Wood sorrel (Oxalis acetosella)

  • Kwitnące Flowering
  • White

Wood sorrel family (Oxalidaceae)

Small, delicately downy perennial, of heights 5-15 cm. Flower pedicels and leaves grow up from thin, creeping rhizome. Compound leaves of three leaflets pale green and long-stalked. Flowers white with veins, arranged singly, on hairy pedicels. Seeds expelled for distances of around 2 m. Flowers Apr.-Jun.
Grows on mesic to moist, nutrient-poor to nutrient-rich soils. Hence broad ecological amplitude, though shade-tolerant and will grow in mixed/coniferous, oak-lime-hornbeam, riparian and alder forests, as well as in boreal spruce forests on bogs. Edible, despite content of oxalic acid. Leaves ”close up”, i.e. fold down, for the night.
