The Giganteum allium is true to its name. Towering at up to 5 feet tall, these lollipop lookalikes will really make your late spring and early summer garden stand out! Their gorgeous globes are made up of clusters of tiny, star-shaped purple flowers. Bees and butterflies love them, and their onion-y aroma keeps the pests away! Giganteums look great as a garden backdrop. They are perfect in flower arrangements, too—fresh or dried.
