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.
