I think so, but they'll flower. I had leeks i never took out that seem to keep coming back. Now its like i have chives growing in my strawberry patch. Onions don't go well in a fruit salad.

Onions and leeks are supposedly good companion plants for strawberries. I have one of those three tier strawbery platers and I ususally plant Onions or Hot Peppers nearby to deter any bad bugs. I'm in Zone 8b. I can't help you on the perennial question but I ususally plant my onions every year (sets or seeds). I plan to try Garlic again this year but I have not had much success in the past with Garlic. I love garlic. I see you are from NY. I live on the gulf coast now but I am a native New Yorker (bklyn).

Evergreen bunching onions (scallion like) can last for years. They do flower in spring, but you cut off those stems and then they do their thing the rest of the season, spinning out new growth. I use them like scallions, cutting off what I want by reaching below the soil and cutting, leaving the root. They benefit from occasional digging and dividing of the whole clump and resetting in fresh soil.

Regular old yellow onion no, as that is not technically a bulb like garlic - if you can store and replant you'll get one plant like you had before, so why? You can try and replant scallion like garlic if you can store it that long. I don't have the same experience as frank with leek. Never happened to me.

I have Egyptian Walking Onions that are perennials. They send up a stalk that produces a clump of bulbils, which eventually gets big and heavy, and falls over, rooting itself a foot or so away from the mother plant, hence the "walking."

You can use the tops like scallions, or with proper care you can get the bottoms to "bulb up" a bit (though they'll never be huge). You can use the bulbils like little boiling onions, etc. The whole plant is edible, and you'll have onions forever. Pretty much the only maintenance is getting them back out of your lawn when they walk there, and returning them to the garden!

Thank you all for the answers! I think I will plant some leeks and try some onions...I am looking for a source now for the walking onion...sounds different, if nothing else! Donna

Check out potato / multiplier onions. You plant those in the fall like garlic. Also shallot sets can be planted in the fall. Between garlic, potato onions, and shallots, you should be able to purchase growing stock only once, as long as you save some to replant each fall!
