Bluejoint vs Blue Grama Grass

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.

Blue Grama is a native perennial bunchgrass recognized for its blue-green blades and unique seed heads. They grow along one side of the stem and are often compared to eyelashes, eyebrows, or mosquito larvae, which inspired its common names, Eyelash Grass and Mosquito Grass. As the seed heads begin to dry in the fall, they curl, further enhancing the plant’s distinctive appearance. The seeds provide food for birds, and the grass serves as a host plant for certain species of skipper butterflies.

As a warm-season grass, Blue Grama has a slow start in spring and does not actively grow until soil temperatures rise. Its deep roots help with erosion control, and the grass is drought-tolerant once established, thriving even in poor or alkaline soils. It is well-suited for soil stabilization, naturalization, restoration projects, or as an ornamental accent in gardens and landscapes.
