Plant: Perennial with creeping scaly rhizomes (roots), and numerous
spike like flower clusters. It grows in the mud between low and high
tides and can reach a height of four feet when mature. It tolerates
high salinity by excreting salt through glands on the leaf surfaces. Provides
a good nesting place for the Clapper Rail.
Flowers: On a few short branches with relatively few large, several
to many flowered spikelets. Spikelets are purple to straw colored, 1/8
to 1/4 inch long.
Leaf/Stems: There are hollow tubes in its stems that pass oxygen down
the roots from the leaves. The tops of cordgrass break off in the
fall, providing a rich food source for many marine animals.
