Is it possible to grow broccoli in the wintertime?

Where there is a will there is a way. It takes more in the Northern climates, but some determination and experimentation can lead you to the solution.
Google for winter hardy varieties of Broccoli. If you make a hot bed-lots of hot manure in the bottom, top with potting mixture, or put pots of dirt with the plants on top. Cover up with row covers or plastic as needed.
You could also try a miniature greenhouse a top a raised bed using flexible PVC type pipe over rebar stakes at the corners, with plastic over it all. Maybe even hang a 100 watt bulb in there on the nights when extra heat is needed.
If you get sunshine, you can take dark containers of water, and let the sun heat them up and they will release the heat at night. Rock or concrete blocks can do the same thing (surround the bed on the North, East and West sides and leave an opening on the south side for as much sun as possibleon the plants).
