Achillea Borealis

Yarrow Achillea borealis

Achillea borealis (Northern Yarrow) is a hardy, native perennial yarrow found in cooler regions of North America. It is valued for its toughness, adaptability, and naturalistic appearance, making it well suited for native and restoration plantings.

Flat-topped clusters of white to creamy-white flowers bloom in early to mid-summer, rising above finely divided, aromatic green to gray-green foliage. The plant spreads gradually by rhizomes, forming loose colonies over time.

Achillea borealis thrives in full sun and well-drained to dry soils, tolerating poor soils, wind, and drought once established. It is extremely cold hardy, performing reliably in USDA Zones 2–7. The flowers attract pollinators, and the foliage is generally deer resistant.

Mature size:



Height: 12–24 in



Width: 18–30 in (spreading)



Ideal for native plant gardens, meadow plantings, naturalized areas, slopes, and erosion control, Achillea borealis is prized for its durability, ecological value, and low-maintenance growth habit.
