Some seeds can last for three to four years, such as: 1  asparagus. 2  beans. 3  broccoli. 4  carrots. 5  celery. 6  leeks. 7  peas. 8  spinach.
If the seeds were stored in a basement or root cellar, some of the seeds could be viable for twenty years. If they were left in a shed, most would be dead in a few months. How they were kept is the most important factor. You could freeze them indefinitely.
