Wood Lily
Cow Parsnip

Wood Lily is a native perennial wildflower known for its vibrant, trumpet-shaped blooms in shades of orange to red. Its showy flowers appear mid-summer and are highly visible in meadows and prairies. The upward-facing flowers are an important nectar source for many pollinators, including native bees, butterflies, and hummingbirds.
Unlike most lilies, the Wood Lily’s flowers face upward rather than nodding. It is slow to establish and may take years before flowering, but once mature, it requires little maintenance. It is well-suited for pollinator gardens, naturalisation projects, prairie restoration, and open woodland plantings.
Wood Lily is the provincial flower of Saskatchewan and North America’s most widespread lily. Despite its wide natural range, populations have been declining. Habitat loss, overgrazing by deer, and unsustainable picking have reduced both its abundance and density across many regions. These pressures highlight the importance of protecting and restoring this once-common wildflower.

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.
