Western Goldenrod

Euthamia occidentalis

Also known as Western Flat Topped Goldenrod, Western Goldentop, Western Flat-topped Goldenrod

Western goldenrod thrives in soggy soils along riverbanks, irrigation ditches, and marsh borders throughout western North America. Unlike upright plume-forming goldenrods, it bears its bright yellow flower heads in broad, flat-topped clusters atop slender stems lined with narrow, resin-scented leaves. It forms extensive clonal colonies via creeping rhizomes, providing vital nectar for migrating monarchs and nesting cover for wetland wildlife late into the autumn.
