Prairie Crocus

Pennsylvania Cinquefoil is well suited for naturalisation projects as it is a wildflower native to North America. It is widespread and can be found growing in rocky soils at higher elevations in the mountains and foothills, as well as the dry prairies. The Pennsylvania Cinquefoil is capable of growing in cold, harsh conditions. The bright yellow flowers are found at the top of long stalks in small dense clusters and are ideal for attracting pollinators.

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.
