Wait until the seedheads are really dry if you can, and ready to pop.
The seed germinates very easily. but the resultant plants could take a year or two before they flower (or even more). A sprinkling in a flower pot, sown immediately after harvesting, yielded about 60 plants, and I ran ouit of space to prick them all out.
I put a mound of leaf mold around the crowns, and a marker peg because the leaves of mine die away - the marker peg helps me remember where they are!
They also have roots that love to romp, so often flower better in a constricted space.
