Bloodroot

Sanguinaria canadensis
Papaveraceae

Growth Habit

Herbaceous

Propagation

Seed Treatment and Storage: Keep seed moist. Needs warm then cold then warm moist stratification. Can take 2 years to germinate

Biocultural Value

Many Native American groups, including the Meskwaki, Haudenosaunee, and Omaha, used bloodroot as a dye. The roots also served medicinal purposes as an emetic, gastrointestinal aid, tuberculosis remedy and dermatological treatment for cuts, sores, and poison ivy.

Poisonous
Bloodroot is poisonous to both livestock and humans in large doses. Alkaloids are found throughout the plant that affect the nervous system. Ingestion causes vomiting and potentially a fatal coma in those that overdose.

Wildlife Value

Mining bees (Andrena spp.) collect pollen from bloodroot's nectarless flowers and serve as plant's primary pollinators. Sweat bees (Lasioglossum spp.) also collect bloodroot pollen. When pollinators are absent, the flowers will self-pollinate near the third day of flowering. The plant is a larval host for the southern armyworm (Spodoptera eridania) and the tufted apple bud moth (Platynota idaeusalis). Ants collect and disperse the dark brown seeds, which have a lipid-rich elaisome. An aphid (Linosiphon sanguinarium) sucks plant juices from the underside of bloodroot leaves, but most mammalian herbivores avoid the acrid foliage.
