The coastal salt marsh grass, Spartina foliosa Trin., was grown in nutrient solution at different salinites (0%—125% sea water; sea water =33%) for 8 weeks. Growth and survival was greatest in fresh water although the plant grows in sea wate in its natural habitat. Protein (17.9% ± 0.8%, dry weight) and lipid (16% ± 0%, dry weight) were higher in fresh water cultured plants than in sea water cultured plants (12.4% ± 0.5% protein, 3% ± 0% lipid). Fresh water plants contained less sodium (0.25%) and more potassium (3.52%) than sea water plants (4.82% sodium, 1.80% potassium).
