Common name: Ornamental onion
Alliums include many familiar edible plants such as onions, leeks and garlic as well as attractive flowering types. The ornamental types are a great addition to the garden with their showy flowerheads in shades of blue, purple, white and pink, bringing globes of colour in spring and early summer. They are good cut flowers and the dried flowerheads give a long lasting display.
