Dutch Valerian (Valeriana locusta), commonly known as Corn Salad or Lamb's Lettuce, is a cold-hardy, nutrient-dense leafy green belonging to the Valerianaceae family. Known for its rosette of tender, spoon-shaped leaves, Dutch Valerian is prized for its mild, nutty flavor and is a popular addition to salads and gourmet dishes. This versatile and easy-to-grow plant is a favorite among gardeners seeking a cool-season crop.
Dutch Valerian originates from Europe and Western Asia, where it has been cultivated since the Middle Ages. Traditionally foraged from the wild, it became a domesticated crop in the 17th century, particularly in France and the Netherlands. Its tender leaves and adaptability to colder climates made it a staple in European winter gardens, and today it is grown worldwide for both home and commercial use.
Dutch Valerian forms a small rosette of soft, dark green leaves with a smooth texture and slightly nutty flavor. Each plant reaches a height of 10-15 cm (4-6 inches) and has a compact growth habit. The leaves are tender yet sturdy, making them ideal for fresh consumption. The plant thrives in cool weather and is one of the few salad greens that can be harvested during the colder months.
Its mild flavor pairs well with a variety of ingredients, and it is highly regarded for its ability to retain its texture and taste even after harvest. The flowers, small and white or pale blue, appear in the spring if the plant is left to bolt, adding visual appeal and attracting pollinators to the garden.
Sowing: Sow seeds indoors 8–10 weeks before the last frost or directly outdoors in early spring or autumn. Scatter seeds on the soil surface and press lightly without covering, as they need light to germinate. Thin seedlings to 30–45 cm (12–18 inches) apart once established.
Soil: Prefers fertile, well-draining soil with a neutral to slightly acidic pH (6.0–7.0). Enrich the soil with compost or organic matter for healthy growth.
Watering: Water consistently to keep the soil evenly moist but not waterlogged. Dutch Valerian prefers slightly moist conditions, especially during dry periods.
Care: Plant in full sun to partial shade. Mulch around the base to retain moisture and suppress weeds. Remove flower heads if growing for root harvest to direct the plant’s energy toward root development. Divide clumps every 2–3 years to maintain vigor.
Harvesting: Harvest leaves and flowers throughout the growing season for fresh use. Roots are typically harvested in late autumn or early spring of the second year, when their medicinal properties are most potent. Wash and dry roots in a cool, dark place for long-term storage.
Note: Dutch Valerian is a low-maintenance plant that self-seeds readily. It attracts pollinators, making it a beneficial addition to naturalized or pollinator-friendly gardens.
Dutch Valerian is a gourmet green often used in fresh preparations to showcase its delicate flavor and texture.
The tender leaves are most commonly enjoyed raw in salads, where their mild nuttiness pairs beautifully with vinaigrettes, nuts, citrus, and soft cheeses. They can also be lightly sautéed or steamed and used as a side dish or incorporated into soups. Their versatility allows them to complement both savory and sweet dishes, making them a favorite in fine dining.
