Philodendron ‘Xanadu’. Xanadu philodendron has a tropical pedigree that thrives indoors and in warm-weather landscapes. Unlike other varieties of philodendrons, they grow in clumps rather than climbing vines. Xanadu philodendron can reach a height of 60 – 120cm with a width of 90 – 150cm. This plant is easy to grow and increases in elegance as it ages.  Philodendron ‘Xanadu’ is the hardiest of all philodendrons for the New Zealand climate.  Grows best in a very sheltered & frost free position outside.  Enjoys semi shade conditions.  Great for indoors, a warm bright bathroom or hallway. Low water requirements.
