General Information

Oxalis tetraphylla is a perennial plant growing about 15cm tall and spreading by means of a running rootstock to form quite large clumps.
The plant is gathered from the wild for its edible leaves and flowers, which are consumed locally.

Known Hazards

The leaves contain oxalic acid, which gives them their sharp flavour. Perfectly all right in small quantities, the leaves should not be eaten in large amounts since oxalic acid can bind up the body's supply of calcium leading to nutritional deficiency. The quantity of oxalic acid will be reduced if the leaves are cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition[

Propagation

Seed - best sown as soon as ripe. Prick out the seedlings into individual pots when they are large enough to handle and plant them out when large enough.
Division, preferably when dormant. Larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade until they are well established before planting them out.
