Agrimonia pilosa

Agrimonia pilosa, hairy or Asian agrimony, is an erect perennial herb in the family Rosaceae, growing 30 to 120 cm tall from a short woody rhizome. It occurs across temperate East Asia, including the Korean Peninsula, Japan, China and the Russian Far East, with a continuous range extending westward through Siberia into eastern Europe. The stems are pubescent, more densely so toward the base, and bear alternate, odd-pinnate leaves with two to four pairs of major leaflets interspersed with smaller secondary leaflets along the rachis; the leaflets are ovate-elliptic, coarsely serrate and softly hairy beneath. Long, slender, terminal racemes of small, five-petalled yellow flowers open from late spring through summer, each subtended by a small bract. Fruits are dry hypanthial achenes crowned by a ring of hooked bristles that adhere to fur and clothing, aiding dispersal. The plant typically grows along roadsides, woodland margins and damp grasslands on a wide range of soils and pH conditions.
