Purple leaved variety.
Oxalis corniculata, the creeping woodsorrel, procumbent yellow sorrel[2] or sleeping beauty, is a somewhat delicate-appearing, low-growing herbaceousplant in the family Oxalidaceae.
Oxalis corniculata is a small creeping type of woodsorrel that tends to grow well in moist climates.[3] It resembles the common yellow woodsorrel, Oxalis stricta.
Description
Stems with leaf stalk and side leaf (inconspicuous stipules at the base of each petiole are visible too)Trifoliate leaf of Oxalis corniculata
It has a narrow, creeping stem that easily takes root at the nodes. Its trifoliate leaves are subdivided into three rounded leaflets, resembling a clover. Some varieties have green leaves, while others, such as Oxalis corniculata var. atropurpurea, have purple leaves. There are inconspicuous stipules at the base of each petiole. The small, yellow flowers have either round-edged or sharp-ended petals. The flowers close when the plant is not within direct sunlight, hence the name "sleeping beauty". Some specimens can have a single flower while others can have over 20.

The fruit is a narrow, cylindrical capsule, 1–2cm (0.4–0.8in) long, and noteworthy for its explosive discharge of the contained seeds, 1mm (0.04in) long.[4] Pollen is about 34 microns in diameter.
Distribution
This species probably comes from southeastern Asia.[5] It was first described by Linnaeus in 1753[6] using specimens from Italy, and it seems to have been introduced to Italy from the east before 1500.[5] It is now cosmopolitan in its distribution and is often regarded as a weed in gardens,[7] agricultural fields, and lawns.[8]
Chloroplast genome
The chloroplast genome sequence is 152,189 bp in size, and contains 131 genes. It includes a pair of 25,387 bp inverted repeats that separate a large 83,427 bp single copy region. The genome suggests that this plant is closely related to O. drummondii.[3]
Uses
The leaves of this species are edible, and have a tangy taste like lemons. A drink can be made by infusing the leaves in hot water for about 10 minutes, sweetening, and then chilling.[9] The entire plant is rich in vitamin C. Any woodsorrel is safe in low dosages, but if eaten in large quantities over a length of time can inhibit calcium absorption by the body.[9]
Indigenous peoples of Taiwan frequently grow this plant (known roughly as p-r-səʔ) as a cure for snakebites and scabies.[10]
