Is there a reason why you want to propagate from seeds and not bulbs? I have a few varieties of colchicums. How do you go about getting the colchicum flower heads to form seeds? I can propagate some seeds for you for free if you are interested in them and willing to pay me postage for them. I have these varieties:
Colchicum autumnale 'Alboplenum'
Colchicum autumnale 'Album'
Colchicum Byzantinum
Colchicum Tenorii
Some NOIDs
