You might improve chances of the jellybeans surviving if being outside they could be in a spot that offers some protection from frost, wind, or cold air in general. I tuck my pots against the house, sometimes under the eaves and if temps look to drop close to freezing, I drop frost cloth on top of them (sometimes doubled folded shade cloth) just to help protect from frost. I notice you are in zone 7 so colder than where I am. If you divide them, put them in different locations to increase chances of some of it surviving somewhere.
