The inflorescence is a cluster of several daisy-like flower heads with a center of brownish disc florets and a fringe of yellow ray florets 1 to 2 centimeters long. The fruit is a cylindrical achene covered in hairs and with a light brown pappus at one end. It grows in moist areas, along stream banks, and montane to alpine meadows.

Lanceleaf arnica is fairly disease-resistant and usually not prone to illnesses. Still, it can be affected by pests and diseases present in its environment. These issues are typically mild. For care, the plant has moderate maintenance needs. It should be pruned regularly to maintain a neat appearance and encourage healthy growth. Fertilizing can also help stimulate flowering.
