Heartleaf Arnica (Arnica cordifolia)
This aster has two to four pairs of heart-shaped leaves, topped by one to three broad yellow flower heads. It is sometimes also known as heartleaf leopardbane. It flowers from April to June and sometimes in September and prefers lightly shaded woods.
Did you know? In alpine areas or in open places along roads, the leaves may be narrower and without the notch at the base of the blade. All western species have paired leaves on the stems, but only this one has heart-shaped leaves.
