Cleavers (Galium aparine)

  • Kwitnące Flowering
  • White

Bedstraw family (Rubiaceae)

 

Annual of branched prostrate or climbing stems 50-150 cm long. Often forms mats. Roughly hairy throughout, hence marked capacity to adhere to material, skin, etc. Stem of square profile. 6-8 leaves per whorl. Flowers small, greenish-white, in clusters of 2-3 that grow up out of leaf axils. Globular burr-type fruits hooked, and so readily dispersed by animals on fur (zoochory). Flowers Jun.-Aug.

Grows on moist to mesic, nutrient-rich soils, in riparian forest or on margins of oak-lime-hornbeam forest. Nitrogen-demanding, ruderal weed of worldwide distribution. Young stems edible, while fruits provide “coffee substitute”.
