Narrow-Leaved Coneflower (Echinacea)

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.

Narrow-Leaved Coneflower is a native perennial wildflower known for its pink to pale purple, daisy-like blooms. The petals (rays) droop downwards, around a dark, domed center, giving the flower a cone-like appearance. The nectar-rich blossoms attract a wide variety of pollinators, including native bees and butterflies. After flowering, the seeds provide food for birds, further adding to its ecological value.

Once established, it is drought-tolerant due to its deep taproot, which also helps stabilize soil. Narrow-Leaved Coneflower thrives in a variety of well-drained soils, including sandy, rocky, and alkaline. It often grows alongside the native grasses that characterize prairie and grassland ecosystems, making it well-suited for prairie and grassland restoration, naturalization, and pollinator gardens.
