King Edward™ Yarrow

King Edward is a compact, spreading yarrow with woolly, silvery-gray foliage and small pale primrose-yellow flower heads. The Royal Horticultural Society accepts the name [Achillea × lewisii 'King Edward'](https://www.rhs.org.uk/plants/94981/achillea-%C3%97-lewisii-king-edward/details), and [Darwin Perennials](https://www.darwinperennials.com/Products/Details/?phid=000400822002757) lists a 6–10 inch height and spread. ## Landscape Use Use this small yarrow in rock gardens, path edges, containers, or as a low accent near walks. Its pale flowers sit above a close mat of textured foliage. The [RHS](https://www.rhs.org.uk/plants/94981/achillea-%C3%97-lewisii-king-edward/details) describes its habit as spreading and gives a maximum height of 10 cm; [Darwin Perennials](https://www.darwinperennials.com/Products/Details/?phid=000400822002757) calls its habit upright and reports 6–10 inches for both height and spread. Both recommend full sun. Plant size and form vary between these references. ## Seasonal Interest Flowers are reported from late spring into early summer. Silvery leaves often remain through winter, though persistence depends on climate. The [RHS](https://www.rhs.org.uk/plants/94981/achillea-%C3%97-lewisii-king-edward/details) describes the foliage as semi-evergreen. ## Maintenance Choose a sunny site with drainage. Cut back untidy foliage in spring and remove faded flower stems when the display ends.
