Oxalis dillenii aka Common Yellow Wood Sorrel

Taxonomy

Oxalis dillenii, also known as the southern wood-sorrel, slender yellow woodsorrel, and Dillen's oxalis, is a species in the wood-sorrel family Oxalidaceae in the genus Oxalis. This plant has leaves that resemble clover leaves, with three leaflets, and it produces flowers with five yellow petals that are 4 to 10 millimetres (0.16 to 0.39 in) in length. The leaflets are 1 to 2 centimetres (0.39 to 0.79 in) wide and have pointed hairs, while the fruits are rather brown and 1.5 to 2.5 centimetres (0.59 to 0.98 in) in size. It is often considered a weed and can be found worldwide, but it likely originated in North America. This plant can be either perennial or annual, and it has a thinner rhizome and outside-of-the-ground stolons. It is a widespread invasive species that infests vegetable crops, orchards, and is sometimes found in field crops. It is especially invasive in Kentucky. To get rid of it, manual weeding is recommended. Southern Woodsorrel is also a rare houseplant that requires regular watering to thrive. It prefers long-lasting, direct light and should be less than 1 foot from a window. The plant likes soil that is well-draining and does not require added fertilizers if you repot it each time it doubles in size.
