What kind of flowers can survive well in the winter months?
user
You have so many choices!  I’d suggest starting with carnations, as they do well in winters with temperatures from 40-70 degrees.  I would also recommend anemones and calla lilies.  In many regions you can also plant mums, if they are hardy.

Can the carnations survive outside or should I keep them indoors?
user
Indoor is fine for carnations, I would not recommend outdoor because of the freezing temperatures.

A single, mature carnation can survive outdoors in the right conditions.  The rest of your plants should definitely be indoors.
