Why this variety

Coronation Gold is yarrow at its most architectural: tall, upright stems to about 3 feet, fern-like green foliage, and large, flat plates of deep mustard-gold flowers that bloom for months and dry better than almost any other garden flower. It is the yarrow of dried arrangements, cottage borders, and cutting gardens, named for a coronation year and still reigning decades later.

Flat flower plates are a pollinator strategy worth noticing: a flat top is a landing pad, and Coronation Gold’s broad plates host butterflies, bees, and beneficial insects all summer — it is one of the best insectary plants you can grow, feeding the predators that eat your garden pests. The gold color also holds when dried, because the pigments are stable — which is why a bouquet cut in July still looks golden in January.

Florida translation, honestly: Coronation Gold is a North Florida perennial in sharp drainage, not a statewide plant — give it sun, sandy lean soil, and a raised bed, and it will anchor a border for years. Farther south, grow it as a cool-season annual and cut armloads for drying before summer wetness ends the show.

How to grow

Buy transplants or sow seed — Coronation Gold comes fairly true from seed for a named selection, but transplants guarantee the tall, gold form. Plant in full sun and well-drained soil, spacing 24–36 inches apart, in spring. Water in well, then moderate: this is a big plant that wants room and air. Stake only in exposed, windy sites; in lean soil it usually stands on its own.

Water & feeding

Water while establishing, then moderately — drought-tolerant once rooted, and rots in soggy soil. In Florida, a raised bed and watering only when dry are essential. Feed lightly in spring; heavy feeding pushes soft, floppy growth that needs staking and defeats the plant’s sturdy habit.

Common problems

  • Root rot in soggy soil — drainage first.
  • Floppy stems in rich soil or shade — full sun, lean soil, and spacing for airflow.
  • Self-sowing — Coronation Gold seeds freely; deadhead before seed sets if you do not want volunteers, or let a few seed for replacements.
  • Short life in hot, humid summers — North Florida perennial, warmer zones cool-season.

Harvest

Cut flower plates for fresh and dried use when fully open — for drying, hang upside down in a warm, airy spot out of direct sun, and the gold holds for months. Deadhead through summer for rebloom, cut back after the first flush for a second round, and leave fall plates standing for winter structure before cutting back in spring.

Nerdy fact: Coronation Gold’s species, Achillea filipendulina, comes from the mountains of Central Asia, where flat flower plates and fern-like leaves evolved for harsh sun and thin soil — and its genus is named for Achilles, who supposedly used yarrow to staunch his soldiers’ wounds. The plant’s long medicinal history and its pollinator value share a root: yarrow is a chemical factory, and its compounds serve medicine, insects, and gardeners alike.
