This plant in my experience does most definitely not require constantly moist soil. It grows in full sun, in sandy poor soil with essentially no care and no irrigation required. Often present in neglected "lawns", cracks in sidewalks, untended commercial landscapes near the shore. Have seen variation in leaf and flower size. Very attractive, delicate, mat forming plant. Could be a useful no care ground cover in difficult areas.

Sea Purslane or Shoreline Seapurslane (Sesuvium portulacastrum) is a superb, mat-forming, creeping seaside plant in coastal areas. It helps stabalize shorelines and dunes and is great and very useful for preventing erosion. It is native to the southeastern coastal U.S. from North Carolina south through Florida, the Keys and throughout much of or all of the Caribbean and Bahamas, west along the Gulf coast into Texas and Mexico. It is also found throughout tropical and subtropical shorelines and coastal areas worldwide. It has thin, short, leathery leaves that are edible and reportedly taste crisp and salty and have useful vitamins and minerals in them. It also has attractive, small, somewhat inconspicuous white to purple or pinkish flowers. A very useful, mat-forming, dune-stabalizing nativ... read more

Prostrate, mat forming, herbaceous perennial with opposite, fleshy, red tinged leaves that can be up to 2 inches long and .5 inches wide. The tiny pinkish purple flowers are solitary in the leaf axils and bloom all year. Its natural habitat is tropical and subtropical coastal shorelines throughout the world. Sea Purslane is an important dune stabalizer on many beaches.
Medicinally this plant has been used to treat scurvy, a vitamin C deficiency and is sold in Asia as a vegetable. In the Caribbean, the leaves are pulverized and used to soothe puncture wounds caused by venomous fish.
