Answer:
poppy
The only species in the genus Sanguinaria (Latin for "bloody"), bloodroot belongs to the family Papaveraceae, also known as the poppy family. This plant, which is also called by the common names of bloodwort, redroot, and Canada puccoon, is a flowering perennial that produces beautiful (though short-lived) white flowers in the early spring. As its names imply, the plant's rhizome and its sap are red in colour. Both the rhizome and the leaves are toxic because of their high alkaloid content; in addition, applying bloodroot extracts to the skin causes disfiguring lesions, and its home use to treat certain skin cancers is discouraged. In spite of that, the medicinal use of bloodroot was widespread in the past, especially among Native American peoples. Bloodroot juice is also used to make red, pink, and orange dyes, often used by Native American craftspeople; gloves should always be worn when handling these plants.
Since World War I, the common, or corn, poppy (Papaver rhoeas) has been a symbol of remembrance for those fallen in war - a tradition inspired by Canadian poet John McRae's poem, "In Flanders Fields".
