One of the most free flowering of all the herbaceous perennials that we grow. Starting in May it will continue right until the first frosts and beyond if given a little protection. Rounded heads of wedgewood blue fluffy flowers are borne high on firm stems. Height 30-45cm (12-18") Needs frost protection or take a few cuttings and overwinter - they're easy!!
