No, I'm afraid not. They're a half-hardy tropical climber, so need a heated glasshouse or conservatory. They can only be kept outdoors in summer.

Don't bring it indoors all at once. Slowly acclimate it to indoors an hour each day slowly increasing time inside. That will reduce transplant shock.

Bougies can take temps that low, but only for a few hours at a time. Night after night of freezing weather is beyond their tolerance.
