Yarrow is an easy perennial, growing in nearly any sunny situation, even where there is poor soil. This species forms a tall, bushy mound of fragrant ferny foliage, with huge clusters of golden-yellow flowers appearing on tall stems beginning in early summer. Outstanding for cutting, fresh or dried. Remove faded flowers regularly to promote continued blooming. Not a spreading species, this has a strongly clumping habit. Staking is usually necessary, particularly if grown in rich garden soil. Easily divided in fall or early spring. Heat tolerant.
