Red sorrel is a perennial herb that can reach 1.6 ft. (0.5 m) in height. Leaves are alternate, petiolate, glabrous, entire, 3-lobed, up to 1.2 in. (3 cm) long and occur in a basal rosette. Flowering occurs from March to November, when yellowish-green flowers (male) or reddish (female) flowers develop in clusters of a branched inflorescence at the apex of the stem. Flowers are typically drooping and have 3 petals and 3 sepals, each less than 1/10 in. (1-1.5 mm) long. Fruits are red achenes. Red sorrel is native to Europe and occurs along roadsides and other disturbed areas. |
