Number of seeds

Naturally found in several regions of North America, American arnica is a discreet companion in meadows and open clearings. This herbaceous perennial forms small clumps of simple foliage from which, in season, emerge bright yellow flower heads reminiscent of modest sun-kissed daisies. In a harmonious garden, it finds its place in naturalized flowerbeds or quieter spaces, where the aim is to combine native plants with respectful practices.

Without being showy, this plant stands out for its remarkable consistency: a bloom that brightens the beginning of summer and a habit that blends easily into a quiet corner of the garden. Its presence evokes an ancient connection to traditional North American medicinal uses, even if the specific uses may vary depending on the region and related species. Given well-drained soil and gentle cultivation, it contributes to the garden's plant diversity, offering a welcome source of nectar for passing insects.
