Aquatic Pygmyweed
Crassula aquatica (L.) Schönland
Crassula aquatica, commonly known as Aquatic Pygmyweed, is a succulent annual plant found in wetland habitats such as salt marshes, vernal pools, and brackish water bodies. It is partially aquatic and thrives in areas that are often submerged, as well as along muddy banks and in estuaries with tidal activity. The species is native to regions in North America and parts of Europe, including Newfoundland, British Columbia, Portugal, and others.
Description
Crassula aquatica is a member of the Crassulaceae family and is adapted to moist or aquatic environments. It grows in fresh to brackish water settings, including wetlands and estuaries, where it can tolerate submersion for extended periods.
