This is some black seeded simpson lettuce I planted around Thanksgiving. I figured I could get one last harvest for the year in my cold frame, but shortly after I planted it, it got really cold for about three weeks straight and I assumed whatever might have started to grow was surely dead. I didn't think much about it all winter long, but a few weeks ago, I noticed from my window that it looked like there was something GREEN in my cold frame! Sure 'nuff. I actually thought it might be really bitter, having survived a deep freeze and having been planted since late November, but it was actually really good.
