Among the most carefree and generously blooming perennials for summer and early fall, several being equally useful in the garden and as cut flowers (taller kinds may be cut and dried for winter bouquets). Leaves are gray or green, bitter-aromatic, usually finely divided (some with toothed edges). Flower heads are usually in flattish clusters. Yarrows need only routine care: some watering (though they endure drought once established), cutting back after bloom, dividing when clumps get crowded.Achillea filipendulina
Tall, erect plants 4-5 ft. high and to 3 ft. wide, with deep green, fernlike leaves. Bright yellow flower heads in large, flat-topped clusters. Dried or fresh, they are good for flower arrangements.
Native to Europe and western Asia. Erect plant with narrow green or grayish-green leaves and flat-topped white flower clusters on 3-ft. stems. Spreads by underground runners. Many garden varieties have been selected for their flower color, which includes shades of cream to yellow, pink, and red.Achillea tomentosa
From Europe, western Asia. Makes a flat, spreading mat (about 1 1/2 ft. wide) of fernlike, hairy leaves. Golden flower heads in flat clusters top 6-10-in. stems. A good edging and a neat ground cover for small areas; useful in rock gardens. Shear off dead flowers to leave attractive gray-green mat.Achillea x taygetea
Native to eastern Mediterranean. Grows 1 1/2 ft. high and wide, with gray-green, divided leaves 3–4 in. long. Dense clusters of bright yellow flower heads fade to primrose yellow—excellent contrast in yellow until it’s time to shear off old stalks. Good cut flowers.
