I keep getting questions from folks wanting to
know the difference between Egyptian onions, potato onions, shallots,
and multiplier onions. All are perennial onions that reproduce by
bulbs, and it's easy to confuse them.
Egyptian onions (also known as walking onions) are easy to
distinguish because they reproduce by little bulbs at the top of leaf
stalks. They don't make big bulbs, so are best eaten as green
onions or scallions.
"Multiplier onion" is a term used to refer to any onion that reproduces
by dividing its underground bulbs (just like garlic does.)
Multiplier onions can be separated into two categories --- shallots
(which form bulbs up to 1.5 inches in diameter) and potato onions
(which form bulbs up to 3 inches in diameter.)
We're growing potato
onions for the first time this fall, and I have to say that I've
already decided I love them.
I carefully planted them in raised beds a month ago and mulched them
heavily with leaves. Then, just as everything else in the garden
and
woods was turning brown and dying, the potato onions shot up fresh,
green sprouts.
Hooray for perennial onions!
