As I mentioned in earlier correspondence on this topic, my experiences
is the same, but based on far fewer samples. I have kept seeds inside
the bouse and outside under extremely cold conditions and the
germination appears to be equal. I would qualify this by saying that
most of the seeds have been species irises rather than TB.
