Yours looks identical to mine. Right down to the lighter shade of green on the new growth(same with his?) I assume its the maki one. The ones sold in the florests may not be the hardy form? I havent run a DNA test and dont have papers for it. Ha!
Looks like yours is inside for winter as well? If its always inside it'll need lots of light.
Mine is in a cool spot but with lots of natural light even at this darkest point of the year,
Mine I trunk chopped and most of the cuttings took. So Ive got a bit of an experiment going. Some inside under lights and others with the mother plant and the rest outside. I still havent stowed those away with some protection but it still hasnt frozen yet.
