This species is the only one in its genus which is part of the poppy family. Snow poppy hails from the woodlands of Eastern China. It is a rhizomatous (spreading though not invasive) plant that bears small pure white poppy-like flowers from late spring to summer. It has dull green, almost circular leaves that are toothed at the margins. Can be used as a ground cover on shady banks. Part shade is best in moist but well-drained soil. Can be grown in sun if adequate moisture is available.
