Tall Manna Grass
Yarrow

Manna Grass and other waterside plants are an excellent way to prevent erosion and provide habitat and forage for animals. The difference is that Manna Grass looks better doing it! With distinctive purple grains at the top of its stalks, Manna Grass adds a splash of color to the waterside that most other aquatics can't offer.

Manna Grass is good for returning disturbed sites to nature and provides nourishment to many animals, except for cattle who find it toxic.

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.
