Arnica mollis is a perennial herb producing one or more hairy, glandular, mostly naked stems 20 to 60 centimeters tall. There are 3 to 5 pairs of leaves along mainly the lower half of the stem, each oblong in shape and 4 to 20 centimeters in length.[3]

The inflorescence holds one to a few daisylike flower heads with centers of yellow disc florets and fringes of yellow ray florets. The fruit is an achene with a brownish pappus.[3]

"Mollis" means "soft", referring to the soft hairs on the leaves.[2]: 113
