I have obtained seeds of Iris iberica subsp. iberica. I have read that they
have a low germination rate and that specialists resort to forced
germination using the arillusom incision method. I am certainly not able to
practise this method. I would therefore like to know if there is a simpler
method to promote germination. Is it true that the seeds must be stratified
in winter? So when should they be sown?
