Philodendron Xanadu Plant

The Philodendron Xanadu, sometimes referred to as Philodendron “Winterbourn”, is a large compact easy to grow plant. Each shiny, green, leathery leaf has 15-20 distinct lobes. A Philodendron 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. These plants are considered poisonous and should be kept away from pets and children.

The best part is the older a Xanadu gets the better it looks.

Plant Care


A Philodendron Xanadu needs more light than other philodendron plants to maintain its compact appearance. It grows best in medium, indirect light. Too much bright light causes the leaves to become pale and bleached looking; too little light and the stems become elongated as the plant stretches towards the light. Direct sun burns the leaves.


Water a Xanadu thoroughly until the water drains out the drip holes in the bottom of the pot, and then allow the top 50% of the soil to dry out before watering again. Leaves turn yellow if the soil stays too wet. A Xanadu grows more slowly in the winter and requires less water.


Feed monthly in the spring and fall, every other week in the summer, and never in the winter. Use a balanced plant food diluted to 1/2 the recommended strength. If the leaves are getting smaller and new growth is slow, the plant needs more food.


Daytime temperatures 75° to 80°F ( 23.9°-26.7°C); nighttime temperatures 65°- 70° F (18.3°-21.1°C)


Philodendrons like high humidity but still grow well in regular household humidity.


A Philodendron Xanadu attracts aphids and mealy bugs. If the air is very dry, spider mites are also a problem.


Bacterial diseases, especially all varieties of leaf spot disease, are a problem for the Philodendron Xanadu. Root rot from over- watering can seriously hurt the plant and cause the plant to die. Cool temperatures, dry leaves, and good air circulation helps prevent diseases.


Use a potting soil high in organic matter that drains quickly.

Pot Size

These plants like to be repotted as soon as their roots start to fill the existing pot. Use a a container that has drip holes in the botton and is about two -three inches larger than the root ball.


A Xanadu does not require much pruning. If the plant is getting too large and taking over your room, remove leaves by cutting them off at the base of their stem.


A Xanadu is propagated by plant division. Read about this type of propagation technique in the Glossary of the website.
