I did not think about stratification at all. I was going to look into germination of every plant when I get seeds. (I have germinated A. peregrina already and rest are on the way)

I have pretty big yard that I can use to grow plants on so I think I can fit every one I am thinking about growing. I am not going to keep every plant when fall comes. Those that can be harvested then will die like Leonotis and Salvias and rest will overwinter indoors on window sills or in grow tent.(I live in 60N lattitude)
