When I was young, we had a clump of banana plants growing on the side of out house. In those days, we didn't have air conditioning, only evaporative coolers, we called swamp coolers. There was no way to recirculate the water in the cooler, so there would be a steady drip line with water running day and night. That drip line went into the clump of banana plants and they would grow spectacularly. I could lay on the grass and watch them grow. The plants would try to produce bananas, but Phoenix was hot enough in the summer but too cool in the winter. We never did get any bananas, just the flowers.
