Yarrow (Common)

📖 About This Plant

Yarrow (Common / Achillea millefolium) is a drought-resistant North American native wildflower and medicinal herb that produces flat-topped clusters of tiny flowers above ferny, aromatic foliage from early summer through fall. Hardy in zones 3–9, it grows 2–3 feet tall in a natural range of white and soft pink, with cultivated varieties extending the color palette to red, yellow, orange, and deep burgundy. Yarrow is a powerhouse companion plant — its flat flowers are a critical nectar source for parasitic wasps and hoverflies that control garden pests, and its deep roots mine minerals that enrich the soil. It's virtually indestructible once established: drought-tolerant, deer-resistant, spreads steadily, and thrives in conditions where most plants struggle.

🌱 Care Tips

Direct sow yarrow in early spring or fall on the soil surface — seeds need light to germinate. Or divide established clumps in spring. Plant in full sun in well-drained to dry soil. Yarrow is notably drought-tolerant once established and actually performs better in lean, unirrigated soil — rich, moist beds cause floppy, weak-stemmed growth. Do not fertilize. Water sparingly. Deadhead spent flower clusters to extend blooming and prevent unwanted self-seeding, or leave seed heads for birds. Divide crowded clumps every 3 years to maintain vigor; yarrow can spread aggressively in ideal conditions. Excellent cut flower — harvest when 2/3 of florets in the cluster are open; air-dry upright for everlasting dried arrangements that hold color for months. Plant yarrow throughout the vegetable garden as a companion to attract beneficial predatory insects.
