If a person was a diehard or just had some laying around, 1 inch foam board (the pink stuff) buried lengthwise (they come in 4x8 foot sheets) all around the banana bed would surely stop frost from coming through if you covered the top of the bed well. Its the same system they use on newer homes around here. After they pour basement walls, they insulate the EXTERIOR with foam board. Then you can frame and inuslate your basement walls with fiberglass batts. I believe people also use this method when they build greenhouses. A couple feed down, the ground never gets below 50F (around here).
