Oxalis lasiopetala, commonly known as Pink-Sorrel, Pink Oxalis, or Pink Wood-Sorrel, is a perennial herb native to open woodlands and grassy areas in South America, particularly Brazil and Argentina. It has a moderate growth rate, reaching a height and width of 0.5-1 feet (0.15-0.3 meters). This plant is characterized by its clover-like foliage and delicate, pink, funnel-shaped flowers that are quite showy and bloom profusely in the spring and summer months. The foliage may close at night or on cloudy days, adding a dynamic aspect to its appearance.

Pink-Sorrel is valued for its ornamental flowers and its ability to fill in spaces as a ground cover. It is often used in border plantings, rock gardens, and as an underplanting for taller perennials. It thrives in full sun to part shade and prefers medium or fast-draining soils, including clay, loam, or sandy types. Regular watering is necessary, especially in dry conditions. While it is generally low maintenance, it can spread rapidly via bulbs and self-seeding, which may be a concern in some areas. Gardeners should be aware of its potential invasiveness when grown outside its native range and check local regulations before planting.CC BY-SA 4.0
