Garden Notes
Yarrow is a tough, aromatic perennial with finely divided, fernlike foliage and broad, flat-topped flower clusters. It handles poor soil, wind, cold, and dry conditions unusually well, making it especially useful in exposed high-altitude gardens. Plants spread by rhizomes and seed, so they may wander beyond their original planting.
Seasonal Record
Record spring emergence, first bloom, peak flowering, pollinator activity, fall color, seed production, and any areas where the plant spreads aggressively.
