Heart-leaf arnica is a low-growing native wildflower that produces bright yellow daisy-like blooms from May through July. This woodland perennial spreads gradually by underground rhizomes and goes dormant in winter, disappearing completely until spring growth returns.
In an HOA neighborhood
Heart-leaf Arnica takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
- Completely disappears in winter leaving bare ground

Wildlife value
The cheerful yellow flowers attract bees, butterflies, and beetles during the late spring and early summer blooming period. As a native plant, it provides important nectar resources for local pollinators.
Native range data from the USDA PLANTS Database and regional native plant society lists. Pollinator and host plant associations compiled from GBIF, iNaturalist, and published ecological literature.
