A shallot is an onion that decided to be several onions. Instead of swelling into one bulb it splits into a cluster of small ones, each with a milder, sweeter, more refined flavour than a cooking onion. It's the allium you want raw in a vinaigrette, where a raw onion would take over.
How shallot fits zone 4's season
Zone 4b's frost-free window runs about 128 days, from May 15 to September 20. Shallot needs about 108 days from sowing to first harvest.
