Perennial onions ship in the fall: September - November. We ship to northern-most areas first. Shipping surcharges apply - $2 for one item, $4 total for any two or more fall shipped items (including garlic and woodland medicinals).

How to Grow: A Garlic & Perennial Onion Growing Guide will be included with your shipment of bulbs.

Multiplier onions are hardy, productive perennials. According to the National Gardening Bureau, multiplier onions can produce a larger yield per area than any other vegetable except staked tomatoes. Multiplier onions produce a cluster of bulbs at ground level from a single planted bulb. The larger bulbs are saved for eating, and the medium and small bulbs are stored and replanted. Both potato onions and shallots can be grown in pots for forcing green onions during the winter. Multiplier onions exist in two horticultural forms: potato onions and shallots. Shallots may be distinguished from potato onions by the shape and division pattern of the bulbs. Shallots vary in their ability to produce seed, but potato onions rarely produce seed. There are several advantages of growing multiplier onions: (1) They are not as readily bothered by the onion fly as are seed onions. (2) Once you have enough potato onions or shallots you need not buy seeds or sets again. (3) Some types of multiplier onions are in demand as gourmet items in restaurants. (4) Potato onions and many shallots store well, and can withstand subfreezing temperatures in every area of the continental U.S. when properly planted.

Starter Package: Perennial onions are sold by weight rather than bulb count. Bulb size varies according to crop conditions and bulbs are usually supplied as mixed sizes. Your starter package includes a free 4-page growing guide which covers perennial onions and garlic.

Shallots: Shallots are planted and harvested in essentially the same manner as potato onions. They have a delicate, mild flavor and some varieties are especially valued in gourmet cooking. Our shallots are widely adapted and do not require special day lengths to yield well. Note: Shallots are shipped only in September and October.
