Hi Umbrian. Exactly the same situation here in Rome re seeds. Disastrous year :-( Widely/wildly fluctuating temperatures prevented many seeds from germinating at all. Crepis rubra, which should have germinated in February and be setting seed now only germinated about 10 days ago. And then I only got 5 seedlings. Then from an average daily temperature of low 20s centigrade with cloud we jumped to low 30s with full sun within 2 or 3 days, Needless to say, said seedlings frazzled. Similar story with Ipomeas but at least I have one or two plants established of a couple of types. Other seeds, not a murmur. Tithonia rotundifolia germinated and rotted in waves with the cold and torrential rain. My last seed sprouted a week ago and, with the summer heat we are having, should survive. One plant out of about 20 seeds. :-( I could go on and on but I think you get the picture. A terrible year for seeds.
