Canadian wild ginger serves as a nesting ground for the pipevine swallowtail butterfly, Battus philenor, to lay eggs. It is used as a host and food source for the maturing larvae. The butterfly is most common in the southwest during late summer and fall, but c Courtesy of Wikipedia Commonsan be found to inhabit areas as north as Massachusetts. Occasionally there are strays found in Canada, but most of the butterflies lay their eggs on Asarum canadense plants that are farther south.

Asarum canadense is a plant that sits very low to the ground, and for very good reason. Pollination is assisted via beetles, flies, and ants that crawl by. The insects are attracted to the aroma of the flower. However, if cross-pollination does not occur, Asarum canadense is capable of self-pollinizing.

A very common interaction that occurs in 80% of plants is that with mycorrhizae, a fungus. The relationship between Asarum canadense and mycorrhizae is mutually beneficial. The presence of mycorrhizae improves the transport of minerals in the plant because the vast mycelial networks of the fungi are more efficient in obtaining minerals from the soil than the roots of the plant. It also increases the surface area of the roots. The fungi benefits by receiving sugars that are produced by the plant.
