In the city

The common whitlowgrass prefers sandy or gravelly, open soils. Therefore, it often grows on fallow land and railway tracks, along paths, on walls and in pavement cracks. If the space is available, often numerous plants grow next to each other. It is light-loving.

Fun Facts

  • The seeds usually germinate only in winter.

  • The leaves wither before the fruits are ripe. However, the green fruits can photosynthesise themselves and thus form the seeds.

  • The flowering period is from March to May.

  • It is an annual plant, i.e. it flowers for only one summer and dies after the seeds have ripened.

  • The flowers are rarely visited by insects. Self-pollination, on the other hand, is frequent and is encouraged by closing the flowers during the night and when it rains.

  • Endangerment level Germany: not endangered
  • The common whitlowgrass originates from Europe and Asia.
