Louisiana Evergreen shallots
 

Does anybody know where to get a start for these, and how far north will
they survive the winters? (I'm in Minnesota now, zone 4)

I just (in the past year or two) figured out that the green multiplying
onions we used to grow in SE Texas were really shallots, and probably
"Louisiana Evergreen" variety because they never bloom and never
actually bulb. They just keep dividing forever; you pull up a little
clump for your salad and put one back in the hole. If the clump gets
too big, you divide it and give a start to your friends. I've grown
scallions, and they don't taste the same. And regular shallots don't
multiply without bounds.

I drove by my Grandma's old house a couple of years ago when I was in
Houston to see if there were still some onions growing there. The house
was still there, but none of her plants :-( (Not that I expected
anything, but I had to check)

I might try planting shallot seeds this year and see what happens. They
/could/ be a decent substitute...
