In the United Kingdom, the Keeled-fruited Cornsalad (Valerianella carinata) is a native annual plant species belonging to the Caprifoliaceae family. Also known as Lamb’s Lettuce or Lewiston Cornsalad, it is commonly found in arable fields, grasslands, and disturbed habitats throughout the UK.

Keeled-fruited Cornsalad has modest nutrient requirements, thriving in well-drained soils with moderate fertility. It often grows in open, sunny locations, but can also tolerate partial shade, making it adaptable to a range of environmental conditions.

In its natural habitat, Keeled-fruited Cornsalad serves as a food source for various herbivores, including small mammals and birds, which graze on its tender leaves. However, its low-growing habit and inconspicuous appearance may offer some protection against excessive predation.

As an annual plant, Keeled-fruited Cornsalad completes its life cycle within a single growing season, germinating from seed in the autumn or early spring, flowering and setting seed in the spring or summer, and dying off in the autumn.

Culturally, Keeled-fruited Cornsalad holds limited significance in the UK beyond its role as a common wildflower in agricultural fields and natural habitats. While not widely referenced in literature or folklore, it contributes to the biodiversity and ecological balance of British landscapes.

An interesting fact about Keeled-fruited Cornsalad is its edible leaves, which are often used in salads and culinary dishes as a nutritious and flavourful alternative to traditional lettuce. In some regions, it is also cultivated as a leafy green vegetable for human consumption.
