Blue Beech
Cow Parsnip

Blue Beech is a beautiful, ornamental tree with enticing features. The foliage transforms throughout the season, offering a kaleidoscope of color. New leaves emerge reddish-purple, transforming to dark green, and then turn striking shades of yellow, orange, and red in fall. Once all the foliage has dropped, grooved, blue-grey bark becomes striking on a winter landscape.

Blue Beech has an attractive globular shape and has been successfully grown in both full shade and full sun locations. Make sure you provide ample moisture to ensure this tree thrives.

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.
