I would not plant this now. It will not be able to establish while it is cold and will be killed by the winter weather. I would wait until it warms up in spring. Keep it in a cool place such as the garage till spring and water sparingly.

If it was a gift azalea (from a florist) meant for indoor growing it can't be planted outside. But you can grow those indoors.
