When we were in San Antonio TX at the Riverwalk, I saw a large plant that was growing in segments around 8-10" in length, like bamboo. The segments were green. But the leaves were big and round, looking nothing like any bamboo I've ever seen. Since it does get cold enough for freezing weather in that area, it must be able enough to survive cold temperatures.
It was a very pretty plant, and you really didn't see the bamboo-like segments unless you looked closely, as the big leaves prevented that, except on close inspection.
Does anyone have any idea what kind of plant that could be?
