Cow Parsnip
Early Blue Violet

Cow Parsnip is a native perennial plant that grows tall with very large leaves and broad clusters of white flowers. It grows quickly, providing quick cover in disturbed areas.
Its flowers are large and plentiful, providing nectar and pollen for bees, flies, and butterflies. Its seeds are eaten by birds and small mammals. The young shoots of the plant are edible, but care must be taken as the sap of this plant can cause skin irritation (see below).
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.

Early Blue Violet is a low-growing native perennial wildflower valued for its striking early-spring blooms. The flowers range in color from vibrant blue to deep violet, often marked with pale highlights and fine white hairs. They provide an important early nectar source for pollinators and serve as a host plant for several fritillary butterfly species.

It spreads by both seed and rhizomes, gradually forming small colonies. Its dark green, heart-shaped leaves add ornamental appeal, and the plant shows some resistance to deer browsing. Early Blue Violet is well-suited to naturalization projects and pollinator-friendly gardens, and has also been used in coastal butterfly habitat restoration in the Pacific Northwest.
