Standing regally on straight stems, the lilac-purple spheres of Allium 'His Excellency' will be a real crowd-pleaser in your garden, ushering it from late spring into early summer with plenty of grace and style. Each flowerhead is a perfect globe and, sitting at a statuesque height of around 1m, they will be sure to create an unmissable display. Those tight clusters of star-shaped florets will make loyal subjects indeed of garden pollinators, with bees and butterflies flocking from far and wide to appreciate their charms.

Alliums are perennial, reliably returning year upon year in the right conditions—so to get the very best from your bulbs, grow them in full sun, in a well-drained but fertile soil. For a truly royal display, why not underplant this stately Allium macleanii 'His Excellency' with the diminutive Allium karataviense 'Ivory Queen', for a contrasting effect that will undoubtedly turn the wow-factor up to 100!
