About Watercress

Watercress is a peppery, nutrient-dense aquatic green that loves cool, running water and partial shade — an easy container crop if you keep it constantly wet.

Grow in a container of rich soil kept standing in water, refreshed regularly. Harvest outer leaves often. Prefers cool shade to hot sun.
