Wood Lily
Nodding Onion

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.

Nodding Onion is a native perennial wildflower known for its nodding clusters of flowers that range in color from white to pink to purple. The lightly scented blooms provide pollen and nectar for pollinators, especially bees, which can collect while hanging upside down, a capability most other insects lack.

The narrow, grass-like leaves of the Nodding Onion can be used as a seasoning in cooked dishes, though bulbs and raw leaves should not be eaten in large quantities. All parts of the plant have an onion-like aroma when bruised, which helps deter deer and rabbits. They can self-seed readily, so removing spent blooms helps manage their spread. Tolerant of a range of soils, including alkaline, it is well-suited for a variety of plantings, including pollinator gardens and naturalization projects.
