Wood sorrel

An edible plant in the shape of a heart
Klaverzuring
Wood sorrel does well in open ground, in pots on your balcony or the kitchen windowsill. It's an unusual herb, that will brighten up everyday salads.

Care

  • Many wood sorrel types are sensitive to frost and therefore very happy in pots. 
  • Likes to be in partial shade.
  • Wood sorrel blooms in the summer months.
  • Water the plant regularly, as it drinks a lot.
  • Likes light, lime-poor soil.

Colours and shapes

Wood sorrel, whose botanical name is Oxalis, has clover-shaped leaves that come in green, green-purple, and purple-grey. The flowers that bloom on the plant are either white, pink, yellow or red. Both leaf and flower close up at night, ready to greet the world once more, the following morning. 

The leaves, flowers and stems of this plant are all edible, and have a sharp citrus lime flavour.  Use the flowers to elevate a starter or salad, and cook the leaves and stems in a stew to boost flavour.

Origin

Wood sorrel is found all over the world. Oxalis is derived from the Greek oxus or oxys (acid), and wood sorrel gets its name from the leaves that contain oxalic acid as a self-defense. That's where the slightly sour taste comes from.

Trivia

Thanks to its heart-shaped leaves, the white wood sorrel competes with the more traditional clover for the position of the real-life Irish shamrock.
