Philodendron squamiferum

The Guianas and adjoining Amazonian Brazil

Philodendron squamiferum grows in wet forest in French Guiana, Suriname and northern Brazil. It climbs trees with roots that attach to the bark. Eduard Poeppig named the species in 1845.

Care for supported climbing aroids

• Light: Five-lobed mature leaves develop most reliably when the vine climbs in bright indirect light. Avoid abrupt direct sun.
• Water: When the upper mix starts drying, water thoroughly and let excess run out of the container.
• Humidity and airflow: Keep humidity moderate to high so new leaves can unfold smoothly. Airflow prevents moisture from lingering among the bristly red leaf stalks.
• Substrate: A porous aroid mix should hold moisture while air moves freely around the roots.
• Feeding: Use a moderate feed during active growth and reduce the dose when new growth slows.

When Philodendron squamiferum needs attention

• Juvenile leaves: Young or recently propagated plants may carry entire heart-shaped leaves before the five-lobed mature form develops. Progression with climbing is normal and should be judged across several leaves.
• Red bristles and scales: Dense red bristles and scales on the leaf stalks and stem are part of the plant. They stay attached and do not produce honeydew; removable waxy bodies or sticky sooty growth indicate insects.
• Hidden insects: Mealybugs, scale and thrips can shelter between the bristles. Look for cottony wax, black specks or moving pests and wipe away visible colonies. Direct a suitable indoor-use control between the bristles without scraping off the plant's own red structures.
• Wet decay around stalks: Bristles can hold moisture and old sheath material close to the stem. Keep air moving, remove only loose decaying debris and prevent water from remaining trapped.
• Uneven lobes above red bristles: One-sided expansion, scraped silver scars and black droppings point towards thrips feeding in a rolled leaf. Do not force the leaf open; separate the vine and use an indoor-plant control that lists thrips, repeating it only as directed.
• Yellowing below a bristled stem: Yellowing accompanied by slow drainage, soft roots or odour points below the bristled stem to root damage. Remove collapsed roots, renew the open mix and keep the climbing stem clear of the wet substrate.

Philodendron squamiferum is toxic to pets

• Philodendron squamiferum is toxic to cats and dogs.
• Chewing releases insoluble calcium oxalate crystals, which can cause immediate mouth pain, drooling and difficulty swallowing.
• Contact a veterinarian promptly after suspected chewing, especially if swelling or breathing problems occur.

Love and tree in Greek; squamiferum means scale-bearing

Squamiferum means scale-bearing, referring to scaly leaf stalks. Philodendron combines Greek philein, meaning “to love,” with dendron, meaning “tree.”
