Sanguinaria canadensis Linnaeus. Bloodroot, Red Puccoon. Phen: (Late Jan-) Mar-Apr; Apr-May. Hab: Moist nutrient-rich forests. Dist: NS west to MN and MB, south to Panhandle FL and OK.

Origin/Endemic status: Native

Taxonomy Comments: Fernald recognized two varieties – var. rotundifolia, more southern and the primary form in our area, considered to have leaves less lobed than the more northern var. canadensis; leaf shape variability within populations makes it impractical to recognize infraspecific taxa.
