Watercress (Nasturtium officinale)

Plant Description

Watercress (Nasturtium officinale) is an interesting pond plant with attractive green leaves, hollow stems and little green and white flowers in summer. Watercress plants are semi-aquatic, edible and considered an herb or a vegetable. Tender new leaves or sprouts may be eaten on the Watercress plant. Watercress is considered one of the healthiest plants available to eat and is one of the oldest known vegetables consumed by humans. Watercress grows 18 - 36 inches tall in full sun to part shade. Only new growth is considered desirable on the Watercress plant (edible) as older growth becomes bitter. Watercress does well in container gardens when planted for consumption and looks pretty when planted in the pond as it softens the rockery.

Planting Instructions

Plant Watercress in very moist soil in your terrestrial garden or in containers to place in the pond with a couple of inches of water above the soil. Plant in full sun to part shade. Watercress may be grown in zone 3 as an annual or indoors with artificial light.
