Rock Samphire
Crithmum maritimum
This aromatic, fleshy-leaved plant grows in rocky crevices and cliff faces by the sea. Historically prized for pickling (sometimes called “sea fennel”), Rock Samphire has a zesty, salty flavour. On Lihou, it can sprout from cracks in the coastal rocks, its umbrella-like clusters of yellowish flowers appearing in summer.
- Habitat: Rocky cliffs, coastal rock crevices, shingle banks—particularly salt-sprayed sites.
- When to See: Flowers from mid- to late summer; leaves visible most of the year.
- Length: Generally 10–30 cm tall (can sprawl further in cracks).
