hello Meditteraneus
I have tried searching in italian websites ... they generally recommend starting with small bulbs ...however, in addition to what others have already written above, I can add that the sowing must be done in a very draining soil (they recommend adding peat and sand) and, because their southern origin, I would try to sow in pots in a cold frame now and i I would wait next spring(2015) before transferring them outdoors permanently, perhaps burying it more deeply and over a sand bed ( do not like their roots remain in the damp)
I apologize for my "monday english" 8)
