Watercress

Nasturtium officinale

Also known as: Nasturtium officinale, agrião, berro

A peppery semi-aquatic perennial of the mustard family, grown in flowing freshwater or wet soil since at least Roman times. Among the most nutrient-dense leafy greens by weight — high in vitamin K, vitamin C, and the bitter sulfur compounds that give the cabbage family its medicinal reputation.

Scientific

Nasturtium officinale (family Brassicaceae) is a perennial that grows naturally in clean cool flowing streams across Europe, North Africa, and western Asia, with naturalized populations worldwide. Hollow stems float; small white flowers cross in mid-summer.

Commercial production is done in flooded gravel beds with steady cold-spring flow — the model around Alresford in Hampshire (England) and around the Limmat valley (Switzerland) — or in flood-irrigated soil beds at lower water depth. Hydroponic production in greenhouses is increasingly common.

Cultural and historical

Watercress was a foraged green long before it was cultivated. Roman soldiers carried it as a scurvy preventative; medieval European kitchens used it in soups and pottages. Commercial bed-cultivation began in 19th-century England, where the dense network of chalk-stream watercress beds around Hampshire was a major industry feeding London. Watercress sandwiches — buttered white bread, salt, watercress — became a working-class staple and stayed so.

On the directory

Watercress appears across the [[cnpo-brazil|CNPO Brazil]] organic registry — agrião is a familiar Brazilian leafy green, especially in salada brasileira (Brazilian salads), in feijoada side dishes, and in fresh juices. Brazilian organic small farms produce significant watercress for urban markets.
