Snowball Viburnum

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.

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.
