About

Oxalis debilis, the large-flowered pink-sorrel or pink woodsorrel, is a perennial plant and herb in the family Oxalidaceae. Its original distribution is South America but it has become a cosmopolitan species, occurring in all continents except Antarctica. It can be found in both temperate and tropical areas.

The flowers, leaves and roots are edible. The plant contains oxalic acid, which can cause calcium deficiency if eaten in larger amounts, but typical quantities of the plant would likely not be enough to cause this effect.

How to grow it

There are two varieties:

Oxalis debilis var. corymbosa (DC.) Lourteig – large-flowered pink-sorrel (Synonym : O. corymbosa)

Where it grows

Its original distribution is South America but it has become a cosmopolitan species, occurring in all continents except Antarctica. It can be found in both temperate and tropical areas.

Uses

The flowers, leaves and roots are edible. There is concern that the plant should only be consumed in small amounts because it contains oxalic acid, which can cause calcium deficiency if eaten in larger amounts. Studies show that this is an exaggerated fear.
