Hi, as the donor of the Narcissus seeds, I would recommend to sow them in
early autumn when temperatures range from 15 to 25°C. Those would be summer
temperatures in many places,  I know. They surely can endure -5° or less in
the wild once they have developed the first and only leaf of the first
growing season, but I advise to protect them against temperatures below

I would stop gradually watering or keep away from rain in May so they go
dormant, then keep them dry  with an occasional light watering to mimic
summer storms, then water normally in September to October, depending on

Some species need moisture around the bulbs during summer rest, like
cyclamineus, jonquilla, nevadensis/longispathus and very likely
pseudonarcissus and poeticus.

Good luck.
