Allium ‘Millennium’ is a fantastic mid- late-summer-flowering allium, bearing large, rounded heads of pink-purple flowers in June and July. Like all alliums, its blooms are extremely attractive to a wide range of pollinating insects, such as bees, butterflies and hoverflies. It's perfect for growing in a mixed herbaceous border and is best planted in large groups, where its glossy green foliage and large purple flowers will work perfectly with other flowering plants in the border.
Grow Allium ‘Millennium’ in moist but well-drained soil in full sun. Feed with a high potash solution after flowering and allow the leaves to die down naturally. Like all alliums, the spent flowers take on an architectural beauty into autumn and winter, so leave these in situ if you can.
