Answer: In addition to asparagus which is exceptionally long lived, rhubarb, Jerusalem artichoke and horseradish are perennials sometimes found in vegetable gardens, and strawberries can be kept for several years if the beds are well maintained. Other fruits such as the brambles and blueberries are also long term plantings. Herbs such as sage, thyme and oregano are perennials and will last for at least a few years. For some reason it seems most of the typical vegetables are annuals.
