If you enjoy growing houseplants, especially philodendrons,then you may want to consider adding the Xanadu philodendron houseplant to yourlist. Xanadu philodendron care is simple and this larger plant makes awonderful vertical accent in the home.

What is a Xanadu Plant?

Philodendron ‘Xanadu’ (sometimes called ‘Winterbourn’) is amember of the Philodendron genus, and is a delightful and easy-to-growhouseplant. Unlike many other philodendrons,this is not a vining plant, so no support is needed.

It will form a dense clump of beautifully lobed leaves andwill tend to grow wider than taller. The Xanadu philodendron houseplant cangrow to 2 to 4 feet tall (0.6 to 1.2 m.) and up to 4-6 feet (1.2 to 1.8 m.)wide, but indoors it will probably be on the shorter end.

Growing Xanadu Philodendron Plants

Xanadu philodendron care is quite easy.

  • Light – Philodendron ‘Xanadu’ likes a little more light than most philodendrons in order to maintain its compact growth habit. Bright, indirect light will suit this plant well, and even a little direct sun, especially morning sun, will be good for this plant. If you have this plant in too dark of a location, the stems will elongate a bit too much. However, too much direct sun can cause the foliage to turn a yellowish green color.
  • Watering – Water thoroughly when you irrigate and allow excess water to drain through the drainage hole. Allow about half of the soil to dry out before watering again. Keeping this plant too wet, like any houseplant, may cause yellowing of the leaves.
  • Humidity – Philodendrons do enjoy higher humidity; however, they are very tolerant of average indoor humidity so you don’t have to worry about this too much.
  • Temperature – The ideal growing temperatures are 75-85 F. (24-29 C.) during the day and 65-70 F. (18-21 C.) for nighttime temperatures.
  • Fertilizing – Be sure to fertilize during the growing season with a fertilizer that contains all the major macro and micro-nutrients for best results. If a plant is growing very slowly and you are providing enough light, it may need more fertilizer.
  • Toxicity – These plants are poisonous to cats and dogs, so be careful where you place this plant in your home.

Philodendron Xanadu – Best Care Guide

Would you love to decorate your space with plants but have a brown thumb? Well, Philodendron Xanadu is one of the most forgiving plants.

It can thrive in different areas of your home, without requiring too much. It can be grown in a potting medium consisting of peat moss, vermiculite, and perlite or any other medium that is well-draining but can hold moisture at the same time. Put the Philodendron Xanadu in a spot with bright indirect light for the best growth. Water generously once the potting mix is about to dry out and keep this Philodendron in temperatures between 65ºF (18ºC) and 85ºF (29ºC). Fertilize once a month in Spring and Summer using a well-balanced liquid fertilizer. You can either foliar feed your plant or fertilizer when watering.

The best part is, it has an enormous spread (up to 6 feet wide), making you look like a pro gardener, even if you often forget to water it.

Here is a practical guide on how to care for a Philodendron Xanadu.

Philodendron Xanadu vs. Thaumatophyllum Xanadu

Scientific plant names may change over time, as is the case with the Xanadu plant. For many years, Xanadu was classified as a philodendron with the cultivar name of Winterbourn and the trademarked name of Xanadu (Philodendron bipinnatifidum ‘Winterbourn’ [Xanadu™]). In May 2018, however, DNA evidence prompted its reclassification, which resulted in a new scientific name – Thaumatophyllum xanadu. With scientific designations that are difficult to remember, much less to spell and pronounce, the Xanadu plant is known in the nursery trade as simply that – the Xanadu plant.

Regardless of nomenclature, the Xanadu plant is a lovely upright plant that has wide leaves with deeply cut margins. Each leaf can grow up to 18 inches long and 12 inches wide, borne on plants that generally grow from 2 to 4 feet tall with a larger spread of 4 to 6 feet.

Members of the Philodendron genus are toxic when ingested by humans or pets.

Symptoms in humans include swelling of the lips and tongue, as well as nausea and possible vomiting.

The plant is susceptible to aphids and mealybugs and may become infested with spider mite if allowed to become too dry.

Fungus gnats or mold may appear if dried leaf husks aren’t removed occasionally.

Root rot from overwatering, a bacterial disease, and leaf spot disease are all major concerns for any Philodendron plant.

Placing Xanadu where there are good air circulation and cooler overall air will help prevent disease.

Dry leaves will also help when outdoors, although this plant loves a good misting indoors to improve humidity.

As to its care as a houseplant, I will leave the advice giving on that to others who grow this as a houseplant. I grow mine in the ground.

It is a naturally vining plant and will at some point either need to be pruned back or supported by stakes or a trellis.

Thaumatophyllum spruceanum is listed as a synonym for Philodendron goeldii

May 2018 scientific research paper presented in the research journal Phytokeys

The GBIF (Global Biodiversity Information Facility) has recognized the change from subG Meconostigma to G Thaumatophyllum , it might take other online references a while to catch up. This was being looked at as early as 2002, when an article was published in Aroideana, the journal of the International Aroid Society (Vol 25) by Goncalves and Salvians on the changing concepts of the Philodendron subgenus Meconostigma.

The origin of the Xanadu is now accepted as having come from seed collected in the wild in Brazil by Dr. Thomas Croat, Julius Boos and S.J. Mayo in 1988. Not as a sport that suddenly appeared in a nursery in Australia.

I can remember when Xanadu first came onto the mass market, no one even realized it was actually a trunking plant. When the first older plants began to trunk everyone was really excited. the chatter on aroid forums was pretty wild, people saying stuff like 'Wow it DOES trunk. ' and 'Is YOURS trunking yet. ' You know, stuff only a plant geek could appreciate.
