Glaux maritima is a Perennial up to 0.30 metres tall.
It has edible and medicinal uses.
The species is widespread and while it is possibly declining in parts of its range, it is not thought that any global population decline is likely to meet (or be close to meeting) the threshold for Vulnerable. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2013)[
Coasts and inland saline areas in most parts of the northern temperate zone, including Britain.
Grassy salt marshes, crevices of rocks, the foot of cliffs near the sea and saline districts inland; at elevations up to 2,300 metres[
|Conservation Status||Least Concern
Succeeds in most soils. Dislikes shade.
Young shoots - raw or pickled[
Roots - cooked[
]. (This report refers to the sub-species G. maritima obtusifolia[
].) The roots can be harvested at almost any time of the year. The North American Indians would boil them for a long time before eating them. Even so, eating the roots was considered to make one sleepy and eating too many of them could make one nauseous[
Some native North American Indians ate the boiled roots to induce sleep[
Seed - sow spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
If you have sufficient seed it should be worthwhile trying an outdoor sowing in situ in mid spring.
Division in spring. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
