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.

Common Gaillardia is a native perennial wildflower known for its vibrant, daisy-like blooms. Flower petals vary in color from two-tone blooms with an orange-red center and yellow tips to solid yellow. Blooming from early summer to fall, it provides continuous color while attracting bees, butterflies, and other pollinators. The seeds also serve as a food source for birds, adding to its ecological value.

Common Gaillardia is easy to grow and can tolerate heat and drought. If flowering slows in the summer heat, cutting back the plant can encourage a new round of blooms in the fall. It is ideal for pollinator gardens, xeriscaping, naturalization projects, and ornamental plantings.
