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.

Silky Lupine is a native perennial wildflower known for its upright spikes of blue to violet flowers. Blooming from late spring into summer, the nectar-rich, showy blossoms attract a variety of pollinators, especially bees and butterflies. The plant’s fine, silky foliage provides soft texture and visual interest, enhancing landscapes throughout the growing season.

Silky Lupine is a nitrogen-fixing plant that enriches soils and supports surrounding vegetation. Its deep roots stabilize soil, and it spreads naturally by ejecting seeds from drying pods. If spread isn’t desired, new seedlings are easy to remove. While it is foraged by some wild animals, it contains alkaloids that are toxic to livestock. Silky Lupine is well-suited to pollinator gardens, naturalization plantings, erosion control, and ecological restoration projects.
