Kristi, also each winter can be different, I had a kalanchoe that lived one full year outdoors, but then we had an especially cold winter and it died, leaving no babies...although I didn't cover it or do anything with it to try to save it, so I think it could have lived if I'd taken precautions.
Arif, your winters are colder there, even though you're in Zone 9, odd thing! And definately warmer in summer than me, Seattle stays mild in summer, no humidity, unless in the form of light misty rain, and rarely into the 90's F - so many perennials do great here!!
