Plant Achillea millefolium 'Pink Grapefruit' (Yarrow 'Pink Grapefruit') where you want bold summer color and a sturdy, easy perennial. You get flattened clusters of deep rose blooms that soften to pink, held above finely cut, aromatic foliage that adds texture even when the plant is not in flower.
Give it full sun for the best flowering, but it will also handle part shade, especially where afternoons are hot. This yarrow is happiest in lean to average soil with excellent drainage; avoid constantly wet, rich soil that can lead to weak stems and flopping.
At maturity, expect a clump about 24-30 inches tall with a roughly 24-30 inch spread. Use it in pollinator beds, cottage-style plantings, and sunny naturalized areas, and enjoy the way it draws butterflies and other beneficial insects through the season.
For the tidiest look and more bloom, shear stems after the first flush to encourage fresh growth and additional flowers. Divide clumps every few years if needed, and remove spent flower heads if you want to limit self-sowing and keep the planting neat.
