Serissa is a semi-tropical, almost temperate species that can take a little cold weather but not constant freezing temps. Sort of puts in a range of conditions that may explain why it can tolerate indoor environments. As soon as all threat of freezing temps. are gone, put it outside and it will begin to perk up.

Place it in a sunny window for the time being and bear with it while it adjusts to the new conditions. It will really shine during the hot, humid summer months. Just remember to bring it in again before the first frost.
