Limelight Hydrangea
Fireweed

Limelight Hydrangea is a flowering shrub that is known for its green flowers. As they mature, the flower colour changes from a pale green to a creamy white, followed by shades of pink and red. Hydrangea flowers persist longer compared to other flowering shrubs, blooming from late July into fall. They are a popular choice for flower arrangements.

The Limelight Hydrangea can be grown as a stand alone shrub, as a hedge, or incorporated into a flower garden. Blooms occur on new wood, so regular pruning is encouraged in late winter. This is an award winner from the Proven Winners® collection.

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.
