    Spherical flowerheads made up of numerous star-shaped, deep violet flowers appear in summer. These enormous flowerheads, measure up to 15cm and look great in pots or borders where they can be seen in their full glory. They are also perfect for a sunny border, dotted in groups among ornamental grasses, or as part of a Mediterranean scheme. Alliums look best planted between medium-sized herbaceous plants, which help to mask the strap-like leaves, which fade by the time the flowers appear.

  • Garden care: Avoid excessive moisture from late summer when dormant.
