Cow Parsnip vs Blue Flax

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.

Blue Flax is a native perennial wildflower known for its blue to violet flowers. Each flower lasts just a single day, but new blooms appear continuously, providing weeks of colour. This extended flowering period provides a reliable display from late spring into summer and attracts a variety of pollinators.

They can self-seed readily, so removing spent blooms helps manage their spread. Birds feed on the seeds, and when cooked, they are edible and are described as having a mild, nutty flavour. The plant grows in loose clumps with slender stems and fine foliage. Young plants are leafy, but as they mature, most leaves are shed.

Blue Flax grows well in a wide range of soils, including poor or sandy conditions, and is drought-tolerant once established. The deep root system helps to stabilize soil and prevent erosion. They are well-suited for pollinator gardens, restoration, naturalization, and xeriscaping projects.
