Canada wild ginger

Asarum canadense Aristolochiaceae

Canada wild ginger is a low woodland groundcover with pairs of large, velvety, kidney-shaped leaves on hairy stalks about 15 cm tall. A small brownish-purple, three-lobed flower sits at ground level between the leaf stalks in spring, so it is easily missed. Fleshy shallow rhizomes knit the plants into a slow, dense carpet. The leaves die back in winter.

Story

The history of canada wild ginger.

Wild ginger grows in the understory of deciduous forests across eastern North America, from the Great Plains to the Atlantic coast and from southeastern Canada south to the Fall Line. Its seeds carry an oil-rich appendage that ants eat, and the ants carry the seeds up to about 36 metres from the parent. The seeds need warm and then cold periods before they germinate, and the plant spreads mostly by rhizomes.

Wild ginger holds a place in Haudenosaunee and Anishinaabe knowledge as a seasoning, a ceremonial plant and a medicine, and many nations recorded its use. The roots contain aristolochic acid, so eating the plant is not recommended. It is now widely suggested as a native shade groundcover.

Care

What to do, season by season.

Spring

Plant in humus-rich soil and keep moist while roots settle. Watch for slug damage on new leaves.

Summer

Water in dry spells; the plant wilts in dry shade.

Fall

Leave fallen leaves as mulch. Divide rhizome pieces with a dormant bud if you want to extend the patch.

Winter

Leaves die back; a leaf mulch protects the rhizomes.

Relations

Knowledge and use.

The Greenbelt Indigenous Botanical Survey describes wild ginger as a cultural keystone species for Indigenous peoples of the Great Lakes region, used as a flavouring and for spiritual protection, and records Alyssa General and Elder Brian Peltier speaking about its uses. It advises fall harvest only in small amounts because the rootstock supports both medicine and reproduction.
