Scirpus cyperinus (Marsh Bulrush)

Marsh Bulrush, sometimes called "Woolgrass," is not really a grass, even though it looks like one.

Marsh Bulrush is closely related to sedges, plants known for growing in wet areas such as marshes, lake shores, ponds, wet woods and ditches.

Marsh Bulrush grows up to six feet tall. It has leaf blades up to three feet long and nearly an inch wide. Leaf blades have rough edges and fold over at the tip.

Marsh Bulrush is most easily recognized by its flowers and fruits. The flowers are large, reddish-brown and shaggy. They droop in clusters, and each cluster is made of many small spikelets about 1/4 inch long. Plants bloom from June to September. Later, fruits replace the flowers and contain seeds which give it the "wooly" look.

Seeds are eaten by many waterfowl and small mammals, like muskrats.
