Bloodroot

There are about 500 species in this large genus, which is distributed throughout the northern hemisphere. Most are perennials or shrubs, with some annuals, and biennials, and many are found on heaths and in woodland. Several species are used medicinally for their high tannin content, which in P. erecta approaches 20 percent. These include P. anserina (silverweed) and P. reptans (creeping cinquefoil, fiveleaf grass), which contains less tannin but are still useful astringents. Potentilla means "powerful", from the Latin potens, alluding to the plant's curative powers.

Perennial with a thick, woody rootstock, red inded, and slender, branched stems, bearing 3-lobed basal leaves and 5-lobed stem leaves. Small, bright yellow, 4-petaled flowers are borne from early summer.
