadleaf Wild Leek, an Early-Spring Woodland Native

One of the first plants to emerge

NC State Extension: one of the earliest edible plants to appear in the woodland each spring.

Forms dense woodland patches

A clumping, bulb-forming perennial that spreads slowly into dense colonies beneath deciduous trees.

The 'broadleaf' form's red-tinged stem

The broadleaf form (var. tricoccum) has a distinctive red-pigmented leaf stem, distinguishing it from the green-stemmed narrowleaf form (var. burdickii).

Flowers after the leaves die back

NC State Extension: small white flowers appear on a leafless stem after the foliage begins declining.

Three-seeded fruit gives it its name

The species name tricoccum means 'three-seeded', referring to the plant's distinctive black, three-lobed berries.

   Common names: ramps, ramson, spring onion, wild leek. Native to eastern North America (Quebec to Georgia, west to Minnesota). Dappled sunlight to deep/partial shade (2-6 hours direct sun). Soil high in organic matter, good drainage, consistent moisture, decomposed leaf litter. Spacing under 12in apart, bulbs planted about 3in deep. Height 6-12in, spreads 1-2ft wide, medium growth rate. Clumping herbaceous perennial, 2-3 tulip-shaped basal leaves from conical bulbs. Propagated by division or seed (seed may take 2 years to germinate); spreads via bulblets. Small white flowers on a leafless stem in spring after foliage begins declining. Harvested in early spring, one of the earliest edible plants to emerge. Bulb mites; bulb rot in overly wet soils. Leaves, stems and bulbs have a garlic-onion flavour, high in vitamin C.
