Achillea millefolium 'Angie' (Song Siren™) is an upright, compact yarrow with flat flower clusters and finely cut, aromatic foliage. Darwin Perennials' culture guide lists a height of 20–22 inches, a 12–14-inch spread, and flowering from late spring into summer; a regional exact-cultivar listing records bloom from June through September. ## Plant profile The [Royal Horticultural Society](https://www.rhs.org.uk/plants/373755/achillea-millefolium-angie-song-siren-series/details) accepts the cultivar name 'Angie' and places it in the Song Siren Series. The Darwin Perennials guide uses the trade styling Song Siren™ Angie. The exact-cultivar [North Shore Plant Club listing](https://www.northshoreplantclub.com/plant?ID=14117) describes pink flowers, an upright spreading habit, and a 20–22-inch height by 12–16-inch width. Flowering dates vary by region, so the breeder's late-spring/summer timing is a useful general guide and September flowering may occur in some climates. ## Growing conditions The [Darwin Perennials culture guide](https://www.darwinperennials.com/utility/culturesheetpdf.aspx?txtphid=000406782031798) recommends sun. The North Shore listing accepts partial to full sun and gives USDA zones 4a–9b; its 4–9 whole-zone range agrees with the exact-cultivar [plant-library profile](https://www.gardencentermarketing.com/plantname/Achillea-millefolium-Song-Siren-Angie). Use well-drained soil. General [RHS Achillea guidance](https://www.rhs.org.uk/plants/achillea/how-to-grow-achillea) says established plants tolerate dry periods, while young plants need water during dry spells in their first year. Achilleas suit borders, containers, and cut-flower displays. ## Maintenance RHS guidance for Achillea recommends removing spent flowers to encourage further bloom. Flower stems can remain for winter interest and wildlife, then be cut back in early spring; established clumps can be divided every few years if they become congested.
