Philodendron sodiroi

Origin and background of Philodendron sodiroi

Philodendron sodiroi is native to Colombia, where it grows as a climber in the wet tropical biome. N. E. Brown formally published the species in 1883.

Care for Philodendron sodiroi

Climbing support and light: Start the stem on a pole or plank while it is easy to position and keep active nodes close to the surface. Give bright indirect light; if several new leaves become smaller and the spaces between nodes lengthen, increase usable light gradually after checking root health.

Water and substrate: Use a loose, well-drained mix that still holds some moisture. Let the upper layer dry slightly, water thoroughly and allow the pot to drain fully.

Humidity: Keep the air from becoming extremely dry while the broad silver-marked leaves expand. If heating repeatedly causes crisp margins despite even root moisture, use a humidifier nearby and maintain light airflow around the foliage.

Temperature: Keep the plant above 15 °C and away from cold draughts, hot radiators and abrupt temperature swings.

Feeding and repotting: Feed lightly during active climbing growth. Repot when roots become crowded or the mix compacts, moving the plant and support together when aerial roots are firmly attached.

Troubleshooting Philodendron sodiroi

• New leaves become progressively smaller and internodes lengthen: Check usable light, root condition and whether the stem is still climbing securely. Correct the weakest factor before adding more fertiliser.
• Tan or bleached patches appear after stronger sun: Move the plant back into filtered light and acclimatise any future increase gradually. Damaged tissue will remain marked, but new leaves should emerge cleanly.
• Leaf edges brown gradually: Check for repeated dry-outs, fertiliser salt buildup, root damage and very dry heated air. Flush excess salts with plain water if needed and let the pot drain fully. See our brown leaf tips guide for further diagnosis.
• New growth is distorted with silvered scars and black specks: Isolate the plant and inspect the emerging leaf for thrips. If present, remove accessible pests and use a houseplant treatment labelled for thrips, following the label for coverage and repeat applications.

Philodendron sodiroi 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 sodiroi mean, and who first published it?

Philodendron combines Greek philein, meaning “to love,” with dendron, meaning “tree.” Sodiroi honours Luis Sodiro, an Italian Jesuit priest and botanist who worked in Ecuador.

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

Nicholas Edward Brown first described Philodendron sodiroi in 1883 in Gardeners’ Chronicle, new series, volume 19, page 510.
