Paeonia anomala

Paeonia anomala is a species of herbaceous perennial flowering plant in the family Paeoniaceae. This peony is ½–1 m high, with a thick irregular taproot and thin side roots. The deeply incised leaves have leaflets which are themselves divided in fine segments. It flowers in early summer, almost always with only one fully developed flower per stem, usually magenta-red or more rarely, pink or white. The species occurs in a zone between northern European Russia and northern Mongolia and south to the Tien Shan Mountains. In garden cultivation, it requires full sun or half-shade and well-drained soil. Double-flowered forms are found in cultivation....read more on Wikipedia.
