Here are some suggestions from Seed Savers (www.seedsavers.org) and other sources on how to label seed packets and save seeds. The Seed Savers website is an extensive source of information on seeds.
Seed Packet Suggested Information
- Seed’s name and the specific variety and/or color,

How do you save seeds?
A rule that is easy to remember is CDCD, which means clean and dry plus cool and dark. You can use the original packets to keep the labeling information. If you put the seeds to another container, try to label them with as much information as you can. Remember it can take weeks for seeds to dry before sealing them in a container. It doesn’t look (or smell) good if next season you find them molded.
You can place leftover seed in paper envelopes. We use coin envelopes a lot. Then place them all in something airtight, like a plastic container. Another method is using sealable jars or medicine bottles. Uncooked rice in the bottom of the container can absorb excess moisture, just put a paper towel between the seed and the rice. Now store them in a cool, dark area such as a cool basement area or the refrigerator. This is where airtight is important. You use the freezer only if the seeds need cold-stratification.

Seeds Life Expectancy
The tables below takes the average life expectancy of seeds from a variety of sources, including the cooperative extensions of Oregon State University, Colorado State University, Purdue University, and Virginia State University. Consider it more as a guideline, as the longevity of your seeds ultimately depends on the date on the packet and how carefully you’ve stored them since then.
