It can easily be seen in the lowest and top-most leaves, that which is red, that the leaves are not as thick as they look, but are rather strongly revolute (in-rolled). The leaves are 3-7mm long and toothless (entire).

Stems have very short stubble hairs.


The leaves could be mistaken for those of : Hottentot-Fig but they are much shorter and not solid but in-rolled.

Uniquely identifiable characteristics

Distinguishing Feature :

It is native and only grows near the sea.

The leaves are semi-succulent and are not as thick as what may first appear: for the edges are strongly in-rolled, like those of Bog Rosemary. It is the only plant in the Frankenia genus (at least in the UK). Sea Heath is quite rare and occurs only along some coasts near the sea on sandy or silty bareish ground or on the drier parts of saltmarshes. It occurs in the Channel Islands and in South East England, North Lincolnshire, and on Anglesey.
