In the city

The broad-leaved willowherb often grows on nutrient-rich soils at the edges of forests, in clearings and under bushes. In inner cities, it is often found in gardens and parks.

Fun Facts

  • The flowering period is from June to September.

  • The plant mainly pollinates itself. Flies and butterflies rarely visit the flowers.

  • The broad-leaved willowherb lives for several years and generally flowers and fruits annually (perennial plant).

  • In autumn, the mother plant dies. Hibernation then takes place through underground renewal processes.

  • The silk-like appendages on the seeds serve for wind dispersal.

  • Endangerment level Germany: not endangered
