Common Yarrow is a perennial, native wildflower that grows up to three feet tall. Its flowers form in tight, flat-topped, white to pink clusters, two to four inches wide, made up of tiny 1/4-inch flower heads, each with four to six petals. The leaves are narrow, feathery and fern-like, about six inches long at the base, becoming progressively smaller toward the top. It grows in dry, sunny areas of deciduous woodlands, fields, and prairies. (July)
