Purple Prairie Clover

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.

Purple Prairie Clover is a native perennial wildflower known for its striking purple blooms. The flower heads grow as dense spikes on tall stems, with each flower head containing many tiny blossoms. Blooming for 4–6 weeks in the summer, it attracts a variety of pollinators, including bees and butterflies.

The high protein content of the Purple Prairie Clover makes it excellent forage for wildlife and birds like to feed on its seeds. As a nitrogen-fixing plant, it enriches the soil, improving fertility and benefiting nearby vegetation. These ecological contributions make it a great choice for pollinator gardens, prairie & rangeland restoration, naturalization, and re-vegetation efforts.

This drought and heat-tolerant plant thrives in various soil conditions, including rocky soil, making it remarkably easy to grow in challenging environments. 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.
