How does she look??

First timer here. Was just wondering how much time you think she has left to flower? First frost is usually around the middle of October but I feel like she has a month maybe a little more to go, which would mean the plant would be out there past first frost. She is in a pot so should I try to insulate around her. Also she is bag seed so I have no clue what the flowering period is suppose to be. She has been flowering since about the last couple of days in August.
