Spartina alternifolia - Saltmarsh cordgrass is dominant grass in coastal plains of eastern North America, growing 3 to 8 feet tall in moist, sandy coastal regions. Its leaves are green with silvery-white undersides. Flowers appear late summer through fall, with seeds ripening soon after. It's a great plant for wildlife gardens in coastal areas but needs lots of room, as it tends to form thick mats over time. Works well when combined with fall-blooming perennials like goldenrod and gayfeather.
