It's simple. Just let a few flower heads dry on the vine, run your thumb through the center, and voila, hundreds of seeds. Place in an evelope and label. Plant in the spring after danger of frost.
Use a wire tea strainer. Put the flower heads in the strainer over a container, pan or something to catch the seed. Mash with hands. You can see the tiny seed, store in paper bag or if they are very dry in a zip lock bag, good luck.
