Oxalis corniculata – Yellow Wood Sorrel / Sour Clover
Oxalis corniculata, commonly known as yellow sorrel, garden sorrel, sour clover, wild sorrel, creeping woodsorrel, yellow woodsorrel, procumbent yellow sorrel, or sleeping beauty, is a creeping perennial plant from the Oxalidaceae family.
It has slender stems that spread along the ground and root at the nodes. The leaves are trifoliate (clover-shaped), deep green, and close at night or in cloudy weather (hence the name “sleeping beauty”). The flowers are small and yellow, with 5 petals, and appear abundantly throughout the growing season. The leaves and flowers have a sour, lemon-like taste due to their oxalic acid content.

📌 Note
The foliage coloration is variable and is one of the cultivar’s characteristics. The same plant may simultaneously display lime-green, golden, bronze, copper, or pinkish-red leaves. The intensity and proportion of these shades are influenced by light, temperature, season, and leaf age. The plant may therefore look different from the presentation photographs.
The plant may be delivered with or without flowers, depending on its stage of development. The stems and leaves are delicate and may have breaks, dried leaves, or other minor aesthetic imperfections as a result of handling, transport, or adaptation to new environmental conditions, without affecting the plant’s viability.
