Achillea millefolium
(Yarrow) is a versatile, hardy perennial in permaculture, acting as a dynamic accumulator, beneficial insect attractor, and living mulch. It thrives in full sun, tolerates drought and poor soil, and spreads via rhizomes to prevent erosion. Its deep roots mine nutrients like potassium and phosphorus, making it ideal for chop-and-drop fertilizer, composting, or companion planting in orchards
