Snowball Viburnum

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.

Snowball Viburnum is a popular ornamental shrub with prolific flowering. This plant is prized for its round clusters of white flowers that resemble snowballs, delighting children and adults. In fall, its leaves turn vibrant shades of red.

Snowball Viburnum is sought after as a single accent shrub, but can also make a dense hedge or privacy screen.
