Alliums, known as flowering onions, bring eye-catching shapes and colors to your garden. These late-spring to early-summer-blooming bulbs are in the same family as garlic, shallots, chives, and onions, but they're grown for their unique ornamental value. Alliums are available in a variety of colors (pinks, yellows, whites, blues, and purples) and sizes (from 10-48"), their tall stalks topped with spherical blooms creating lovely texture in the garden or dried arrangements. And like their edible relatives, alliums are deer and rodent resistant.
