Epipremnum aureum

Epipremnum aureum is a tropical climbing aroid with flexible vines, glossy heart-shaped leaves, and aerial roots that anchor to bark, moss poles, trellises, or other textured supports. In indoor pots it usually keeps its juvenile foliage, with green leaves marked by yellow to cream streaking, while supported mature plants can eventually produce larger, thicker leaves with a more divided outline.

This species is often called golden pothos, devil’s ivy, or simply pothos in everyday plant trade, although Pothos is also a separate botanical genus. The plant sold as Epipremnum aureum belongs in Araceae and grows naturally as a wet-tropical climber from Mo‘orea in the Society Islands, where its stems use aerial roots to move upward through humid forest structure.

Golden pothos traits at a glance

• Evergreen aroid vine with trailing or climbing stems.
• Glossy juvenile leaves with a broad heart-shaped base.
• Green foliage with yellow to cream marbling and streaks.
• Aerial roots that attach readily to moss poles, bark boards, or rough supports.
• Node-based stems that can trail, climb, branch, or root from cuttings in indoor pots.

How this species climbs and fills a pot

Epipremnum aureum grows from nodes spaced along flexible stems. Each node can produce a leaf, an aerial root, and a new shoot, which makes the plant easy to prune, root, and train. In a hanging pot the stems cascade and create a loose curtain of foliage; on a vertical support the same plant directs growth upward and can develop larger leaves over time.

As a wet-tropical climber, Epipremnum aureum needs air as well as moisture around the roots. A loose substrate and a pot with drainage are essential. Warmth keeps growth active, while consistent bright indirect light helps leaves expand evenly and protects the glossy surface from scorch.

Care for strong vines and airy roots

• Light: Place in bright indirect light or soft filtered light. The plant tolerates medium light, but very dim placement slows internode growth and can make vines thinner.
• Water: Water when the upper 20–30% of the potting mix has dried. The stems recover well from slight drying, while saturated mix can weaken the fine roots.
• Substrate: Use an airy aroid mix with bark, perlite, coco chips, or similar coarse material so water drains quickly and oxygen reaches the root zone.
• Temperature: Keep between 18–28 °C for regular growth. Protect from cold windowsills, winter draughts, and temperatures below about 12–15 °C.
• Humidity: Average indoor humidity is usually tolerated. Higher humidity helps new leaves expand more smoothly, especially on climbing stems.
• Feeding: Feed lightly during active growth with a balanced fertiliser. Reduce feeding in winter or under low light.
• Support and pruning: Let vines trail, or guide them onto a moss pole for stronger upward growth. Prune above a node to encourage branching and root cuttings from healthy stem pieces.

Problems that show up on older vines

• Yellow lower leaves: Check whether the potting mix has stayed wet for too long. Let the mix dry further and improve drainage before watering again.
• Brown, dry leaf edges: Look for irregular watering, strong sun, salt build-up, or dry heat near radiators. Flush the mix occasionally and move the plant away from hot air.
• Long bare sections: Increase light gradually and prune leggy stems back to active nodes so new shoots can fill in closer to the pot.
• Soft stems near the base: Inspect the roots and lower nodes. Soft, dark tissue usually points to overwatering, cold wet substrate, or poor aeration.
• Sticky leaves or speckling: Check the undersides and stem joints for scale, mealybugs, thrips, or mites, then isolate and treat early.

Safety around pets and children

Epipremnum aureum contains insoluble calcium oxalate crystals. Chewed leaves or stems can irritate the mouth, lips, tongue, and digestive tract, so keep the plant away from pets and small children. Wear gloves if your skin reacts easily to aroid sap.

Botanical name background

The genus name Epipremnum comes from Greek roots meaning “upon” and “trunk,” a reference to its climbing habit. The species epithet aureum means “golden,” matching the yellow-gold variegation associated with the classic cultivated plant.
