Identification please

Hello,
Was given this plant before Christmas, have been watering it and seems to be growing nicely, new berrys coming as well. Could you please tell me its name and is it an indoor or outdoor plant? I see new leaves so wondering if it needs re-potting to a bigger pot, also how big will it grow?
Thankyou.

 

Looks like Christmas Cherry, AKA Jerusalem Cherry, etc., Solanum pseudocapsicum - Wikipedia

P.S. I think I can recall them being prone to infestation with whiteflies every time I tried to save one.

 

Thank You for that, I shall keep an eye out for infestation then.

 

I have grown these outside for a season or two, they are best in a warm spot, and not totally hardy.

Outside, apart from greenfly I doubt you would have any pest problems.

 

Hi Pete, Thanks for that, I do have a spot they can go in but wasn't sure if they were for outside, Thanks
