Sturon may be a bit too big!

I tend to use Shallots for this purpose!

Next season I am going to have a go with some 'Potato Onions' I have been given.

I am led to believe that these are basically a cross between an onion and a shallot i.e. the are round like onions, but form clusters like shallots!

Then once you have a grown them you save some of the crop for the following year, so theoretically I won't have to buy setts anymore!

I have always used shallots, too!

Teegee, some "potato onions" are clumping members of Allium cepa, like shallots, and some are members of A. fistulosum, with a slightly more "garlicky" flavor.
