I obtained this small tree from a friend. It has spiky, shiny leaves, soft to the touch, and delicate stems. New leaves are lime green, gradually darkening as they grow larger. Older leaves are broad at the base and narrow as they get closer to the tip. The original trunk was cut, revealing a hollow center, almost like bamboo.
I've owned the plant for about 1 year, and in that time it hasn't produced fruit or shown any signs of flowering. Broken branches placed in water haven't grown roots. I live in Southern Canada, and I'm reasonably certain the plant is tropical or semi-tropical (not native).
