Schoeneoplectus californicus is a species of sedge known by the common names California bulrush, southern bulrush and giant bulrush. It is also sometimes called "tule", but the closely related Schoenoplectus acutus is the species most often referred to by that name.
Schoenoplectus californicus is a rhizomed water plant found in marshy areas. It is native to the southern and western United States as well as Mexico, Central America, South America, Easter Island, and the Falkland Islands. It is naturalized on some Pacific islands including New Zealand, Hawaii and the Cook Islands.  It has tall, thin, dark green stems which are usually triangular in cross-section and woolly, bristly tan or brown flowers in panicle inflorescences.
A notable subspecies is the Totora, Schoenoplectus californicus ssp. tatora. This is famous for making up the floating islands on which the Uros people of Lake Titicaca dwell, as well as occurring on isolated Easter Island in the Pacific.
