Smooth cordgrass is a native perennial grass with flat, blade-like leaves. It grows in low-lying, salt and brackish tidal marshes along the shores of the middle and lower Chesapeake Bay.
Smooth cordgrass has smooth, blade-like leaves that taper to a point. The leaves leaves grow 12 to 20 inches in length and one-half an inch wide. Tiny, white flowers bloom in July to September. It has round, hollow stems and a strong, interconnected root system. Smooth cordgrass grows in two forms: a short form that grows to 2 feet tall, and a tall form that can reach 7 feet tall.
This plant grows between the low- and high-tide marks in salt and brackish marshes, forming dense colonies that usually parallel the shoreline. The short form more common in slightly higher areas, while the tall form is more common in low areas that are flooded by tides every day.
Found along the shores of the middle and lower Chesapeake Bay and its tidal creeks and rivers.
Smooth cordgrass usually reproduces asexually when its long, underground rhizomes spread and form new stems. Flowers mature into foot-long seed spikes in autumn.
