The delicate primrose-yellow blooms of Anthea yarrow (Achillea 'Anblo') sit as flat clusters atop upright stems held well above its dense, fern-like foliage. Easy to grow in a variety of well-drained soils ranging from clay to loam to sand, yarrow creates vibrant contrast when grown with rich purple flowers such as sage or Siberian iris. Anthea yarrow is the perfect plant for the suburban border garden. It is naturally deer and rabbit resistant and is tolerant of drought and salt. A butterfly attractant, it is lightly fragrant, and deadheading produces lovely dried flowers as well as encourages a second bloom.
