Identifying Wild Watercress


Wild watercress (Nasturtium officinale), also known as "Nasturtium" or "True Watercress," is an aquatic or semi-aquatic plant belonging to the Brassicaceae family. It is a hardy perennial with lobed, dark green leaves and small white flowers that bloom in clusters. The plant often grows in dense mats, spreading across the water's edge, with its leaves trailing in the water.

The leaves of wild watercress are pinnately compound, meaning they have several leaflets arranged on opposite sides of the stem, with one terminal leaflet at the end. Each leaflet is round to oval-shaped and has a characteristic peppery taste that intensifies as the plant matures. The small white flowers, which appear from spring to early summer, are delicate and give way to small, rounded seed pods.


Watercress Identification checklist


Leaf Structure: Watercress has distinct, lobed leaves that are pinnately compound, meaning they have multiple leaflets arranged on opposite sides of the stem. Each leaflet is rounded to oval-shaped and has a slightly glossy surface.


Leaf Arrangement: The leaves grow in pairs along the stem, with one terminal leaflet at the end. The leaf pairs alternate along the stem.


Leaf Edges: The leaflets may have slightly toothed or scalloped edges, giving them a delicate appearance.


Leaf Colour: The leaves of watercress are a vibrant dark green, which makes them stand out against the water's edge.


Flowers: In the spring and early summer, watercress produces small white flowers that grow in clusters. The flowers are delicate and have four petals.


Habitat: Watercress is semi-aquatic and is typically found along the edges of clear, cool, and fast-moving streams, rivers, and springs. It prefers well-oxygenated water.


Distinctive Peppery Taste: One of the most notable characteristics of watercress is its peppery taste. As you nibble on a fresh leaf, you'll experience a mild spiciness that intensifies as the plant matures. This unique flavour is one of the reasons watercress is sought after in culinary circles.

Confusing Look-Alikes


While watercress has distinctive features, it's essential to differentiate it from potentially toxic plants that might resemble it. One common look-alike is Hairy Bittercress (Cardamine hirsuta), which has similar leaf structures but lacks the peppery taste of watercress. Another potential confusion is with Marsh Marigold (Caltha palustris), which has glossy heart-shaped leaves and bright yellow flowers (and is poisonous).


Watercress Habitat and Foraging Locations


Wild watercress thrives in freshwater habitats with clear, cool, and fast-moving water, which is rich in nutrients. It is commonly found along the banks of streams, rivers, and springs, where the water is well-oxygenated. The plant prefers partially shaded areas, as direct sunlight can cause it to wilt.


The UK offers a wide array of locations where wild watercress can be found and foraged. Some popular regions include:


The River Itchen (Hampshire): The River Itchen in Hampshire is known for its abundance of wild watercress. In fact, the town of Alresford hosts an annual Watercress Festival, celebrating this delightful herb.


The River Kennet (Berkshire/Wiltshire): The River Kennet, flowing through Berkshire and Wiltshire, is another prime spot for finding wild watercress.


The River Wye (Wales/England): The River Wye meanders through both Wales and England, offering numerous opportunities to discover wild watercress along its course.


The River Tweed (Scottish Borders): Scotland is also home to wild watercress, and the River Tweed in the Scottish Borders is one of the places to find it.


The Norfolk Broads (Norfolk): The network of waterways in the Norfolk Broads is a promising location for foraging wild watercress.

Watercress Foraging Tips and Sustainability


When foraging wild watercress, it's essential to follow some best practices to ensure sustainability and respect for the environment:


Responsible Harvesting: Only pick small quantities of watercress, leaving the majority of the plant undisturbed. This allows the plant to continue growing and producing new shoots.


Avoid Pollution: Ensure that the water source from which you're harvesting is free from pollution and contaminants. Choose clean, clear water to avoid any health risks.


Permission and Regulations: If you plan to forage on private land or nature reserves, always seek permission and follow any regulations set by the landowners or conservation authorities.


Cutting Technique: Use scissors or a knife to cut the watercress stems just above the waterline. Avoid uprooting the entire plant.


Perfect for carrying your haul of foraged food, buy handmade willow baskets and trugs.


Edibility of Wild Watercress


Wild watercress (Nasturtium officinale) is not only visually appealing with its vibrant green leaves and delicate white flowers but also offers a delightful peppery flavour that sets it apart from other greens. This versatile plant is entirely edible and holds a special place in culinary traditions across the UK and beyond.

Culinary Uses of Wild Watercress


Wild watercress can be a refreshing and nutritious addition to a variety of dishes. Its peppery taste adds a delightful kick to both raw and cooked preparations. Here are some popular culinary uses of wild watercress:


Fresh Salads: The simplest and most popular way to enjoy wild watercress is to include it in salads. Its bold, peppery flavour complements other salad greens and vegetables, creating a refreshing and zesty mix. Pair it with ingredients like cherry tomatoes, cucumbers, radishes, and a light vinaigrette dressing for a delightful salad experience.


Soup and Broth: Wild watercress adds a rich, earthy flavour to soups and broths. It can be used as a primary ingredient or as a garnish. When added to hot liquid, watercress wilts quickly, infusing the dish with its aromatic taste. Consider blending watercress into a creamy potato and watercress soup for a comforting and nourishing treat.


Sandwiches and Wraps: Elevate your sandwiches and wraps by layering them with fresh wild watercress. Its peppery bite provides a contrast to the other ingredients, making each bite more exciting and satisfying.


Stir-Fries: Add wild watercress towards the end of cooking stir-fries to retain its vibrant green colour and fresh flavour. Its peppery notes blend well with various stir-fry ingredients, including mushrooms, bell peppers, tofu, or chicken.


Pesto: For a unique twist on traditional pesto, substitute basil with wild watercress. Watercress pesto delivers a peppery punch and pairs wonderfully with pasta, sandwiches, or as a dip for vegetables.


Omelettes and Frittatas: Enhance the flavour of your omelettes and frittatas by folding in a handful of chopped wild watercress. The gentle cooking process will slightly mellow its spiciness, resulting in a harmonious balance of flavours.


Infused Vinegar: Use wild watercress to create infused vinegar. Steep fresh watercress leaves in white wine vinegar for a few weeks, and you'll have a tangy and slightly peppery vinegar to drizzle over salads or use in dressings.
