I'd try putting the flower head in large containers without lids, to dry
out. When the flowers are dried out, shake the heads to free the seeds and
collect the seeds in paper bags. Label bags and store in the fridge.
Other than that, you could do the same as herbs. Tie the plants together and
hang them upside down over a sheet or newspapers( can be done inside) and
wait till the flowers are completely dried. Collect the seeds the same as
above.
Thanks!
