There is no coffee grown commercially in the continental United States, but it could be done. In the event of a zombie outbreak (or whatever apocalypse you prefer), the man with coffee would be king.
Although actually a tree, coffee can be grown in containers, pruned regularly and trained to be a 3- to 4-foot tall bush. If left alone, some varieties can grow up to 40 feet. On most plantations, trees are pruned regularly and kept at a manageable height of 6-7 feet for abundant yield and ease of berry picking.
