For those of us that hate weeds, woodsorrel sourgrass may look like a patch of much-hated clover. Although in the same family, it is a very different plant. There are numerous uses for yellow woodsorrel. Is yellow woodsorrel edible? This wild plant has a long history as a culinary herb and for medicinal use.

What are Sourgrass Plants?

Plants in the Oxalis genus are similar to clover but an entirely different family. Oxalis grows from little bulbils, while clover is a seeded or rhizomatous plant. Yellow woodsorrel (Oxalis stricta) appears like a small variety of clover but has none of the nitrogen fixing capabilities. There are several yellow woodsorrel benefits, though.

Woodsorrel sourgrass is a native North American plant. It is found from the Eastern U.S. into Canada. The plant has a long history as food and medicine to indigenous people. The plant is a perennial weed with three heart-shaped leaflets and produces a five-petaled, yellow flower from spring to fall.

Seeds form in hard little capsules which erupt when ripe and shoot seed up to 12 feet (4 m.) away. Each pod contains 10 seeds. The plant often colonizes vacant spots in the lawn and can grow up to 12 inches (30 cm.) tall. If you just can't live with this plant, either hand pull it or use a pre-emergent herbicide for woodsorrel weed control. Most herbicides are not useful against this weed.

The genus, Oxalis, means "sour." This is a reference to the tangy flavor of the leaves, stems, and flowers – hence its common name of sourgrass.

Woodsorrel also can be used as a flavoring in soups, stews, salads, and more. The plant contains oxalic acid, which can be toxic in high quantities but beneficial in smaller doses. The seed pods are also edible and may be ground as a spice and added to recipes.

The plant is also useful in treating scurvy, fever, urinary tract infections, sore throats, nausea, and mouth sores. It supposedly helps cleanse blood, and some believe it can help in cancer cases. The flowers are a historical source of orange-yellow dye.
