Rumex acetosa is a
dioecious perennial herb, growing 0.3-1 m tall, commonly found in
grasslands, along paths between paddies, or on roadsides. Leaves are
about 10cm long, oblong-lanceolate, with the bases generally
sagittate; the upper parts embrace the stems. The stem tips bear
conical racemes with many small flowers, about 3mm across. The
female flower's inner perianth lobes become wing-like, embracing the
achenes. Bloom time: May-August.
