Plants in the genus Allium are bulbous herbaceous perennials. Flowering alliums are closely related to alliums we use in the kitchen – garlic, onion, leek, chive, shallot, and scallion. Regardless of species, alliums all produce umbels of starry shaped white, pink, blue, or purple flowers.

Flowering alliums have become beloved ornamental garden plants. Native to Central and western Asia, flowering alliums are grown by horticulturalists worldwide. They are hardy in USDA zones 5 to 8 and are grown as annuals elsewhere. Alliums bloom abundantly in late spring and continue through summer. Their bunches of small flowers attract pollinating insects to the garden.

Popular cultivars are Allium giganteum, Allium hollandicum, and Allium sphaerocephalon. They put all their energy into producing large, round, purple flower heads rather than big, fleshy bulbs, like culinary alliums.

Flowering alliums prefer growing in full sun and require consistent moisture but good drainage so that the bulbs do not sit in water and rot. Plant allium bulbs in the fall. Plant them about 2 to 4 inches deep, in rich, composted soil to achieve the best results. One can also grow them from seed. The plants grow up to 5 feet tall.
