Ficus do good inside.
I doubt that a juniper would do well in the warm temperatures of the interior of a house.
I want to have a Juniper bonsai tree in my room to add a tranquil element to my room, my room gets ample sunlight and with the blinds open the room is completely illuminated. I'm wondering if I do get a Juniper bonsai, that if I keep it like this in my room (where I want it to be), will it die?
