Sanguinaria canadensis
An eastern North American woodland perennial with white flowers and red sap, spreading via rhizomes to form colonies, historically used for dyes and medicines due to alkaloids such as sanguinarine and noted for its toxicity.
Common Names

Summary
Bloodroot is a native eastern North American perennial forb in the Papaveraceae family. It is rhizomatous and forms large colonies on the forest floor, reaching about 6–10 inches tall with a single basal leaf that is palmately lobed and a solitary white flower with a yellow center on a separate stalk; stems and rhizomes exude a bright reddish-orange sap. Flowers bloom in early spring and close at night, while foliage persists into summer, providing distinctive blue-green leaves as a backdrop for the bloom. Cultivation favors moist, humus-rich, well-drained soils in part to full shade, and it spreads to form colonies. Propagation is by seed or rhizome division; seeds may require cold stratification and germination can be slow, with division possible in autumn or spring. Mulching year-round is recommended; handle with gloves due to the caustic, poisonous sap. Bloodroot carries historic value as a dye and in traditional medicine, and remains an ornamental woodland plant suitable for native plant and rock gardens in properly shaded landscapes.
