PhenologyFlowering and fruiting July-October.
IdentificationPerennial 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 CommentsIn many older references this plant went by the name S. virginica, but the type specimen was found to be an annual species. Another synonym is Sarcocornia pacifica. Confusingly, another species -- the former S. europaea -- is now named as S. virginica!

Other Common Name(s)Pickleweed, from the fleshy texture of shoots, which make a tasty, salty snack. Woody Glasswort, Virginia Glasswort
