Overview

Watercress is a semi-aquatic plant from the Brassicaceae family, native to Europe and Central Asia. This nutritious plant is cultivated for its tasty, peppery leaves. Watercress is renowned for its high iodine content and vitamins.

Appearance and bloom

Watercress has thin, green stems with small, lobed leaves. The plant grows low, usually 20-50 cm tall. It blooms with small white or light pink flowers. The plant has creeping stems that readily form roots.

Ideal location

Watering

Keep the soil always very moist, almost waterlogged. In water culture, place the plant directly in running or still water. Regular misting helps ensure sturdier leaves.
