Seeds which need stratifying, need to be in a moist medium.
You could do this by placing the seeds in a small plastic container of vermiculite.
Make the vermiculite moist,but not wet, and sprinkle the seeds onto it.
Place the lid on the container and place in freezer for that time.
I usually allow the seeds and vermiculite to sit overnight at room temperature so the
seeds "imbibe" the moisture , before they go in the freezer. Maybe in Florida a few hours at room temperature would be fine.
