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.

Canada Mint is a native perennial plant known for its fragrant edible leaves. It produces small white to purple flowers in clusters around the stem and is commonly found in wet areas, including ditches and along wetlands, lakes, and rivers. The leaves can be eaten fresh or used to make teas and essential oils.

Canada Mint can spread quickly through underground rhizomes, making it well-suited to naturalization and restoration projects where it can spread freely. In smaller urban yards or gardens, container planting is recommended to help manage its growth. If planted directly in the ground, regular care and maintenance may be needed to limit its spread.
