Oxalis stricta L.Oxalis europaea
Wood Sorrel (Oxalidaceae)
Yellow Wood Sorrel is a perennia or annual reproducing by seed, clover-like in appearance and reaches a height of 6-12 inches. Leaflets are grouped in clusters of three and may hang inverted. The root system consists of underground runners. Flowers are 1/4-1/2 inch wide and are yellow in color. Flowering occurs during the months of June-August.
The plant is found commonly throughout the state of Wisconsin. It often can be found growing along roadsides and in gardens. It prefers moist, well-drained soils. It is commonly found growing in new plantings and in bare areas in established cranberry beds. It does not seriously compete with cranberry vines and often is eliminated as vine densities increase.
