Lilac Beauty Yarrow

Achillea millefolium 'Lilac Beauty' forms a mat of finely divided, gray-green foliage with flat clusters of rosy-lilac flowers. The blooms fade toward pink-lilac as they age; the Chicago Botanic Garden reports flowering from early summer into early fall, while RHS describes the flowers as lilac-purple and freely borne. ([Chicago Botanic Garden](https://www.chicagobotanic.org/plant-information/plant-finder/achillea-millefolium-lilac-beauty-common-yarrow), [RHS](https://www.rhs.org.uk/plants/56958/achillea-millefolium-lilac-beauty/details)) ## Garden use Place it in a sunny border, prairie-style planting, or wildlife garden where its low mat and upright flower stems can spread. The Chicago Botanic Garden lists the flowers for cutting and drying and reports visits from bees, butterflies, and hummingbirds; RHS also lists it for cut flowers. ## Growing conditions RHS recommends full sun and moist but well-drained soil, with chalk, loam, or sand listed as suitable. The Chicago Botanic Garden reports deer, rabbit, and drought resistance. The [RHS growing guide](https://www.rhs.org.uk/plants/achillea/how-to-grow-achillea) notes that drought tolerance develops after establishment; water young plants in dry spells. Allow for a mat-forming spread; RHS gives broad mature dimensions of 0.5–1 m, while the Garden describes 24-inch stems. ## Maintenance Cut back untidy foliage in spring. RHS notes that removing flowerheads may encourage another flush during summer; division in spring is an option if the mat needs managing.
