Thanks, Jane, for the information - Greek friends we have spoken to here have told us that the saffron from C. oreocreticus is poisonous, as is the whole flower. Goats certainly seem to irgnore it here. I was so devastated by the sight of the ploughed field, so your info has cheered me up a lot. It seems that once ploughed, nothing was done with the field - no crop seems to have been sown - so maybe the farmer lost interest. We will certainly collect some seeds when the opportunity arises. Another threat, of course, is the Oxalis pres-caprae which is becoming more of a problem each year. I uunderstand we aren't the only ones with this noxious weed. In some places it is in flower already - south coast around Ierapetra.
