western goldenrod
Euthamia occidentalisAlso known as Western Flat Topped Goldenrod, Western Goldentop
Western goldenrod thrives in damp, sunny environments across western North America, forming dense colonies along riverbanks and marsh edges. Its slender, grass-like leaves and flat-topped clusters of tiny yellow flowers provide a vital late-season nectar source for migrating butterflies and native bees. This hardy perennial spreads via underground rhizomes, helping to stabilize soil in fragile riparian ecosystems.
