This is the spring wildflower I always love to see because of the common name, Bloodroot. It just sounds so morbid. Indeed, if you break the tuberous root of this plant the sap is a bright blood red-orange color. The botanical name is Sanguinaria canadensis, which alludes to its blood-like qualities.The pure white flower has 8-12 petals around yellow anthers, often in a double row.
