Yesterday I was in the local blue and white box store across the border from me in North Carolina. Of course I walked through the garden area to see what what happening and I was happily surprised to see they had a rack of early vegetables starts. That's pretty early for zone 6b but I bought a six pack anyway. The variety is Bonnie's Best Hybrid, whatever that might really be. I probably have a pretty good chance with them since I have a small patch of the very same variety in still edible form in the garden now under a row cover. Even made slaw from one of them this week and it was fresh and crunchy. That's the closest I've ever come to year round gardening ever. BTW, the Alaska pea seeds I planted in January are a no show, so far.
