Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Edible Uses

Young stems - raw or cooked as a potherb, added to soups etc[5, 13, 52, 62, 183]. The plant is at its best for eating in late summer[264]. The stems are very succulent, but have a thin woody core that is easily removed[264, K]. They are best harvested when about 15cm long, the top 10cm being used leaving the bottom 5cm to produce new shoots[264]. They require little cooking, just adding them to a soup for the last few minutes of cooking is sufficient[9]. The plant has a salty flavour[183] and makes a very pleasant raw nibble[K]. The young shoots can be pickled after first boiling them in their own salted water[183]. Seed[105]. Rich in protein[183]. The seed is rather small and fiddly to utilize[K]. An edible oil is obtained from the seed. A high quality, it is similar to safflower oil (Carthamnus tinctoria)[183].

Special Uses


Cultivation details

Prefers a rich organic soil with ample nitrogen and regular watering[264]. This species is little, if at all, cultivated and its exact requirements are not clearly understood[264]. It is not known if the plant will require periodic inundation by salty water to grow well[264]. Glasswort is difficult to grow in cultivation[52, 264], it can succeed in gardens if sown as soon as the seed is ripe in the autumn in a well-drained soil[52]. A very variable plant both in size and the number of branches produced - a number of subspecies are recognised[264]. The best forms for food production are bushy plants up to 40cm tall with an upright habit that keeps the branches out of the mud[264]. The form sometimes classed as a distinct species (as S. ramosissima Woods.) has this habit and habitat and so is the best form for using in cultivation experiments[264]. When seeking seed for cultivation, try to collect from plants with this habit and also choose plants nearer the high tide mark that therefore receive less inundation[264]. The edible leaves are occasionally sold in local markets[46].

I live near the beach in the southwest corner of Washington State, USA, and a friend introduced me to this plant by bringing me a bunch to eat. I have noticed it growing in the area, and could send to interested parties, with instructions on what/how much is needed, how to pack for shipping, and if you would kindly pay the postage. Are there any restrictions on shipping this stuff off, as in, quarantined from going across borders? Please advise.
