Edible Uses
Edible Parts: Leaves;  Seedpod.
Edible Uses:

Leaves - raw or cooked[2, 4, 5, 7, 12, 27, 37]. Vaguely reminiscent of fennel, but the taste is more bitter and brackish[132]. A powerful salty flavour, it has been described by one person as tasting like 'a mixture of celery and kerosene'[238]. The leaves are used as a flavouring in salads etc[132]. Gathered in spring, the young leaves when sprinkled with salt and boiled make a very good pickle[4]. The leaves are rich in vitamin C[238]. Seed pods[4, 5, 7, 12]. They are used to make a warm aromatic pickle[2].

Carminative;  Depurative;  Digestive;  Diuretic.

Rock samphire is little used in herbal medicine, though it is a good diuretic and holds out potential as a treatment for obesity[254]. It has a high vitamin C and mineral content and is thought to relieve flatulence and to act as a digestive remedy[254]. The young growing tips are carminative, depurative, digestive and diuretic[7, 238]. They are gathered when in active growth in the spring and used fresh[7, 238]. The leaves have the reputation for helping people lose weight and so are used in treating cases of obesity as well kidney complaints and sluggishness[238]. The essential oil is a digestive, a few drops being sprinkled on the food[7].
Other Uses

An essential oil from the plant is used in perfumery[7].
Cultivation details
Prefers a moist light sandy or gravelly soil, doing very well between stones or by a south-east facing wall[37]. Requires a warm dry well-drained sunny position and shade from the midday sun[1, 200]. Requires saline conditions[200]. 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[238]. At one time this plant was sometimes cultivated in the vegetable garden[2], though it is quite difficult to do this successfully[1, 37]. It is difficult to grow outside its natural habitat[164].
Seed - best sown as soon as it is ripe in the autumn[1]. Sow in a cold frame and only just cover the seed[164]. Germination usually takes place within 3 - 6 weeks at 15°c[164]. One report says that the seed only has a short viability and should be sown as soon as it is ripe[238], but it has germinated well with us when sown in April in a cold frame[K]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in early summer. Division in spring[238].

I grow it in the Herb Garden at The Huntington Library and Botanical Gardens and I find that once it gets going it will spread and if you pull it out on an area it may come back from the roots. I don't have salty soil so it does not taste salty, so when I tried to pickle it using 15th century resipe, it didnn't taste so good till I added more salt. Thank you for the wonderful website, I use if all the time for my herbal studies.
