I have a Paeony (Ludlowii 'Lutea') that I started from seed about 9 years ago. I let it produce a few seed pods and was going to try and start some more. I am not sure whether the seed campsule is to turn brown (from green) and split and this is when the seeds are ready? Do not to pick them off too early. The Paeony I started was not done with any expertise on my part and if anyone has a tried and true method of propagation, I would very much appreciate any info? Do these seeds germinate better if sown as soon as ripe, as so many seeds seem to do? Thank you for any feed back.
