Tules - The Oregon Encyclopedia
In Oregon and much of the western United States, tule is the common name for two species of emergent plants that grow in shallow water of marshes, muddy shores, and lakes. These sedges (family Cyperaceae) are named hard-stemmed ( Schoenoplectus acutus var. occidentalis) and soft-stemmed ( S. tabernaemontani) bulrushes.
