Creeping Woodsorrel
About this plant
Oxalis corniculata, commonly known as Creeping Woodsorrel, is a low-growing plant with small, clover-like leaves and tiny yellow flowers. It spreads quickly across the ground, often forming a dense mat. It is sometimes considered a weed but can also be grown as a ground cover. The plant has a sour taste due to oxalic acid and has been used in traditional remedies.
