Description

From the Ladybird Johnson Wildflower Center website: Yarrow grows to 3 feet tall and has no branches except near the top. The leaves are alternate, 3-5 inches long, with many leaflets on each side of the midrib (1- pinnately lobed); and these are further divided into smaller leaflets, giving them a delicate, fernlike, lacy appearance. Flower heads are arranged in large, compact clusters at the top of the stem, each cluster consisting of 1 or more flower heads. The flower head has 20-25 yellowish-white ray flowers and similarly colored disk flowers.
