Canadian Wild Ginger

Asarum canadense (ah-SAR-um ka-na-DEN-see)

Family: Aristolochiaceae Native Herbaceous (1-3 ft)

Canadian wild ginger is an herbaceous perennial wildflower in the pipevine family (Aristolochiaceae). It is native to a vast area of eastern North America. The species epithet is Latin for β€œof Canada.” Canadian wild ginger has poor drought tolerance and performs best in high organic matter soil that maintains constant moisture. This plant prefers light to deep shade, and it is often found on rocky, acidic soils. It spreads slowly and can be propagated through its underground rhizomes or through seeds. The tiny brown-purple flowers are hidden under the leaves and are more interesting than beautiful, but they do attract pollinators with their sweet fragrance. They are also capable of self-pollinating. The handsome foliage and high shade tolerance make it a great choice for a woodland, shade or rain garden. Plant it as an edging or border plant, and it will easily naturalize as a deciduous groundcover in your garden. This plant tolerates deer browsing, wet soils, heavy shade and erosion. Insects, Diseases, and Other Plant Problems: Slugs and snails can be occasional pests. More information on Asarum .
