About California Bulrush (Schoenoplectus californicus) California Bulrush (Schoenoplectus californicus) is a native perennial herb in the Cyperaceae (Sedge) family that grows in northern, southern and central California. It is also found in Oregon and across the southern states to Florida. It is a definitive species of freshwater or brackish marshes, found in perennially inundated areas such as lakes and ponds, but generally not in flowing water. It tolerates standing water several feet deep where it creates sometimes massive patches. It occurs at elevations from sea level to 4,000 feet, often but not always near the coast. It is an aggressive spreader from its rhizomes and will quickly occupy all suitable area.
