How long do seeds keep in storage?

The shelf life of seeds varies depending on the type of seed and the conditions in which it is stored. In general, seeds will remain viable for longer periods of time if they are stored in a cool, dry place. Some seeds, such as those from annual flowers and vegetables, will lose their viability quickly and should be used within a year or two of purchase. Other seeds, such as those from perennials and trees, can remain viable for several years or longer. To maximize the shelf life of your seeds, store them in an airtight container in a cool, dry place away from direct sunlight. You can also extend the shelf life of your seeds by storing them in the refrigerator or freezer.
