Yarrow
Slough Grass

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.

Slough Grass is a hardy grass that will happily grow in any wet soil. It is usually found near water and is common haymaking material or forage.

Slough Grass is also useful for erosion control and land reclamation.
