Sanguinaria canadensis L.
Papaveraceae (Poppy Family)
Synonym(s): Sanguinaria canadensis var. rotundifolia
USDA Symbol: saca13
The single bloodroot leaf and flower each rise on a separate stem, and at first the leaf completely enwraps the flower bud. The clear, white, many-petaled blossom may open before the leaf has completely unwrapped, rising slightly above the leaf to a height of 6-10 in. Leaves, which are large, round and deeply cleft, eventually reach a height of 12-24 in. On a smooth stalk a solitary white flower, with a golden-orange center, grows beside a lobed basal leaf that often curls around the stalk. Roots and stem with acrid red-orange juice.
This fragile spring flower develops and rises from the center of its curled leaf, opening in full sun, and closing at night. Like most members of the Poppy Family, it lasts for a relatively short time. The red juice from the underground stem was used by Native Americans as a dye for baskets, clothing, and war paint, as well as for insect repellent. The generic name, from the Latin sanguinarius, means "bleeding."
