Last message should have read as follows. Sent out too quickly.
Both of the these areas were iris grow have winter vernalization
temperatures. I checked Weather Underground history and they have
vernalization temperatures.
In northern Italy they are in mountains.
Shaub Dunkley , There is a lot of good internet sites that can give
you more
information on plant biology, bloom triggers vernalization etc. It is
good that you are trying to understand all this. Good luck.

Interestingly, the Dalmatian coast and northeastern Italy, home of
pallida, are not considered a Mediterranean climate, but are classified
as humid subtropical, same as the southeastern US.

Part of the biological needs for iris is a winter, for vernalization.
"Mediterranean climate, major climate type of the KÃppen classification
characterized by hot, dry summers and cool, wet winters and located
between about 30Â and 45Â latitude north and south of the Equator and
on the western sides of the continents. In the KÃppen-Geiger-Pohl
system, it is divided into the Csa and Csb subtypes"
Warm climates without cool enough winters will not be able to trigger
vernalization needs, and short circuit biological signals.
