About

Common glasswort, also known as 'Marsh samphire', grows in saltmarshes, and around beaches and coastal places across the UK. But it is in East Anglia where it is most well-known as a wild food - gathered and displayed alongside fish. Its succulent nature is what makes it so attractive to eat, but also makes it tolerant to the harsh conditions of the shore. Its flowers appear from August to September.

How to identify

Common glasswort can easily be confused with other glasswort plants (there are seven in total). Look for a yellowy-green, fleshy plant, a little like a cactus. The stems are roundish and snap easily, and the tiny, thin flowers point upwards.

Distribution

Found scattered around the UK's coasts.

Did you know?

The ashes of vommon glasswort were traditionally used to make glass and soap, hence the common name. This is because of the high salt concentration within the plant which stops it from losing water to the environment and enables it to live in such salty conditions.
