Potato onions, also known as multiplier onions, and shallots belong to this group. An aggregate cluster of several bulbs from a master is formed by a single plant, and the bulbs are smaller than those of common onions. They are engendered solely from girl bulbs, despite the fact that multiplication from seed is conceivable.

Shallots are the main subgroup inside this gathering and involve the main cultivars developed financially. They aggregate into small, ovoid to pear-shaped clusters of bulbs. Potato onions vary from shallots in framing bigger bulbs with less bulbs per bunch, and having a straightened (onion-like) shape. There are intermediate forms.

I’itoi onions are grown in the Baboquivari Peak Wilderness in Arizona and are a prolific multiplier. This variety of small bulbs has a flavor similar to that of shallots, is simple to grow, and is ideal for hot, dry climates. In the fall, bulbs are planted 25 millimeters (1 inch) below the surface and 300 millimeters (12 inches) apart.

During the cooler months, bulbs can be harvested because they will multiply into clumps. In the heat of summer, tops die back, and heavy rains may bring them back; The bulbs can either be planted in the fall or harvested and stored in a cool, dry location. The plants seldom bloom; Division is the mode of propagation.
