| Identification | Sheep Sorrel is a familiar plant of weedy places owing to its long "spike" of dull reddish flowers. The stems are perennial and may grow to 1.5 feet tall, but usually less than a foot. The basal leaves are moderately long-stalked, the blades lance-shaped and with 2 lateral narrow lobes near the base. The stem leaves are similar but shorter-stalked. The inflorescences are axillary and terminal, slender or stringy looking, the flowers numerous in whorls of 5-8, reddish. In several respects it is a smaller version of the native A. hastatula, the major difference being the lack of sepal wings in A. acetosella. | |
| Taxonomic Comments | This and several other former Rumex taxa have been moved to Acetosa, by Weakley (2023).
