Arnica ovata is a mountain wildflower native to western North America, producing cheerful yellow daisy-like blooms in summer. It prefers cool, well-draining soils and thrives in rock gardens or naturalistic alpine plantings with moderate moisture. Arnica species have a long history of medicinal use and are best kept in outdoor naturalistic settings rather than indoors.
