Allium giganteum
Best statement flower for gardeners seeking low-maintenance, pest-resistant vertical interest.
Get ready to be amazed by Allium giganteum! These flowers truly live up to their name as they are huge, reaching impressive heights of 4-5 feet. They create a stunning visual impact with large, round balls composed of perfect little purple florets atop sturdy stems, almost like a topiary. Adding these Alliums to your garden is sure to turn heads and grab attention. For a more contemporary look, try planting them in large groupings, or scatter them periodically throughout your garden beds. They typically bloom in late spring to early summer. The Allium family, which includes onions, leeks, and chives (Allium means 'onion' in Latin), has some beautiful members, and these giants are certainly among the best-looking! Experienced gardeners often plant several bulbs close together, remembering to place them near other perennials whose foliage will help cover the Allium's base as its own foliage fades. They bloom beautifully, towering over other flowers during their late spring to early summer show.

Know before you buy
These impressive bulbs typically grow to a height of 4 to 5 feet. Because of their significant height, they are best suited for the back of a garden border or as a focal point in a landscape.
It is common for Allium foliage to begin yellowing as the flowers reach peak bloom. To maintain a tidy appearance, plant them behind shorter perennials that will grow to hide the base of the Allium stems.
Yes, Alliums are part of the onion family, and their scent is naturally unappealing to deer, squirrels, and other common garden pests. They are an excellent choice if you have had trouble with animals digging up or eating your other flower bulbs.
Absolutely. Their sturdy, tall stems make them excellent as cut flowers for tall vases, and they also hold their shape well if you choose to dry them for long-lasting indoor decor.
Allium giganteum bulbs should be planted in the fall before the ground freezes. This allows them to establish a strong root system during the winter so they are ready to bloom in late spring or early summer.
