What is Oxalis corniculata?
Oxalis corniculata, also known as creeping woodsorrel or yellow wood sorrel, is a persistent little plant that can be both charming and frustrating. I first encountered it in my garden, its small yellow flowers peeking out from amidst the greenery. At first, I found it quite lovely, adding a pop of color to the landscape. However, as it began to spread rapidly, I realized it was becoming a nuisance.
569 Species in Genus Oxalis
Creeping woodsorrel is characterized by its clover-like leaves, which consist of three heart-shaped leaflets that fold down at night or in low light conditions. It produces small, yellow flowers with five petals that bloom throughout the growing season. The plant spreads rapidly via creeping stems (stolons) and can quickly colonize lawns, gardens, and other disturbed habitats.
While Oxalis corniculata is considered a weed in many areas due to its aggressive growth habit, it is also valued for its edible leaves, which have a tangy flavor and are sometimes used in salads or as a garnish. However, it should be consumed in moderation due to its oxalic acid content, which can be harmful in large quantities.
In addition to its culinary uses, Oxalis corniculata has also been used in traditional medicine for various purposes, including treating skin conditions, fevers, and digestive issues. However, it is important to use caution when consuming or using this plant for medicinal purposes, as it may have toxic or irritant properties in some individuals.
