Care of the plant Oxalis articulata or Pink-sorrel

The genus Oxalis, family Oxalidaceae, comprises 600 species of herbaceous plants native to temperate and warm regions of almost all continents. Some species are: Oxalis articulata, Oxalis pes-caprae, Oxalis triangularis, Oxalis bowiei, Oxalis purpurea, Oxalis flava, Oxalis acetosella, Oxalis corniculata, Oxalis gigantea, Oxalis rosea.

Common names: Pink-sorrel, Pink wood sorrel, Windowbox wood-sorrel, Sourgrass. This species is native to South America.

They are rhizomatous perennial herbaceous plants that reach 40 cm in height. They have deep green trifoliate leaves mottled with lighter green. They produce flower stems with various pink flowers. They bloom in spring and summer. The capsule-shaped fruits contain many seeds.

They are used in pots and planters, in light undergrowths and damp areas of the garden. The leaves can be eaten in salads.

The Oxalis articulata prefers a semi-shade exposure in very hot summer climates such as the Mediterranean and full sun if the summers are cooler. They resist occasional frosts.

They prefer well-drained (sandy) soil that contains organic matter. Planting is done in early spring.

Water frequently (without flooding) in spring and summer so that the substrate is always slightly damp. In winter reduce watering without allowing the substrate to dry out completely.

Fertilize monthly with mineral fertilizer during spring and summer.

They do not need pruning but their expansion must be monitored so that they are not invasive.

They are resistant plants to the usual pests and diseases.

They are easily propagated from seed sown in spring or by division of the rhizome in early spring.
