"florist azalea's" usually only live indoors..
They are not hardy to freezing temps..
Treat them as a houseplant... or can live out
doors come summer time and brought back in in the
winter...
If you're adventurous and they're reasonable in price, because of me being an experimenter...
If you really wanted to see if they'd be okay outdoors, buy them, leave them in your house until no more frosts... and then find a place that might be considered a "micro climate" by the base of your house..
Something like a South facing, raised bed, patio/stones/cement by it to keep it warmed?????
You might get it to over winter, but it's hard to say???
Usually those kinds, say, anything you'd buy in a grocery store or florists are not bred to be long lived...
