Bananas are without a doubt one of the most economically important plants in the world, so it makes sense that most people don't often think of growing them indoors. That's a shame, though. Because of the way banana plant grow, you can create a stunning, large, and very tropical summer container display with a banana palm. Assuming you fertilize and water it often, the banana plant will grow extremely fast, filling in your bright corner or window in no time at all and providing a wonderful conversation piece.
