Safety & 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[1].

Cultivation Details

HabitPerennial
Growth—

Oxalis tetraphylla is not very cold-hardy, tolerating short periods with temperatures falling to between -5 and -10°c[2]. A very easily grown plant, preferring a sandy soil in a warm dry position[3]. Our plants have proved to be very tolerant of neglect, succeeding for a number of years even in the dense growth of grass weeds[PFAF]. When well-tended, clumps can spread quite quickly[PFAF].

Propagation

Seed - best sown as soon as it is ripe in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle and plant them out in late spring or early summer. Division in spring. 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 in a cold frame until they are well established before planting them out in late spring or early summer.
