Danish Scurvy-grass
Cochlearia danica
A small, salt-tolerant brassica with fleshy, spoon-shaped leaves and tiny white, four-petalled flowers. It famously colonises roadside verges salted in winter, but on Lihou it takes advantage of natural sea spray. Historically, scurvy-grasses were prized for their high vitamin C content—used to ward off scurvy.
- Habitat: Coastal cliffs, salt-tolerant turf, roadsides (inland).
- When to See: Flowers in spring through early summer.
