Does anyone know how to harvest seeds from this plant? I just got one at Annie's Annuals and it's getting to the end of it's flowering. There's little dried pods where the flowers wither, and occasional I see one tiny hard black thing at the end of the dried up stamen. I assume that's a seed, but I'm honestly not sure. I can't find much info on harvesting seed from this plant. It's monocarpic, so I'd really like to get some seed to propagate, because it's quite pretty, and tough.
Thanks in advance if anyone has info-
