Dwarf Saltbush, Baccharis dioca,

the mature height of this fast-growing, medium-bushy accent shrub is 6′ or less, so does well as buffer plantings. It likes full sun, and moist, well-drained soil as well as moderate amounts of salt wind. But, it does not tolerate salty floods or brackish water. Once established, it is drought tolerant. Its fragrant, semi-showy white flowers bloom in the fall. Fruit masses, which can also be showy, provide food and cover for wildlife.
