Evening primrose transplant

I am new here as well as a newbie in growing and using herbs, my first question is the following: I have an evening primrose plant which has grown quite tall lets say 20 to 24 inches high. I have had it in a vertical garden outside but with snow and frost fast approaching I am concerned on how I can transfer it into a pot. the plant has grown sideways because of the way the pallet was hung so i am not sure if there is a way to entice it to grow straight or how to transport it indoors without killing it.

Thank you for your help.
