About
Salicornia is a genus of succulent, halophytic (salt tolerant) flowering plants in the family Amaranthaceae that grow in salt marshes, on beaches, and among mangroves. Salicornia species are native to North America, Europe, central Asia, and southern Africa. Common names for the genus include glasswort, pickleweed, picklegrass, and marsh samphire; these common names are also used for some species not in Salicornia. To French speakers in Atlantic Canada, they are known colloquially as tétines de souris ('mouse tits'). The main European species is often eaten, called marsh samphire in Britain, and the main North American species is occasionally sold in grocery stores or appears on restaurant menus as sea beans, samphire greens, or sea asparagus.
Where it grows
The species of Salicornia are widely distributed over the Northern Hemisphere and in southern Africa, ranging from the subtropics to subarctic regions. There is one species present in New Zealand.
