Achillea millefolium, commonly called yarrow, is a perennial that belongs in a beginner's garden by asking very little in return. It belongs to the Asteraceae family, the same broad clan as daisies and sunflowers, and its genus, Achillea, carries a lineage that stretches across meadows on multiple continents. What sets it apart at first glance is its foliage: feathery, finely divided leaves that look almost fern-like and release a sharp, green scent when brushed.
The plant's hardiness range is genuinely remarkable. Rated for Zones 1a through 13b, it covers virtually every climate zone the USDA recognizes in the United States, from the coldest corners of Alaska to the warmth of the tropics. That range is not a typo, yarrow is one of the few perennials that can be planted with confidence almost anywhere in the country. It grows outdoors and, once settled in, asks for only about ten minutes of attention per week, making it one of the most forgiving choices for anyone who is still figuring out their gardening rhythm.
