Abstract
Canadian wild ginger (Asarum canadense L. [Aristolochiaceae]) is found in a variety of deciduous and moist coniferous forests throughout eastern Canada and the US. Because of the recalcitrant nature of Asarum seeds, we vegetatively propagate this species by divisions under natural shade at the Lake County Forest Preserve nursery in Illinois. This method yields plants suitable for outplanting in 3 y. We also use natural shade under established oak trees for native seed production, and an artificial shade bed system to produce 75 native woodland species found in the midwestern US.
