Watercress has a peppery flavour and is a delicious addition to salads.

The dark green leaves are rich in vitamins and minerals including iron and vitamins C. K and A.

Most of the plant can be eaten, leaves, stems and even the white flowers, all apart from the roots.

While commercially grown and wild watercress is grown in flowing water, it is very easy to grow at home as long as the soil is kept damp. It is easiest to grow it in a large pot or container.

If you don't have space outside, or in cooler weather, watercress can be grown on windowsills indoors.

Harvest the plants from the top when they are large enough. If you don't cut the plants too near to their base new side shoots should appear and give you fresh leaves.

Watercress attracts / provides food for the following creatures:

  • Hoverflies
  • Green-veined White butterfly 🐛 
  • An "RHS Plants for Pollinators" plant **
