This is a small, creping plant able to cover extensively the floor of coniferous and mixed forests, with a wide distribution in the Northern hemisphere. It flowers early, often in May. The entire plant contains oxalic acid that imparts a tangy taste to it and children love to chew the fresh plants in spring.

Assured the foliage is entirely harmless and quite refreshing in early spring. I remember as a child we sought out these leaves and devoured them eagerly for their tangy taste. Made a perfect mix with sweetness of the young inflorescences of Noccea caerulescens (syn. Thlaspi alpestre), which often was found in the vicinity.

 

When the wood sorrel matures, the texture of the foliage becomes denser and less tempting to eat, plus the acidity increases to make eating the plant a doubtful experience. You learn quickly as a child.
