Jonna, I'll try to get some seeds for you. I'm normally not very good about collecting seeds, but I'll do my best. Remind me if you would.
When I researched the plant, I found the same varying information that you found. I actually got the seeds in trade last year, and the plant was highly recommended by the trader. She loved it. I wintersowed it last winter so it hasn't bloomed yet, but it's breaking dormancy now and looks nice and healthy.
