Coronation Gold (Achillea ageratifolia) is a beautiful tall-growing variety of Yarrow, a perennial herb that lights up my pollinator garden from June through August. I find the metamorphosis of the Coronation Gold flower so fascinating. In the early stages of bloom, the flower head looks like a tiny cauliflower. Over the course of several weeks, the tightly packed flowers gradually open up and flatten out like a small saucer. While the dramatic change in shape is happening, the color of the flower is also transitioning from pale white to a stunning, mustard-yellow color. I wish I had Coronation Gold planted all around my garden, hence the reason why I am harvesting seeds this week.
