Do they need cold for germination? I have successfully germinated seeds o=f
flavum, I know this is easy, without any cold treatment.
I plan to look at several different species of seed over this winter to s=ee
if there is any difference in cold vs no cold treatment. Will let everyon=e
know of outcome next year.
Cold for long term storage, maybe?
