Bloodroot (Sanguinaria canadensis) is actually an herb; despite its name. That is to say, it is a perennial that grows above the ground with a non-woody stem. However, it is the Bloodroot that is the most useful. The flowering part of Bloodroot is native to central and eastern North America from Canada to the Gulf of Mexico, it is unique in that it is pollinated not by bees or even birds, but by ants, which carry home the seeds to their nests, where they germinate. Because of its color, Bloodroot has been used as dye clothing.
