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.

The Eastern Redbud is known for the pea-like pink buds that emerge in clusters on the bark, embellishing the tree in stunning flowers. They have a longer bloom time, sometimes for two to three weeks before the heart-shaped leaves emerge for the summer. Inedible pods emerge that turn brown in the summer, this tree is a part of the bean family.

Native to the Eastern North America. The Eastern Redbud can tolerate acidic and alkaline soil. Plant this as a beautiful understory species or shaded residential yard or garden. The bright pop of color will make an attractive ornamental tree.
