is a dioecious perennial herb originating in Eurasia; it grows
wild on roadsides or in wastelands in various districts; 20-50cm in
height, more diminutive than another species, Rumex acetosa, it
propagates by extending its thin rhizomes sideways. Leaves measure
2-7cm in height, in the shape of a hastate, and bases project in a
pair of ears way. With this species, the female flower's inner
perianth lobes stay the same size even after the flower, unlike
Rumex acetosa. Bloom time: May-August.
