Here's a bit about collecting seeds.http://flowergardens.suite101.com/artic ... ower_seeds
"Patience! Seeds Must Be Mature
Wait until the seeds mature before you collect or harvest them. Avoid seeds that seem damp or soft or moldy or harbor insect pests.
Keep Seeds Dry
Work on a dry day after the dew has dried in the garden. It is very important to keep the seeds dry from now on. I like to knock them into a paper bag or paper envelope for easier handling. Label the seeds as you go. Allow them to air dry indoors at room temperature in a flat layer on a piece of paper for another week or so before storing.
How to Store the Seeds You Save
Store your seeds in a cool, dark, dry place. I have stored seeds successfully in paper or glassine envelopes at cool room temperature in the back of a desk drawer. But a more reliable place is to put the envelope of seeds inside a closed container such as a glass jar with tight fitting lid, or a zipper style plastic bag. Then put the jar or bag in the refrigerator where the temperature is cool and relatively constant. Seeds stored this way should remain viable for a year or two -- or even longer. See also How to Test Seed Viability.
Using A Dessicant
Some gardeners enclose a dessicant inside the jar along with the seeds to make doubly sure the seeds are dry. You could use a little packet of silica gel (such as those included in the package with new electronics or leather goods.) Or, make your own using a spoonful of dry milk powder wrapped in a piece of paper towel. This should absorb any excess moisture inside the jar.
CAUTION: Seeds Are Alive!
Seeds are living things, so treat them with care. Do not crush or damage them. Do not let your seeds freeze (or overheat) while in storage. Be sure they stay dry. If they become moist while in storage they may try to grow prematurely and then die. Although seeds can sometimes survive extended periods of storage, it is usually better to plant seed sooner than later because germination rates decrease over time.
Record Keeping for Seed Savers
Label each envelope or packet of seeds with the plant name and/or description, the date you collected the seed, and where the seed came from. You may want to keep a master list so you know specifically which seeds you have on hand and how long they have been stored. You could also record this information in your garden journal, if you have one. (See Keeping A Garden Journal.)"
