Achilleas are traditional border flowers valued for their feathery foliage and striking flat, circular heads of flowers throughout the main summer season. They team well with other perennial flowers and are a vital ingredient of a traditional herbaceous border. They are also at home in island beds, cottage gardens and other perennial planting schemes. The variety 'Coronation Gold' has silvery foliage and flowers of gleaming golden yellow that are attractive to bees. The blooms also are good for cutting or drying. Plants spread slowly into fat clumps without becoming invasive. It has been given an Award of Garden Merit (AGM), which is for plants of outstanding excellence.
