Characteristics
R. acetosella is a perennial herb that has an upright stem that is slender and reddish in color, and branched at top, reaching a height of 18 inches (0.5 meters). The arrow-shaped leaves are simple, slightly more than 1 inch (3 cm) in length, and smooth with a pair of horizontal lobes at base. Flowers from March to November, when yellowish-green flowers (male) or reddish (female) flowers develop on separate plants, at the apex of the stem. Fruits are red achenes.
Sheep's sorrel is widely considered to be a noxious weed, and one that is hard to control due to its spreading rhizome. Blueberry farmers are familiar with the weed, due to its ability to thrive in the same conditions under which blueberries are cultivated. It is commonly considered by farmers as an Indicator plant of the need for liming.
