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.

Nodding Onion is a native perennial wildflower known for its nodding clusters of flowers that range in color from white to pink to purple. The lightly scented blooms provide pollen and nectar for pollinators, especially bees, which can collect while hanging upside down, a capability most other insects lack.

The narrow, grass-like leaves of the Nodding Onion can be used as a seasoning in cooked dishes, though bulbs and raw leaves should not be eaten in large quantities. All parts of the plant have an onion-like aroma when bruised, which helps deter deer and rabbits. They can self-seed readily, so removing spent blooms helps manage their spread. Tolerant of a range of soils, including alkaline, it is well-suited for a variety of plantings, including pollinator gardens and naturalization projects.
