A Xanadu is often wider than it is tall, reaching a height of 2-4ft. and a width of 3-5ft in ideal conditions. The leaves of this beautiful, exotic looking foliage plant can be as large as 16″-18″ long and 7″-14″ wide. Unlike many philodendrons, the Xanadu is an upright plant not a climber or vine.
