Oxalis is a large genus of flowering plants in the wood-sorrel family Oxalidaceae comprising about 570 species. They are annuals or perennials, with leaves divided into three to ten or more obovate and top notched leaflets, arranged palmately with all the leaflets of roughly equal size. The majority of species have three leaflets - in these species, the leaves resemble to those of some clovers. The flowers vary from white to pink, red or yellow. Several species are grown as pot plants or as ornamental plants in gardens, for example, O. versicolor. Oxalis flowers range in colour from whites to yellows, peaches, pinks, or multicoloured flowers. Some varieties have double flowers, for example the double form of O. compressus. Some varieties are grown for their foliage, such as the dark purple-leaved O. triangularis. Species with four regular leaflets – in particular O. tetraphylla -the four-leaved pink-sorrel – are sometimes misleadingly sold as "four-leaf clover", taking advantage of the mystical status of four-leaf clover.

Identify my woodsorrel

Option 1: Look at the merchant's label; Option 2: The oxalides carry 3 or 4 more or less heart-shaped leaflets, and white, yellow, mauve or red five-petalled flowers.

Plant my woodsorrel

Oxalides are found in tubers or scoops. Plant preferably in spring, in the open-soil if your climate is mild, otherwise in pot for the species that you will have to shelter: Oxalis triangularis, Oxalis brasiliense and Oxalis tuberosa. Oxalides like a light soil, fresh and humus. Bury the tubers 5 to 10 cm, and space them about twenty centimeters. In pots, mix soil, decomposed compost and sand in a pot of 3 liters.

Weed my woodsorrel

In perennial species, weeding also means working your flowerbed – don't let anything develop too quickly to the detriment of others.

Water my woodsorrel

Water during the summer season, once a week in case of dry weather, in the morning if possible. Water also during first month after planting, twice a week.

Propagate my woodsorrel

This should not be necessary: the oxalides multiply quite efficiently without outside help!

Mulch my woodsorrel

Each year, renew the mulch layer around your oxalis in the spring. It will help flowering by enriching the soil.

Fertilize my woodsorrel

A small glass of compost juice diluted to 10% - with 90% water - every week in the summer, and presto!

Protect my woodsorrel

Oxalis triangularis, Oxalis brasiliense and Oxalis tuberosa need to be sheltered in winter, protected from light, dry and cool. You have trouble recognizing them? - Oxalis triangularis has purple leaves with triangular leaflets. - Oxalis brasiliense has pink, red and then purple flowers. - Oxalis tuberosa is grown in the kitchen garden to eat its tubers, and it is one meter wide. If you do not want to shelter them, eat them ;-)
