Larspur seed

This was a Friday Problem on 7/4 which turned out to be larkspur (maybe even Belladonna Larkspur 'Delft Blue'.) I really like it so I went seed hunting. Some of them had already split open, which is fine as I would not mind some more plants where it is.

I did manage to save some pods which have black seeds in them. I am going to let them dry a bit and them take the seeds out. I need to read up on whether these need to be stratified, but I am guessing they do.
