The seed pods are where the flowers were. They trun brown and then open up and you can see the 1/8 inch hole in the top. You can literally shake out the flat black discs in your hand like big pieces of pepper. It's pretty easy once you figure out how not to dump them all over.

I just throw the dried flower heads into a paper bag and shake well.Take the flower heads out and pour the seeds onto a paper or whatever and remove the rest of the chafe.
