Philodendron gloriosum

Along the ground in Colombia’s forests

In Colombia, the stem of Philodendron gloriosum grows horizontally along the floor of wet Andean and Orinoco-region forests at roughly 350–700 m.

Édouard André published the species in 1876. The IUCN assessed it as Vulnerable in 2021 because of its restricted wild range and continuing habitat decline.

Care for creeping aroid roots and foliage

• Propagation: For division, cut the rhizome so every section retains a living bud or growing point, ideally with established roots.
• Substrate: The roots need an airy mix that stays evenly moist. Rest the rhizome at or just above the surface.
• Light: Place it in bright filtered light. Direct midday sun can mark the soft surface of its broad velvet leaves.
• Watering: Water as the upper layer dries while the mix around the shallow feeder roots remains faintly moist, keeping runoff away from the exposed creeping rhizome.
• Humidity and airflow: Emerging velvet leaves are less likely to stick in moderate to high humidity. Maintain airflow around both the foliage and the exposed rhizome.
• Space: Its rhizome advances sideways across the soil, so use a wide or rectangular container and guide the tip into open space. It does not need a vertical pole.

Philodendron gloriosum: rhizome position, velvet and leaf damage

• Tip at the pot edge: A healthy growing point can stall when the horizontal stem reaches the wall of the container. Guide it into open mix or move the plant to a wider pot; extra fertiliser will not solve a lack of space.
• Veins and young leaf margins: Pale veins and, in some plants, pinkish young margins are normal. Irregular feathering or mosaic that crosses the vein pattern, especially with repeated distortion, warrants isolation and testing.
• Soft rhizome: Wet mix covering the horizontal stem can make it soften, darken and develop an odour. Lift healthy tissue to the surface, remove rotten portions with a clean tool and restore an airy root zone.
• Marks across the velvet blade: Dust and mineral residue sit on the surface, while mites create many pale damaged points within the leaf. Clean gently with a dry soft cloth and inspect the lower surface with magnification before treating.
• Injury inside rolled growth: Thrips often feed inside rolled growth, leaving silver scars, black specks and uneven expansion. Move the plant away from other plants, inspect every emerging leaf and use a thrips-labelled product at the repeat interval given on its label.
• Crisp margins on broad leaves: Dry root pockets, accumulated salts, direct sun or root loss can all produce crisp edges. Check the pot and rhizome first, remove the exposure and flush the mix when fertiliser residue is likely.

Philodendron gloriosum 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.

What does Philodendron gloriosum mean, and who first published it?

Philodendron combines Greek philein, meaning “to love,” with dendron, meaning “tree.” Gloriosum comes from Latin and means glorious or splendid.

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

Édouard-François André first described Philodendron gloriosum in 1876 in L’Illustration Horticole, volume 23, page 194.
