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.

Missouri Goldenrod is a native perennial wildflower known for its brilliant golden yellow flowers that bloom from late summer to early fall. The flower heads contain hundreds of tiny blossoms that attract a wide variety of pollinators, including bees, butterflies, and other beneficial insects. Fully opened flowers can also be used to make tea. As the season progresses, the flowers give way to fluffy seed heads, providing food for birds.

It can spread readily through its roots and self-seeding, this make Missouri Goldenrod well suited for hard-to-grow areas. This vigorous growth habit makes it an excellent choice for large planting areas, wildflower gardens, naturalized projects, prairie restoration, and erosion control.
