The impressively large, lillipop-shaped flowerheads of Allium 'Round 'n' Purple' are made up of masses of dense pretty, silvery purple star-shaped flowers. These enormous blooms, which are one of the largest in the allium family, are supported on strong upright stems. The leaves start to die back before the flowers appear so best planted amongst perennials in large groups for maximum impact.
Allium bulbs are easy to grow in a sunny spot with freely drained soil, or a good quality potting compost. Ideally they should be planted in September or October, but could also be planted in early November in milder regions. While keeping the size of the flowerhead in mind and avoiding overcrowding, dig holes roughly three times as deep as the diameter of the bulb and place them at the base, pointy side up before gently infilling and watering to settle them in. In early spring, as growth begins, apply a balanced, slow-release fertiliser, and allow the plants to die back naturally and completely before tidying away.
