That's good to know, Kevin, since I have zillions of the little darlings. I should have taken the time to clean the seeds better so I could see what was mixed up in there -- just taking the lazy way out and not realizing I was creating a monster (or a monstrous horde)!
Did you keep track of any of the other parents? Or were these self crosses? And Julia, did you have any idea with your seeds? As far as I know, the Silverine is from you via Bev...
