Philodendron ushanum – glossy foliage and heart-lobed leaves


Philodendron ushanum is a rare species known for its dramatic, glossy green leaves shaped like a deep-lobed heart. First described by Croat and Moonen, this collector’s plant comes from the tropical forests of South America, where it climbs trees with ease. The leathery sheen and defined lobes give it a bold, sculptural presence unlike any common Philodendron. With time, the foliage matures into broad, deeply sinuate blades, adding texture and movement to your collection.


Visual appeal and traits of Philodendron ushanum


This species stands out for its thick, glossy leaves with pronounced posterior lobes. New leaves often emerge lighter in color and gradually darken as they mature. The plant has a climbing growth habit and produces elongated petioles with subtle striations. Given the right support and conditions, Philodendron ushanum becomes a lush, upright focal point over time.

What to know about Philodendron ushanum’s origin and growth


Philodendron ushanum belongs to the Araceae family and was officially described by Thomas B. Croat and Jean M. Moonen. It originates from tropical South America, where it grows as a hemiepiphyte in humid forests. In cultivation, it thrives in warm, bright conditions with high humidity. Mature plants can reach over 1.5 meters in height when staked. Like most aroids, it has a perennial lifecycle and moderate to fast growth under ideal care. This species is considered toxic due to calcium oxalate crystals—keep it away from pets and small children.

Philodendron ushanum care guide for indoor growers


Light preferences
Bright, filtered light works best. Avoid intense direct sun, which can scorch the glossy leaves. It tolerates medium light but grows faster with higher light levels.
Watering needs
Let the top few centimeters of soil dry out before watering again. This plant prefers consistent moisture without staying soggy. Drainage is essential.
Humidity and temperature
Keep humidity above 60% if possible. Warm temperatures between 20–28 °C encourage steady growth. Avoid cold drafts.
Soil and repotting
Use a loose, aroid-style substrate rich in bark, perlite, and coco coir. Repot when root-bound or when the mix compacts too much.
Fertilization tips
Fertilize monthly with a balanced liquid fertilizer. Avoid overfeeding, especially in low light or cooler months.
Propagation tips
Stem cuttings root well in water, moss, or semi-hydroponic setups. Choose nodes with aerial roots for the best success.
Climbing support and pruning
Provide a moss pole or stake to support its natural climbing habit. Prune older or damaged leaves to maintain shape.
Hydroponic adaptation
Philodendron ushanum can be adapted to semi-hydroponics with inert substrates. Monitor root health during the transition.


Issues and pests affecting Philodendron ushanum



 
Yellow leaves: Usually from overwatering or poor drainage.
 
Brown tips: Often caused by low humidity or underwatering.
 
Pest risks: Mealybugs, spider mites, and scale can occur—inspect regularly and isolate new plants.
 
Root rot: Avoid compact soil and use a well-aerated mix.


Care extras for Philodendron ushanum


This species appreciates consistent conditions. Avoid abrupt environmental changes. Supporting the plant early helps it form a more upright structure with larger leaves. Clean the glossy foliage regularly to encourage healthy photosynthesis.


Etymology: name origin of Philodendron ushanum


The genus name Philodendron is derived from Greek “philo” (love) and “dendron” (tree), referencing its tree-loving growth habit. The species epithet “ushanum” honors an unknown namesake (possibly a locality or collector) but was formally described by botanists Croat and Moonen in the early 2000s.


FAQs about Philodendron ushanum



 
How fast does Philodendron ushanum grow?
