Harebell vs Cow Parsnip

Cow Parsnip is a native perennial wildflower known for its tall growth, very large leaves, and broad clusters of white flowers. The abundant blossoms provide nectar and pollen for a wide variety of pollinators, including bees and butterflies. Birds and small mammals feed on its seeds, while the foliage serves as a larval host for certain butterfly species.

Cow Parsnip is often among the first native perennials to establish in disturbed or open sites. It typically grows in moist meadows, along streambanks, forest edges, and roadsides. Although usually a short-lived perennial or biennial, it readily self-seeds and maintains strong populations where conditions are favorable.

Cow Parsnip is the only native Heracleum in North America and should not be confused with the highly invasive Giant Hogweed (H. mantegazzianum).

Note: The sap of the Cow Parsnip can cause phytodermatitis when exposed to ultraviolet light (sunlight). This can cause rashes or even burns. Care should be taken if pruning or handling this plant.

Harebell is a native perennial wildflower known for its bell-shaped, blue-violet flowers. The noddling blooms occur in clusters at the top of slender stems. Blooming in bursts from summer to fall, the flowers attract pollinators such as butterflies, bees, and hummingbirds.

Regular deadheading encourages additional blooms, extending its floral display through the season. Harebell prefers areas with cooler summer climates and does poorly in those that get too hot and humid. It is well suited for native wildflower gardens, pollinator gardens, and naturalization projects.
