Arnica, Heartleaf (Arnica cordifolia)

Heartleaf Arnica is an endearing perennial wildflower native to the forests, meadows, and mountain slopes of western North America. True to its name, it bears heart-shaped basal leaves that gather in low, green rosettes before sending up slender stems topped with bright yellow, daisy-like blossoms. The nectar and pollen of these cheerful flowers draw native bees, butterflies, and other forest-dwelling pollinators, making Heartleaf Arnica an important contributor in mountain and foothill ecosystems.

Like other members of the Arnica genus, this species has a long history of use among early herbal practitioners, primarily for external applications. Infused oils, poultices, and compresses made from the flowers were used to support physical comfort after exertion, such as soothing tired muscles or bruises. Modern herbalism continues to value arnica for topical use, while internal consumption is avoided due to potent compounds, a reminder of its strength and the respect it commands.

In naturalized or shade-adapted garden spaces, Heartleaf Arnica is prized for its resilience and woodland beauty. It thrives in dappled light and cool, undisturbed soils, forming slowly spreading colonies of soft foliage punctuated by bright golden blooms. Its gentle appearance contrasts with its rugged alpine heritage, bringing a sense of mountain calm to cultivated landscapes.
