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.

Junegrass is a native, low-growing perennial bunchgrass commonly found in prairies and open woodlands. It is a great choice for prairie restoration and naturalization projects or an attractive accent in ornamental plantings. Spear-shaped seed heads rise above the gray-green lower leaves, maturing to a tan color. Flowering earlier than other upright prairie grasses, it greens up quickly in spring and maintains its appeal well into the fall. It is shorter in stature and rarely forms thick stands, which adds to its understated visual appeal.

Adapted to cooler climates, Junegrass thrives in well-drained, rocky, sandy, or gritty soils and can tolerate drought, cold, and high altitudes. It actively grows in spring and fall when soil temperatures are cool, but in areas that are too hot or humid, it may go dormant by late summer.

As a perennial, it dies back to the crown each winter, it will regrow from the base in the spring. Avoid disturbing the crown during late winter to ensure healthy growth the following season.
