Common Name: Rock Samphire
Crithmum maritimum is a perennial plant that can grow up to 0.25 metres tall.
It has uses.
Coastal regions of Europe, including Britain, to the Mediterranean and Black Sea.
On cliffs and rocks, or more rarely on shingle or sand, by the sea[
Prefers a moist light sandy or gravelly soil, doing very well between stones or by a south-east facing wall[
]. Requires a warm dry well-drained sunny position and shade from the midday sun[
]. Requires saline conditions[
]. Plants are best grown in moist salty soil or a very well-drained poor dry soil.
When grown away from the coast, this plant requires a warm sheltered position and some protection in cold winters[
At one time this plant was sometimes cultivated in the vegetable garden[
], though it is quite difficult to do this successfully[
]. It is difficult to grow outside its natural habitat[
Seed - best sown as soon as it is ripe in the autumn[
]. Sow in a cold frame and only just cover the seed[
]. Germination usually takes place within 3 - 6 weeks at 15°c[
]. One report says that the seed only has a short viability and should be sown as soon as it is ripe[
], but it has germinated well with us when sown in mid spring in a cold frame[
]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in early summer.
