Philodendron Verrucosum
Philodendron verrucosum · the Velvet-Leaf Philodendron
It climbs the trunks of cool, misty cloud forests in Central and South America, a velvet-leaved aroid with hairy, warty leaf stalks. The leaf is deep emerald to near-black, lit by pale veins, with a red flush beneath.

Where it's from
Cloud forests of Central and South America
Cloud-forest climber
From Costa Rica, Panama, Colombia, Ecuador and Peru, often above 500 m where the air stays misty.
Outdoors: zones 11–12
Frost-free wet tropics only. It resents heat and dry air as much as cold.
Not invasive
A demanding cloud-forest specialist, the opposite of a weedy escapee.
Named for its warts
Verrucosum is Latin for warty. The name was given not for the famous velvet leaf but for the bristly, wart-covered leaf stalks. So the plant collectors chase for its velvet is officially named after its warts.
Warts, not velvet
The name points to the hairy, bumpy petioles, not the leaf.
A velvet sheen
The leaf is deep green with a soft velvet finish and pale, contrasting veins.
Red beneath
The undersides are flushed a deep maroon red.
How to keep it
LightBright, indirect
No direct sun, which scorches the velvet leaf. Enough light keeps growth compact and the veins vivid.
WaterKeep lightly moist
Let the top inch or two dry. Very prone to root rot if soggy, so drainage is critical.
HumidityVery high, 70–90%A cloud-forest plant. It browns below 50–60%. This is the make-or-break factor.
Temperature18–29°CWarm but not hot. Happiest above 20°C, with no cold drafts and no frost.
SoilChunky, airy aroid mixBark, perlite and sphagnum. Many growers run it in near-pure sphagnum for moisture plus air.
FeedingGrowing seasonA dilute balanced feed through the growing season, easing off in winter.
DifficultyHardAdvanced. It sulks and stalls unless humidity and warmth are dialled in.
With petsToxicInsoluble calcium oxalate crystals. Oral burning, swelling, drooling and vomiting if chewed.
PropagationCutting at a nodeA node cutting roots in moist sphagnum or a humid box. The trade scales it by tissue culture.
RepottingEvery 2 yearsInfrequently, and gently. It dislikes root disturbance.
What the data says
What it costs
A collector plant, not a commodity. Even the plain form trades at a premium because it is fussy.
$40–180+
Named forms like 'Incensi' and locality plants sit higher. Tissue culture has eased supply but not the price.
IUCN · Not assessed
In the wild
The collector's paradox: pricey because it comes from a fragile, shrinking habitat.
It is fussy and expensive precisely because it comes from cool, narrow-elevation cloud forest that is being cleared. Yet it is now mass-propagated by tissue culture and thriving in living rooms. Vanishing forest at home, multiplying on shelves abroad. Note: it is not CITES-listed, despite shops that claim otherwise.
When it sulks
Brown, crispy edgesHumidity too low. The single most common verrucosum complaint.
Yellow leaves, mushy stemOverwatering and poor drainage leading to root rot.
Fungal leaf spotsWet foliage and stagnant air. Improve airflow.
Faded colour, leggyToo little light. Find bright indirect light.
PestsSpider mites love the dry air it hates. Also thrips, mealybugs and scale.
