Schoenoplectus tabernaemontani
Soft-stem bulrush
Family: Cyperaceae · Type: perennial · Native
Soft-stem bulrush is a California native perennial found in northwestern California, northern Sierra Nevada, Central Valley, San Francisco Bay Area, southwestern California, and desert regions in fresh marshes, shores, stream bars, and fens at elevations up to 2,400 meters. Flowering in summer, this plant produces small clustered spikelets in panicle-like inflorescences. Growing 0.5 to 2 meters tall with a long rhizome and thick cylindrical stems 2 to 10 millimeters in diameter, it develops 1 to 2 leaf blades that are 1 to 4 millimeters wide and flat toward the tip. Its leaf sheaths split, often leaving behind fibrous remnants, with distinctive perianth bristles surrounding each small fruit. The compact clusters of spikelets and unique stem structure make this bulrush a distinctive wetland plant.
