Foothill arnica (Arnica fulgens) is a cheerful, daisy-like perennial native to western North American grasslands and meadows, producing bright yellow flowers beloved by pollinators. Plant it in well-drained, sandy or loamy soil in a sunny spot and water regularly but avoid soggy conditions; it is well suited to naturalistic and prairie-style gardens. Note that arnica has a long history of topical medicinal use, but all parts are toxic if ingested.
