What Makes Chamisso Arnica Special?
Chamisso arnica is a herbaceous perennial forb that produces cheerful, bright yellow daisy-like flowers that can brighten up any garden space. As a native species to both Canada and parts of the lower 48 states, this plant has evolved to thrive in North American ecosystems, making it an excellent choice for gardeners committed to supporting local wildlife and reducing maintenance needs.
