Scurvy-grass

Scurvy-grass (Cochlearia groenlandica) is a hardy herbaceous perennial belonging to the Brassicaceae family. Recognized for its historical significance in preventing vitamin C deficiency in polar expeditions, it is a specialized crop valued for its nutritional profile and resilience. The plant forms low-growing rosettes of thick, succulent, spoon-shaped leaves.

Originating from the coastal regions of the Arctic and Subarctic, this species is widespread across Greenland, Northern Europe, and North America. It is naturally adapted to harsh environments, thriving in littoral zones and tundra ecosystems. This geographic distribution makes it a unique candidate for cold-climate agriculture.

Botanically, it features a taproot system and a fleshy leaf structure that stores water and nutrients. The plant produces small, white, cross-shaped flowers arranged in racemes. Its physiological traits allow it to tolerate extreme temperature fluctuations and maintain photosynthetic activity during short growing seasons.

Agronomic requirements prioritize moist, well-drained, and nutrient-rich soils. In a farming context, it performs best in cooler climates where high humidity is maintained. Regular irrigation is critical, as the plant is susceptible to desiccation. It prefers partial shade in warmer regions, as excessive heat can lead to early bolting and reduction in leaf quality.

Economic and culinary utility is primarily focused on its fresh leaves, which are rich in ascorbic acid and possess a sharp, horseradish-like flavor. Apart from direct fresh consumption in salads, it is harvested for its potential in functional foods. Common threats include:

• cruciferous flea beetles;
• downy mildew;
• root rot in poorly drained substrates.
