About
Schoenoplectus acutus (syn. Scirpus acutus, Schoenoplectus lacustris, Scirpus lacustris subsp. acutus), called tule , common tule, hardstem tule, tule rush, hardstem bulrush, or viscid bulrush, is a giant species of sedge in the plant family Cyperaceae, native to freshwater marshes all over North America. The common name derives from the Nāhuatl word tōllin [ˈtoːlːin], and it was first recognized by the early Spanish explorers and missionaries in New Spain who saw the marsh plants in the Central Valley of California as similar to those in the marshes around Mexico City being used to construct shelters by the indigenous inhabitants.
Where it grows
It is native to freshwater marshes all over North America. It is especially common in wetlands in California.
Uses
Flour can be made by peeling and cutting up the older roots, crushing and boiling them, removing any fiber, and drying. The seeds can also be ground and mixed with the root flour.
