I start mine in mid January. They get 'haircuts' over their course of life under the lights and then in the cold frame. I usually plant mine out in mid April plus/minus a week. The plants were too small last year so I moved my start date up to mid January for this year and it worked out well. Since you don't transplant onions like tomatoes, I like to start them in a container about 2/3 full of a high quality soilless potting mix with nutrients and then the top 1/3 with my soilless seed starting mix.
I'm guessing you could eat the seed stalk although I never have.
