Achillea millefolium
Common Yarrow, Mifoil
Description
Common Yarrow is a hardy perennial with hairy, evergreen green foliage. It has a tight cluster of white flowers and typically blooms in the summer months. It attracts bees and butterflies. It prefers full to part sun and becomes drought tolerant once it's established. Following bloom, one should dead head the plant and divide the clumps when it appears crowded to keep it looking tidy.
