Prairie Crocus

Yarrow is a herbaceous, native wildflower that is found across Canada. It features large, flat clusters of tiny white flowers. The blooms attract a variety of pollinators, making it an ideal choice for pollinator gardens. While partial shade is tolerated, the best flowering occurs in full sun. Yarrow is resistant to deer and rabbits, making it both a beautiful and practical addition to your landscape.

The entire plant is edible, but leaves and flowers are most commonly consumed. They have a strong licorice scent and a mild sweet flavor that is similar to tarragon. Yarrow leaves can also be used as a natural insect repellent.

It is important to plant Yarrow in the right place, it can spread quickly via both rhizomes and self-seeding. Deadheading the spent flowers will extend the bloom season and can help limit self-seeding.

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.
