| Identification | Perennial Glasswort is told from our other two glassworts by its perennial habit with tough, surficial, horizontal to ascending stems extending up to 2 feet long. Vertical shoots rise up to 7 inches, branched or not, fleshy textured, and many-jointed. Tiny flowers occur at the joints of terminal spikes. This species can often form mats, unlike the other two glasswort species; they also lack the perennial stem, the shoots are shorter and fleshier, and typically have more branches. | |
| Taxonomic Comments | In many older references this perennial plant went by the name S. virginica, but the type specimen was found to be an annual species (the former S. eurpoaea). Other synonyms are Sarcocornia ambigua and Sarcocornia pacifica. The former S. europaea is now named as S. virginica.
