Yarrow 'Moonshine' is a compact perennial with soft yellow flowers and feathery, fine-textured foliage that holds color throughout the season. It's drought-tolerant, attracts butterflies, and requires minimal maintenance in sunny garden beds.

Why grow it

Achillea 'Moonshine' offers a more compact growth habit and consistent pale yellow flower color compared to taller, more variable yarrow cultivars, making it suitable for smaller garden spaces and mixed borders. Like other yarrows, it tolerates drought and poor soils once established, requires minimal fertilizer or pest management, and provides reliable nectar and pollen sources for beneficial insects. The cultivar's ability to flower from early summer through fall extends the season of appeal relative to many perennial alternatives in the same ecological niche.

Watch out for

Yarrow can self-seed prolifically in ideal conditions, so deadheading spent flowers helps prevent unwanted volunteer seedlings in subsequent seasons. Extended periods of high humidity or poor air circulation may increase susceptibility to powdery mildew, particularly in regions with wet summers. Plants may require division every three to four years as clumps can become woody and less vigorous in the center.
