An impressive sight in late spring and early summer, when the tall, upright stems emerge, each topped with a dense rounded cluster of small star-like flowers. It can be used to add height, colour and structure (without density) to mixed borders, and it also looks great when teamed with ornamental grasses in less structured settings. The flowers are a magnet for bees, and they're long-lasting when cut for the vase. Try to plant them amongst plants with low, leafy growth, as these will help mask their leaves, which die back before the flowerspike emerges.
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.
