Prairie Crocus

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.

Prairie Crocus is a native perennial wildflower that is often considered one of the first signs of spring. The flowers can range from purple, pale blue, to white and often appear before the snow has fully melted. It can bloom a month earlier than other spring flowers, providing an early source of pollen for a variety of pollinators.

The plant is covered in woolly white hairs, including the finely divided leaves, giving them a silvery appearance. Prairie Crocus leaves do not fully emerge until after it has bloomed. The spent blooms transform into fluffy, feathery seed heads. During the hot summer months, the Prairie Crocus goes dormant and will repeat its life cycle the following spring.

The Prairie Crocus is Manitoba’s provincial flower.

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.
