Philodendron Xanadu care is refreshingly boring: bright indirect light, a sparing drink once the mix is almost dry, and enough floor space for a plant that spreads sideways rather than climbing. It is the least fussy Philodendron we stock, and the one most likely to be mistaken for a small outdoor shrub. Below: light, water, pet safety and pruning.
| Care need | Recommendation |
|---|---|
| Light | Bright, indirect, filtered sunlight |
| Water | Water sparingly, soil to be almost dry |
| Pets | Not pet friendly — toxic if chewed (RSPCA Australia) |
| Difficulty | Needs a routine |
Needs a routine because it still needs a bright position and moisture checks. Drying time varies with pot size, temperature and season, so do not plan around a fixed number of weeks without water.
How much light does a Philodendron Xanadu need?
Bright, indirect, filtered sunlight. A Xanadu a metre or so back from a north or east-facing window will hold its shape and keep its leaves deeply cut, which is the whole reason to own one.
It will survive in a much darker corner, and that is where most disappointing Xanadus live. In low light the stems stretch, the mound falls open, and new leaves come out smaller with shallower lobes.
Full sun is the other extreme. Afternoon sun through glass in a Perth, Adelaide or Brisbane summer will bleach and burn the leaves, and unlike a scorched frond on a fern, a burnt Xanadu leaf is large and very visible for the year or two it stays on the plant.
How often should you water a Philodendron Xanadu?
Water sparingly, letting the soil get almost dry before the next drink. Xanadu roots are thick and hold water well, so the plant copes with being forgotten far better than it copes with sitting wet.
The seasonal swing is significant. From September to February it is actively growing and will use water reasonably quickly, particularly in a warm room. From March the growth tapers, and through winter, June to August, it needs very little water and no feeding at all.
Two habits make the difference. Water until it runs from the drainage hole rather than giving it a splash, then empty the saucer, because the roots that store water so well are the first to rot in a cold, wet pot.
Is the Philodendron Xanadu safe for cats and dogs?
No. Xanadu is toxic if chewed, along with every other Philodendron we sell. The ASPCA lists Philodendron as toxic to cats and dogs, and the reclassification of this plant to Thaumatophyllum xanadu changes the botany books rather than the chemistry: leaves and sap still cause mouth pain, drooling and vomiting.
Because Xanadu sits low and wide at floor level, it is far more accessible to a dog than a hanging plant, which is worth weighing up before you buy rather than after. Raise it on a stand, or give it a room the dog doesn’t use. RSPCA Australia keeps no per-species plant list of its own and points readers to the ASPCA database for this question, so if something does get eaten, ring your vet.
For a floor plant in a pet household, the Hurricane Fern is not known to be toxic to cats or dogs, which is a statement about its absence from the ASPCA database rather than a clearance. The Lady Palm is the firmer answer: Rhapis excelsa is listed non-toxic by the ASPCA.
Potting mix, feeding and repotting
A free-draining indoor potting mix with some bark or perlite through it suits Xanadu well. Choose width over depth when you pot it: this is a plant that grows outwards from a low crown, so a broad pot looks right and gives the roots somewhere to go. A Jardin Terrazzo Black Pot in the size up from the nursery pot is the usual pairing.
Feed through the growing season only. A diluted dose of indoor plant food every few weeks from September, tapering off around the end of March, then nothing at all from June to August. Feeding a dormant plant just leaves salts in the mix.
Repot in spring, September to November, once roots start showing at the drainage holes. Wear gloves if you are dividing or cutting it, because Philodendron sap irritates skin.
Can you grow Philodendron Xanadu outside in Australia?
Yes, and this is the one Philodendron we would actively suggest it for. In the subtropics it gets used as a landscaping plant as often as a houseplant.
The conditions are shade or part shade, shelter from wind, and no frost. A covered verandah, a courtyard with morning sun only, or a bed under established trees all work well in Brisbane, the Gold Coast and coastal New South Wales.
South of about Sydney it gets harder. Melbourne, Canberra and Hobart winters bring frosts that damage the leaves badly, so keep it in a pot you can move under cover, or grow it indoors and let it summer outside in the shade.
Common Philodendron Xanadu problems
- Yellowing lower leaves. Usually too much water, and in winter it is almost always too much water. Let the mix dry out properly and check the pot is draining.
- Brown, crisp leaf edges. Either long dry spells between drinks or a spot in the airflow of a heater or air-conditioner. Water a little sooner and move it out of the draught.
- A floppy, open mound with small new leaves. Not enough light. Move it brighter and remove the longest stretched stems at the base to encourage a tighter shape.
Where our Philodendron Xanadus come from
Xanadu is dispatched from our Queensland nursery in its nursery pot, with natural variation between individual plants.
Every plant arrives with a printed care card, packed in low-waste, plastic-free packaging, and backed by our 30-day plant guarantee. See our returns and plant guarantee policy for details. Allow packing time plus around 3–5 business days of courier transit to most metro areas.

Philodendron Xanadu care FAQs
Is Philodendron Xanadu the same as Philodendron Selloum?
They are relatives, not the same plant. Both have been moved out of Philodendron into the genus Thaumatophyllum, and both have deeply cut leaves, but Selloum grows into a large plant with a thick trunk over time while Xanadu stays a compact, self-contained mound. For an indoor pot or a small courtyard, Xanadu is the manageable one.
Does Philodendron Xanadu need a moss pole or stake?
No. Xanadu is self-heading, which means it grows in a rosette from a central crown instead of vining, so there is nothing to train up a totem. If your plant is leaning or splaying, the fix is more light rather than a stake, though a heavy pot helps a large specimen stay put.
Why aren’t my Philodendron Xanadu’s new leaves splitting?
Young leaves on a young plant are naturally less divided, and the deep lobes develop as the plant matures. Light is the other factor: a Xanadu in a dim corner keeps producing juvenile-looking leaves indefinitely. Move it into bright indirect light, feed it through spring and summer, and the lobes deepen on each new flush.
