Pickleweed is specially adapted to use saltwater as its main source of water. When the saltwater is taken up, the salt is removed and stored in specialized
vacuoles in the terminal segments. As the vacuoles become full of brine, they turn red and drop off the plant, removing the salt. Although pickleweed can withstand short periods of flooding, it will die under prolonged immersion, as when the estuary mouth closes and the salt marsh floods. Pickleweed is an important nesting habitat for migrating birds. It is also an important food source for the endangered
salt marsh harvest mouse. ==Uses==
