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.

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.
