Chives are small bulbous perennials commonly used as herbs in cooking for a mild onion like flavour. Chives also add ornamental benefits to your yard with their tubular grass-like leaves and clusters of pale purple flowers. The flower heads can also be used as a garnish or in oils.

It is best to harvest Chives from the base to maintain the attractive clumps. If the flowers are not dead-headed, it will self-seed. Planting our overwintered chives will give you a head start in your vegetable garden.

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.
