What are the pros? Everything
What are the cons? Nothing. Perfect onion.
I'm very far up north in Quebec, in Abitibi, yet these overwintered without any protection beside the snow cover. The first year they behaved like normal green onions, but the next spring, those I left in the ground started dividing. Sadly I lost them to the onion flies but I'm going to grow them under cover now. They will be a permanent presence in my garden!
