Oxalis debilis aka Pink Woodsorrel

Oxalis debilis, also known as the large-flowered pink-sorrel or pink woodsorrel, is a cosmopolitan perennial plant and herb in the family Oxalidaceae. Originally from South America, it can now be found in temperate and tropical areas on all continents except Antarctica. The plant has edible flowers, leaves, and roots, which have a zesty lemony flavor. Although it contains oxalic acid, studies show that the fear of calcium deficiency from consuming the plant in larger amounts is exaggerated. Pink Woodsorrel can also be grown as a rare houseplant that requires regular watering and well-draining soil. It thrives in direct light and should be placed less than 1 foot from a window. Repotting each time the plant doubles in size eliminates the need for added fertilizers. To remove Pink Woodsorrel from outdoor areas, manual weeding is recommended.
