Answer: Most seeds should be stored in a cool, dark place in an airtight container. Some seeds, especially those of warm-season vegetables such as tomatoes and peppers, will be damaged by freezing, so it's best to keep all seeds out of the freezer!
Seeds will remain viable for several years if placed in a jar with a screw-type lid and stored in a dark place where temperatures remain stable. I always store my jars of seeds on the floor in the back of a seldom used closet.
