description Bloodroot Overview

Bloodroot (Sanguinaria canadensis) is a perennial, spring-blooming herb native to the moist, deciduous woodlands of eastern North America. The plant is named for its thick, toxic rhizome, which exudes an orange-red latex sap when cut, a substance historically used by Indigenous peoples as a dye and traditional medicine. It produces large, multi-petaled white flowers that emerge early in the spring before the forest canopy fully develops. After setting seed, the plant naturally goes dormant and disappears by mid-summer.

help Bloodroot FAQ

Is bloodroot poisonous to touch or eat?

Bloodroot (Sanguinaria canadensis) is toxic if ingested; its orange-red sap contains the alkaloid sanguinarine. Handling the plant is generally fine, but the roots should never be eaten and home remedies applied to the skin can cause serious damage.

Why is bloodroot called bloodroot?

The name comes from the thick rhizome, which exudes a deep orange-red latex sap when cut. Indigenous peoples of eastern North America historically used that sap as a dye and body paint.

When does bloodroot bloom?

It blooms in very early spring, roughly March through May depending on latitude, with white petals that open on sunny days. As a spring ephemeral of eastern North American deciduous woodlands, it goes dormant and disappears by midsummer.

How do I grow bloodroot in a garden?

Plant the rhizomes in moist, humus-rich soil in part to full shade, mimicking the woodland floor it comes from. Given cool spring conditions and leaf litter, it naturalizes slowly over the years.

How are bloodroot seeds spread?

Bloodroot seeds carry elaiosomes, nutritious attachments that ants collect and carry back to their nests, effectively planting the seeds. This ant-mediated dispersal, called myrmecochory, is characteristic of many spring woodland wildflowers, and bloodroot belongs to the poppy family (Papaveraceae).
