Philodendron gigas

Natural range and habitat of Philodendron gigas

Philodendron gigas comes from Panama. In the wild, it grows in humid foothill rainforest at about 300–375 m elevation.

This is a true forest climber: in nature the vine works its way up trees, carrying larger leaves as it rises through the warm, wet vegetation.

Care for Philodendron gigas

Set up the climb early. A firm pole or plank keeps the vine steady once the leaves become large. Fasten the stem loosely and let the leaf stalks move freely.

Keep the velvet leaves out of strong direct sun. Bright indirect light supports compact growth and strong new leaves. If the plant has been in a darker place, move it toward more light in stages.

Help new leaves open smoothly. Warm conditions and 60–80% humidity suit this species well. Air movement matters too, especially around a new leaf that is still folded.

Let the surface dry before watering again. Once the upper layer of mix is dry, soak the pot thoroughly and let it drain. Use a loose, free-draining potting mix that still retains some moisture around the roots. Cooler rooms or lower light mean the plant will need water less often.

Temperature: For Philodendron gigas, maintain about 18–29 °C and prevent extended chilling below 15 °C.

Use a general houseplant fertiliser lightly while the vine is actively growing. Reduce feeding once active growth starts to slow.

Give the plant a modest increase in pot size when roots densely fill the current container. Secure or stabilise the climbing support separately if it becomes unstable.

Propagation: Take a healthy stem cutting with at least one node; keep an existing aerial root attached if one is present.

Troubleshooting Philodendron gigas

• A newly opened velvet leaf has silver scarring and black specks: Thrips may have fed while the leaf was folded. Look closely inside the newest growth and treat promptly if insects are present.
• Small pale dots spread over the dark foliage: Turn the leaves over and check for spider mites, especially if you notice fine webbing. Keep the plant apart from others and treat the mites before they spread.
• Later leaves get smaller and the gaps on the stem lengthen: The vine may be short of light or losing support. Re-secure the stem and improve the light gradually before changing fertiliser.
• The plant wilts even though the pot is still damp: Hold off on more water and make sure the drainage holes are clear. If the plant is still limp as the mix begins to dry, check the roots for damage.

Philodendron gigas is toxic to people and pets

• Keep this plant away from children, cats and dogs.
• Its leaves and stems contain insoluble calcium oxalate crystals, which can irritate the mouth, throat, skin and eyes.
• Chewing may cause burning pain, drooling, swelling, vomiting or difficulty swallowing. Contact a veterinarian or medical professional after exposure, especially if swelling or breathing problems occur.

Philodendron gigas: name and meaning

Philodendron combines Greek philein, meaning “to love,” with dendron, meaning “tree.” The epithet gigas is Greek for giant.

Heinrich Wilhelm Schott established the genus Philodendron in 1829 in Wiener Zeitschrift für Kunst, Literatur, Theater und Mode, volume 3, page 780.

Thomas Bernard Croat first described Philodendron gigas in 1997 in Annals of the Missouri Botanical Garden, volume 84, page 446.
