About
Arnica latifolia is a species of arnica in the sunflower family, known by the common names broadleaf arnica, broad leaved arnica, mountain arnica, and daffodil leopardbane. It is native to western North America from Alaska east to Northwest Territories and south to Mono County, California, and Taos County, New Mexico. It grows in mountain habitat such as forest and meadows.
Arnica latifolia is a perennial herb growing from a long rhizome and producing a hairy, mostly naked stem 10 to 50 centimeters tall. It has a cluster of leaves around its base and usually a few pairs along the lower part of the stem. The leaves are lance-shaped to broad and nearly heart-shaped, and are usually toothed.
