Broccolo Spigarello is another VERY cold hardy green. I don't know how cold it is willing to germinate, but once the seedlings are hardened off, they can take it down to 25 F (7 degrees below freezing).
I had a patch that overwintered without any cover or evident discomfort, and i thought it went below 20 that winter! Then it burst into bloom early in spring.
It's called a "leaf broccoli" and the broccoli flavor is strong (but not bitter like rapini). The young leaves and thin tips are the edible parts. you can get some small, brocolli-like heads the spring after the main crop, but I never tasted those. I wanted the seeds!
