Another edible coastal plant is Sea-blite (Sueda maritima (L.) Dumort.). Sea-blite is a low-growing plant, often forming mats on the shore. Sea-blite can also be found at inland locations, near salt springs.
Sea-blite has thick, linear leaves. The flowers are small and fleshy, and grow in the axils of the stem. At this time of year, Sea-blite is still a small, inconspicuous plant. Later it will grow to between 3 and 5 dm.
The leaves of Sea-blite are very salty, and can be used as a source of salt in soup or stew, or an ingredient in salads. Used as a pot-herb, they should be cooked for 10 to 12 minutes in two to three changes of boiling water, to reduce the salt content.
The most common species in northwestern Europe is Suaeda maritima. It grows along the coasts, especially in saltmarsh areas, and is known in English as common seablite. It is also common along the east coast of North America from Virginia northward. One of its varieties is common in tropical Asia on the land-side edge of mangrove tidal swamps. Another variety of this polymorphic species is common in tidal zones all around Australia (Suaeda maritima var. australis is also classed as Suaeda australis). On the coasts of the Mediterranean Sea a common Suaeda species is Suaeda vera (synon. S. fruticosa). This is known as "shrubby sea-blite" in English, in distinguishment from common sea-blite. It grows taller and forms a bush. In the medieval and early post-medieval centuries it was harvested and burned, and the ashes were processed as a source for sodium carbonate for use in glass-making; see glasswort.
The name Suaeda comes from an Arabic name for the Suaeda vera species and it was assigned as the genus name by the 18th century taxonomist Peter Forsskal during his visit to the Red Sea area in the early 1760s.
