Yarrow produces an abundance of broad, flat-topped flower clusters (or corymbs) made up of dozens of tiny daisy-like florets. Colors range from white and soft pastels to brilliant shades of yellow, red, orange and gold. Some cultivars, such as ‘Red Velvet’, have flowers with contrasting center stamens. The feathery foliage is also attractive, with finely divided gray or green leaves that remain evergreen in warmer climates.
