What seeds last the longest?

Online Answer
Most last for a couple of years if stored in a dry, cool place. I have learned from experience that onion seeds are not much good after the first year, but tomato, cucumber, and melon seeds can last 5 years or more. Brassicas and squash seeds are good for 4 to 5 years..
