About Gladiator - Allium Bulbs (Giant)


Seed Type Bulb
Plant Type Giant
Also known as Giant Onion, Ornamental Onion, Flowering Onion

Add some whimsy to your garden with the lollipop-lookalike Gladiator allium! Plant the bulbs in the fall in a sunny spot, and watch them bloom in late spring or early summer—and grow up to 4 feet tall! Each softball-sized head contains dozens of tiny reddish-purple flowers. As with all alliums, the Gladiator belongs to the onion family, and the telltale scent does a great job warding off rabbit, deer, and other curious critters. Bees and butterflies love alliums! Plant Gladiators in groups for the best visual impact. They look amazing in borders and along walkways, and are perfect in flower arrangements.
