  Up to 13cm (5”) across, the flowering, globe-headed ‘His Excellency’ comprise numerous star-shaped, purple-blue flowers borne on sturdy, upright stems. These appear in midsummer and look great in pots, but they can also be woven through a sunny border, dotted in groups among lower-growing perennials that will mask their foliage, which usually dies back before the flowers emerge. Works well when planted in drifts with ornamental grasses and other alliums and makes a wonderful cut flower.
