Among the perennials that flower in summer and early fall, yarrow is among the most carefree and heavy blooming. Enjoy the blossoms outdoors in the garden or indoors as cut flowers; you can even dry them for use in winter bouquets.
The large, flat-topped flower clusters rise on 1 1/2- to 3-foot stalks from clumps of lower-growing foliage. Colors range from white to pastel shades to paprika red, but the familiar yellow yarrows are still favorites. Plants grow well in ordinary soil and with only moderate water; in fact, they may languish if soil is too rich or too moist. Divide when clumps get too crowded.
