I’itoi Multiplying Onion Bulbs

Type: Heirloom perennial
Size: Starter bulbs (small multiplying onions)

Allium cepa var. aggregatum (I’itoi). A traditional heirloom onion grown for generations in the Southwest. These unique multiplying onions grow in clusters underground, producing more bulbs each year once established.

I’itoi onions multiply below the soil, forming tight clumps of small, flavorful bulbs. The green tops can be harvested like chives, while the bulbs can be used fresh in cooking.

These starter-size bulbs establish quickly and begin multiplying, making them perfect for building your own perennial onion patch.
