If you are looking for a large, tropical houseplant to add to your home then the Philodendron xanadu (Thaumatophyllum xanadu) is an excellent choice. Easy to grow with lush foliage, this Brazilian native is known for its large, multi-lobed leaves and bushy growth habit.

Until recently, this plant was considered a philodendron, hence its common name. However, in 2018 the philodendron xanadu, along with several other plants in the philodendron genus were reclassified into the newly created Thaumatophyllum genus. Unfortunately, despite this reclassification, the xanadu is still considered toxic to pets and humans if ingested so take care with this houseplant if you have furry friends or small children at home.

Philodendron Xanadu Care
Like many other plants in the Araceae family, the philodendron xanadu grows well in standard household conditions, making it an excellent houseplant. It is relatively low-maintenance, enjoying medium to low light and semi-regular watering. It does not require any pruning or aggressive repotting and is not prone to any particular pests, diseases, or other problems. Here’s what you need to know about growing this tropical plant indoors.

Light
As a forest understory plant, the xanadu is accustomed to receiving several hours of indirect, dappled light every day. As a result, it does best in bright, indirect light when grown indoors, although it can tolerate short periods of low light as well. Be careful not to expose this tropical plant to extended periods of intense, direct sunlight as it can develop leaf burn.

Soil
Choose a soil mix that is rich, airy, and well-draining while still retaining some moisture. A combination of equal parts indoor potting soil, perlite, and orchid bark is a great option that you can easily whip up at home. Alternatively, any ready-made soil mix that is designed for aroids is a great option.

Water
Allow the soil to almost completely dry out between waterings and then water your philodendron xanadu thoroughly. Ideally, you should be watering your plant until water drains from the pot’s drainage holes (houseplants should always be planted in pots with drainage holes). Ensure all excess water has drained from the pot before returning it to its original location.

Like most houseplants, it is generally better to under-water a philodendron xanadu than to overwater it. These tropical plants are sensitive to overwatering and can develop root rot if their roots are left sitting in water.

Temperature and Humidity
For the most part, standard household temperature and humidity levels are fine for a philodendron xanadu. That being said, these tropical plants do enjoy humid conditions where available, so providing your xanadu with an extra source of humidity will always be appreciated. Try placing a small humidifier nearby or moving your plant to a naturally humid room such as a bathroom, kitchen, or laundry room.

Fertilizer
In spring and summer, fertilize your philodendron xanadu with a balanced liquid fertilizer once a month. Ensure you dilute the fertilizer before applying it to prevent fertilizer burn.
