Common name

Type
Herbaceous perennial
Family
Asteraceae

Arnica montana is a perennial medicinal plant renowned for its vibrant, golden-yellow blooms, resembling a small wild daisy. Its natural habit, erect flower stalks, and slightly downy green foliage give it a rustic charm perfect for herb gardens, rockeries, sunny borders, and alpine-inspired landscapes. Highly prized for its simple, bright appearance, Arnica montana also attracts pollinators and helps create a vibrant, natural, and biodiverse garden.

This perennial prefers a sunny to slightly semi-shaded location, in well-drained, rather light, acidic to neutral, and not overly rich soil. It thrives in cool conditions, poor soils, and locations where water does not stagnate, making it an interesting plant for naturalistic gardens, embankments, dry beds, and well-ventilated areas. Once well established, Arnica montana requires little maintenance, but it appreciates soil that remains slightly moist during periods of intense heat.

Traditionally used as a medicinal plant, Arnica montana is primarily cultivated for its decorative yellow flowers, botanical interest, and hardiness. It adds a beautiful wild touch to perennial beds and pairs very well with grasses, yarrows, bellflowers, daisies, and other meadow plants. Ideal for enriching a medicinal garden, a flowering rockery, or a naturalized landscape, Arnica montana combines bright blooms, a rustic style, and great ecological value.
