PROCUMBENT YELLOW SORREL – Oxalis corniculata: Oxalidaceae
The plant: this is a small plant, creeping and hairy. Usually seen in dry bare areas – this specimen was photographed on a hard, stony track. It is usually a garden escapee – bit it is highly successful in escaping. Those I have seen are never more than about six or seven cm tall. The plant is an annual, forming each year from seed, but sometimes it forms a new plant from the stems of an existing plant.
The flowers: the bright yellow flowers are about six mm across. There are five petals and the flowers can be seen all summer.
The leaves: trifoliate and clover-like. The leaflets are notched imparting a heart shape to them.
Names, mythology, uses and folk-lore: the leaves are said to have a tangy flavour to them because of the oxalic acid found within them. Little is written about its herbal properties. The plant can become an invasive garden weed if not controlled (by pulling out) – and is spreading successfully in the wild.
