UMBRELLA SEDGE

The umbrella sedge, with its long, narrow, green leaves that splay into a whorl is a typical member of the sedge family.

This type of sedge is a wetland herb that flourishes in rich, moist soil near streams and along river banks in Southern California. The grass-like plant grows in coarse tufts.

The umbrella sedge ( Cyperus alternifolius) reaches heights of up to 6 feet.

It is so named because of its shape.

In the late summer, its triangular, solid stems are topped by dry, greenish-brown clusters of compact flower heads.

A native of Madagascar, the umbrella sedge was introduced to Europe around 1780. Soon after, it made its way across the ocean to the United States.

Botanists know of about 90 genera and 4,000 species of the sedge family throughout the world. Bulrush, cotton grass and tule are members of this family.

Anywhere they grow, sedges usually inhabit wet marshes and the edges of streams and ponds. Their roots often are partially submerged in water.

A few species, including the umbrella sedge, are grown as decorative plants.

Others are used as sand or soil binders. Pictured here are umbrella sedge plants growing along the Santa Clara River in the Santa Clarita Valley.
