What is Oxalis Weed?

These plants are gross annual or perennial. The leaves are split into three to ten or more obovate and top notched leaflets, arranged palmately with the leaflets of roughly equal size. Nearly all species have three leaflets; in these species, the leaves are superficially similar to those of some clovers.[4] Some species exhibit rapid changes in leaf angle in response to temporarily high light intensity to diminish photoinhibition.

The flowers have five petals, which are usually fused at the base, and ten stamens. The petal color varies from white to pink, red or yellow[6]; anthocyanins and xanthophylls could be present or absent but aren't both present together in significant quantities, meaning that few wood-sorrels have bright orange flowers. The fruit is a little capsule containing several seeds. The roots are often tuberous and succulent, and many species also reproduce vegetatively by production of bulbils, which detach to create new plants.
Several Oxalis species dominate the plant life in local woodland ecosystems, be it Coast Range ecoregion of the North American Pacific Northwest, or the Sydney Turpentine-Ironbark Forest in southeastern Australia where least yellow sorrel (O. exilis) is common. In the United Kingdom and neighboring Europe, common wood sorrel (O. acetosella) may be the typical woodland person in this genus, forming large swaths in the typical mixed deciduous forests dominated by downy birch (Betula pubescens) and sessile oak (Quercus petraea), by sycamore maple (Acer pseudoplatanus), common bracken (Pteridium aquilinum), pedunculate oak (Q. robur) and blackberries (Rubus fruticosus agg.), or by common ash (Fraxinus excelsior), dog's mercury (Mercurialis perennis) and European rowan (Sorbus aucuparia); additionally it is common in woods of common juniper (Juniperus communis ssp. communis). Some species - notably Bermuda-buttercup (O. pes-caprae) and creeping woodsorrel (O. corniculata) - are pernicious, invasive weeds when escaping from cultivation outside their native ranges; the power of all wood-sorrels to store reserve energy within their tubers makes them quite resistant to most weed control techniques.

Tuberous woodsorrels provide food for several small herbivores - including the Montezuma quail (Cyrtonyx montezumae). The foliage is eaten by some Lepidoptera, such as the Polyommatini pale grass blue (Pseudozizeeria maha) - which feeds on creeping wood sorrel and others - and dark grass blue (Zizeeria lysimon).

Wood sorrel (a type of oxalis) can be an edible wild plant that has been consumed by humans all over the world for millennia.[7] In Dr. James Duke's Handbook of Edible Weeds, he notes that the native American Kiowa people chewed wood sorrel to ease thirst on long trips, the Potawatomi cooked it with sugar to create a dessert, the Algonquin considered it an aphrodisiac, the Cherokee ate wood sorrel to alleviate mouth sores and a sore throat, and the Iroquois ate wood sorrel to greatly help with cramps, fever and nausea.

The fleshy, juicy edible tubers of the oca (O. tuberosa) have long been cultivated for food in Colombia and elsewhere in the northern Andes mountains of SOUTH USA. It really is grown and sold in New Zealand as "New Zealand yam" (although not a true yam), and varieties are actually obtainable in yellow, orange, apricot, and pink, in addition to the traditional red-orange.
