Nodding Onion
Fireweed

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.

Fireweed is a native perennial wildflower known for its tall spikes of bright pink to purple blooms. Its long-lasting summer flowers are an important nectar source for pollinators such as bees, butterflies, and hummingbirds, while its seeds provide food for birds. Its showy, long-lasting display makes it visually striking in naturalized plantings.

Fireweed gets its namesake because it is often one of the first species to return after wildfires, supporting ecosystem recovery. Its wind-dispersed seeds allow it to spread readily, making it highly effective in large-scale restoration, revegetation, and naturalization projects.
Fireweed is the Provincial Flower of the Yukon.
