In the city

In an urban environment, field bindweed is commonly found at the roadside, on dumps/wasteland and in gardens. It has long been associated with human habitats (synanthrope). In gardens and fields, it is an unwanted weed, because it climbs on other plants and inhibits their development.

Fun Facts

  • The plant’s roots can extend more than two metres into the soil and they can regenerate very well.

  • It flowers from June to September.

  • Endangerment level Germany: not endangered

  • Field bindweed has long been known as a medicinal plant. Its sap was used as a laxative.
