Answer: If stored properly (steadily cool and dry), pepper seeds should be good from one year to the next. They might last up to four or five years, but the germination rate will decrease with time to the point where you will want to replace them. Viability varies from plant to plant, so some seeds such as corn should be replaced every year while others such as tomatoes and peppers will last longer. For best results, keep the seeds in an airtight container such as a closed jar in the refrigerator.
