Great if it's olive! Local conditions should be great for it! Btw, I don't keep it inside, just brought it in for photo cos it was dark outside
Don't olives usually grow alternate leaves? (I.e. one to left, next to right?) This one seems to make four leaves per node, or 2 opposite leaves, an next set growing perpendicularly to the first really close by. Also, leaves are much smaller and finer than regular olive, so this would be some nana variety?
