An invaluable foliage plant, 'Powis Castle' is unique in carrying multi-branched stems of silver filigree foliage, which acts as a superb foil to medium-sized flowering perennials such as pinks or scabious. It lacks the distracting yellow flowers of so many of the family which make it necessary to clip or prune them to remove the flowers. Outstanding with pastel colours the dense silver colour is held through the summer but is perhaps at its very best in mid-summer, just right for the bulk of the season's flowers. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
