Hmmm... Well I know it wasn't you Stephanie because you have great success growing from seed from what I've seen~especially wintersowing!! I'm guessing they really are just difficult to germinate. It seems to contradict their invasive status, in comparison to many others.
Sooo I will have to look around. the article you posted talked about a certain kind of comfrey, I'll go back and see and go from there.
Thank you all.
Christine
