Harebell is a native perennial wildflower known for its bell-shaped, blue-violet flowers. The noddling blooms occur in clusters at the top of slender stems. Blooming in bursts from summer to fall, the flowers attract pollinators such as butterflies, bees, and hummingbirds.

Regular deadheading encourages additional blooms, extending its floral display through the season. Harebell prefers areas with cooler summer climates and does poorly in those that get too hot and humid. It is well suited for native wildflower gardens, pollinator gardens, and naturalization projects.

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.

Bluejoint is a native perennial grass that forms tall, dense colonies. It is one of the most abundant grasses found in Canada and the United States. The extensive shallow root system and spreading rhizomes help stabilise soils, especially in wet meadows, marshes, and along streambanks.
It is a cool-season grass, growing most actively in spring and fall and slowing during the heat of summer. Seeds from its purple-tinged spikes feed birds and small mammals, and the plant itself provides forage for wildlife and livestock, though it does not tolerate heavy grazing. Its tall, dense growth also offers nesting habitat for wetland birds. With these combined values, Bluejoint is well-suited for naturalisation, riparian plantings, and habitat restoration projects.
