Lucy, I read an article by Paul Black a while back. Put the seeds in the pots, buried the pots outside over winter, got 3 seeds to germinate, all from the bee pod, none of the others came up. One of the 3 survived. still waiting on the remaining one to bloom, might happen next year. I have one that came up as a volunteer years ago, and is a nice purple self with loads of fragrance, a whitish beard and some white marks near the beard. The one remaining seedling is from this purple volunteer, so it will most likely be just another purple self. I'd like to get one of my crosses to germinate. Last year out of about 20 attempts, I got no seed pods. Guess I'm getting worse at it.
