Answer
Jeanne, most seeds will stay viable for 3-5 years if kept dry and at temperatures between 35F and 40F.  

I personally keep mine in ziplock bags stored in a sealed tupperware container, which I keep in the back of my refrigerator.  Although germination rates will decline every year by around 10%, I simply sow a little heavier every year to compensate.

Attached is a table that will assist you in determining the average life span of most vegetable seeds.  Flower seeds generally last up to 5 years. (Please forgive the formatting of this table should the numbers not line up. This website does not allow for tabs.)

Seed Type     Years     Seed Type     Years
Asparagus       3       Muskmelons      5
Beans           3       Onions          1
Beets           4       Peas            3
Broccoli        5       Peppers           2
Cabbage         5       Pumpkins        4
Carrots         3       Radishes        5
Cauliflower     5       Spinach           5
Corn            2       Squash           4
Cucumbers       5       Tomatoes        4
Lettuce         5       Watermelons     4


I hope this answered your question.  Please write again if I can ever be of assistance.

Mike
