Epipremnum aureum 'Glacier' (Glacier Pothos)
Epipremnum aureum 'Glacier' (Glacier Pothos)
Introduction
Epipremnum aureum 'Glacier' (Glacier Pothos) is a cool-toned variegated pothos cultivar with smaller leaves patterned in grey-green, silver, and white. More compact and slower-growing than standard pothos, it suits shelves and hanging baskets.
Epipremnum aureum 'Glacier' is a cultivar of the common pothos in the family Araceae. The leaves are smaller than most pothos cultivars (5–10 cm), with a cool grey-green background overlaid with irregular white, cream, and silver-grey patches. The variegation gives a frosted, icy appearance — hence 'Glacier'.

History & Cultural Significance
'Glacier' is a modern horticultural cultivar selected from the *Epipremnum aureum* species. Pothos have been popular houseplants since at least the 1950s due to their extreme adaptability. The cool-toned variegated cultivars gained popularity in the 2010s as collector interest in distinct pothos forms grew.
About Trailing & Vining
Trailing and vining houseplants represent diverse families united by their climbing or cascading growth habit — an adaptation for reaching canopy light in dense tropical forests. Pothos (Epipremnum aureum) and Philodendron are aroids that produce aerial roots to grip tree bark; their juvenile leaves often look completely different from mature canopy-level foliage (heteroblasty). Scindapsus produces silvery leaf patterns through specialized reflective cells (trichomes) that may assist in capturing light in deep shade. String-of-hearts (Ceropegia woodii) is a tuberous African vine that stores water in aerial tubers along its stems — a survival strategy for seasonal drought.

*Epipremnum aureum* (family Araceae) is native to the Solomon Islands. 'Glacier' is a cultivated variety distinguished by its cool-toned variegation and more compact growth habit compared to standard *E. aureum* cultivars.
Growth Timeline
Slower-growing than standard *E. aureum*. Stems extend 5–15 cm per month in growing season. A full hanging basket develops within 12–18 months under good conditions.
Light Requirements
Bright indirect light is required to maintain the white variegation. In low light, new leaves emerge with less white and more grey-green. Avoid direct sun which scorches the pale variegated sections. An east-facing window is ideal.
Group Light Guide
Pothos, Philodendron, and Scindapsus adapt to low light but grow fastest in medium to bright indirect light. Variegation is maintained better in brighter conditions. They make ideal plants for shelves and hanging baskets away from windows.
Watering
Water when the top 3 cm of soil is dry. The smaller leaves mean less water storage capacity — check more frequently than standard pothos. Use room-temperature water. Overwatering causes yellowing; underwatering causes wilting and leaf curl.
Group Watering Guide
Pothos and Philodendron are forgiving with watering. Allow the top 2 inches to dry completely. They show their thirst by slightly drooping leaves. These plants recover quickly from underwatering but suffer more from overwatering. Reduce winter watering by half.
Humidity & Temperature
Tolerates average household humidity (40–60%). Prefers 18–26 °C. Variegated leaves are somewhat more cold-sensitive than all-green types — keep above 15 °C.
Group Humidity & Temperature Guide
Pothos, Philodendron, and Scindapsus are adaptable to a wide humidity range (30–60% RH). Higher humidity promotes larger leaves and faster growth. Satin pothos (Scindapsus pictus) and string of hearts prefer slightly drier conditions than tropical philodendrons. Temperatures of 15–30°C suit these plants well; most tolerate brief drops to 10°C without damage. Trailing plants hung from ceilings tend to experience lower humidity and higher temperatures — monitor for curling or crispy leaf edges, which indicate the air is too dry at that elevation.
Soil & Potting
Well-draining mix: quality potting soil + 25% perlite. The slower growth rate means less frequent repotting — every 2–3 years or when rootbound. Avoid overpotting which encourages root rot.
Group Soil Recipes
Pothos and Philodendron thrive in loose, rich mix: 50% potting mix, 30% perlite, 20% coco coir or orchid bark. These fast growers need repotting every 1–2 years. They tolerate a wide range of soil types. pH 6.0–6.5. Aroid mixes work excellently.
| Repotting frequency | every 2–3 years (spring) |
| Pot size up | 2–3 cm larger diameter than current |
| Growth rate | moderate |
| Drainage | Essential — always use pots with drainage holes |
Fertilizing
Feed every 4–6 weeks in spring and summer with a balanced fertiliser at half strength. The slower growth rate means less fertiliser is needed compared to standard pothos. No feeding in winter.
Group Fertilizing Guide
Fast-growing trailing plants like pothos and philodendron benefit from regular feeding every 2–3 weeks with balanced liquid fertilizer during the growing season. Their rapid growth depletes soil nutrients quickly. For water-propagated cuttings, add a few drops of liquid fertilizer to the water monthly. Slow down feeding in autumn as vine elongation slows naturally.
| Spring (Mar–May) | Resume feeding every 2–3 weeks with balanced liquid fertilizer at half strength |
| Summer (Jun–Aug) | Peak feeding period — every 2–3 weeks at full dilution rate |
| Autumn (Sep–Nov) | Reduce to monthly, then stop by late October |
| Winter (Dec–Feb) | No fertilizer — plant is in rest phase, roots cannot absorb nutrients efficiently |
Propagation
Stem cuttings with 2–3 nodes root readily in water or moist perlite within 3–4 weeks. Each cutting should include at least one variegated leaf. The variegation pattern is maintained vegetatively but may vary in intensity.
Group Propagation Guide
Trailing and vining plants are among the easiest houseplants to propagate. Pothos and Philodendron root in plain water within 1–2 weeks from single-node stem cuttings. Cut just below a node, remove the lowest leaf, and place in a clean glass jar. Change water weekly. Transfer to soil when roots are 5–8 cm long. Scindapsus roots more slowly (3–4 weeks). For bushier plants, root 4–5 cuttings together in one pot. String of hearts (Ceropegia) propagates from tuber cuttings, butterfly method (leaf pair pressed into soil), or water propagation of stem cuttings.
| Method | Technique | Best timing | Success rate |
|---|---|---|---|
| Stem Cuttings | Cut below a node with 2–3 leaves. Remove lower leaves, dip in rooting hormone, place in moist perlite or water. Roots in 2–6 weeks. | Spring–Summer | High (80–90%) |
| Water Propagation | Place cutting with node submerged in clean water. Change water weekly. Transfer to soil when roots reach 3–5 cm. | Any season | High (80%) |
Pruning & Maintenance
Trim to maintain desired length. Pinch growing tips to encourage branching. Remove any all-green shoots (reversion) immediately to prevent them from outcompeting the variegated growth.
Group Pruning Guide
Regular pruning is essential for trailing plants to maintain density. Cut leggy, bare vines back to 2–3 nodes from the soil — new growth sprouts from dormant buds at each node. Root the cuttings and replant them in the same pot for a fuller appearance. For climbing specimens, redirect growth and secure to moss pole with soft ties. Remove any reverted (all-green) growth on variegated cultivars immediately as reverted sections grow faster and can overtake variegated portions.
| Pruning frequency | as needed during the growing season |
| Best time to prune | Early spring before new growth flush |
| Leaf cleaning | Monthly — wipe with damp cloth to clear stomata |
| Tool sterilization | 70% isopropyl alcohol between cuts |
| Growth rate | moderate |
Common Problems
Reversion to all-green: normal in very low light — increase light levels. Yellowing leaves: overwatering. Slow or no growth: normal in winter; in growing season indicates insufficient light or nutrients.
Troubleshooting Guide
Pale, minimal variegation: needs more light. Yellow leaves: overwatering. Brown tips: low humidity or fluoride in tap water. Leggy with large gaps between leaves: insufficient light.
Pest & Disease Guide
Mealybugs hide in leaf axils — treat with isopropyl alcohol. Spider mites in dry conditions — increase humidity and treat with neem oil. Fungus gnats from overly moist soil — allow to dry more between waterings.
Group Pest Profile
Spider mites are common on pothos and philodendron in dry air — check leaf undersides for stippling and webbing. Mealybugs cluster at nodes and in leaf sheaths. Scale insects attach to stems, especially on woody, mature sections. The dense, cascading growth habit of trailing plants makes early detection difficult — inspect thoroughly during watering, pulling apart the vine curtain. Fungus gnats are common in moist soil. Root rot (Pythium, Phytophthora) is a bigger threat than pests — mushy black roots, yellowing lower leaves, and foul soil odour indicate waterlogged conditions requiring immediate repotting.
| Pest | Identification | Treatment |
|---|---|---|
| Spider mites | Fine webbing on leaf undersides, stippled yellowing leaves | Shower blast, neem oil spray, predatory mites (Phytoseiulus persimilis) |
| Mealybugs | White cottony masses in leaf axils and stem joints | Isopropyl alcohol on cotton swab, insecticidal soap, systemic imidacloprid |
| Scale insects | Brown or tan bumps on stems and leaf midribs | Manual removal, horticultural oil, systemic treatment for heavy infestation |
| Fungus gnats | Small black flies around soil, larvae in wet substrate | Allow soil to dry between waterings, BTi (mosquito dunks), yellow sticky traps |
| Thrips | Silver streaks on leaves, black frass dots | Blue sticky traps, spinosad spray, systemic treatment |
Pet & Child Safety
TOXIC to cats and dogs — *Epipremnum aureum* contains insoluble calcium oxalate crystals. Ingestion causes immediate oral pain, drooling, vomiting, and swelling of the mouth and throat. Keep out of reach of all pets.
Safety Precautions
| Placement | High shelves, hanging baskets, or rooms inaccessible to pets |
| Fallen leaves | Remove promptly — dried plant material retains toxicity |
| Water runoff | Drain saucers after watering — some toxins leach into standing water |

Display & Styling
Glacier Pothos excels in hanging baskets or on high shelves where its cool-toned, compact trails can cascade. The silver and white variegation pairs beautifully with dark-coloured pots. Excellent in minimalist, Scandi-style interiors.
Group Display Ideas
Let pothos and philodendron trail naturally from high shelves, hang in baskets, or climb moss poles. They look beautiful in macrame hangers near windows. Cascading vines soften architectural edges and add life to bookshelves. Train climbing varieties on trellises or poles.
| Best position | hanging basket or high shelf |
| Light zone | medium to bright indirect |
| Humidity needs | tolerant |
| Indoor height | 20-30 cm |
Companion Planting Indoors
The cool silver-grey tones complement *Tradescantia zebrina*, *Scindapsus pictus*, and silver-leaved *Peperomia* species. Contrast with warm-toned plants like golden pothos or copper-leaved begonias for visual interest.
Seasonal Care Calendar
Spring/Summer: active growth — water and feed regularly. Autumn/Winter: growth slows — reduce watering and cease fertilising. The variegation may become less pronounced in winter light.
Group Seasonal Guide
Spring: Prune leggy vines to encourage bushier growth; root the cuttings. Repot if root-bound. Resume regular fertilizing. Summer: Fastest growth period — trailing plants can grow 30+ cm per month. Increase watering. Pin aerial roots into soil for self-layering. Autumn: Reduce feeding. Prune back excessive growth before winter. Clean leaves of dust. Winter: Growth slows significantly. Reduce watering — allow soil to dry more between waterings. Variegated varieties may produce more green (reverted) growth in low winter light; prune reverted sections in spring.
| Season | Watering | Feeding | Key tasks |
|---|---|---|---|
| Spring | Increase gradually | Resume every 2–3 weeks | Repot if needed, prune dead growth, check for overwintering pests |
| Summer | Most frequent | Peak feeding | Monitor for pests, rotate for even growth, increase humidity |
| Autumn | Reduce gradually | Taper off by October | Move away from cold windows, reduce watering frequency |
| Winter | Minimal | None | Maintain min. 10°C, increase light if possible, watch for dry air from heating |
Frequently Asked Questions
How often should I water my Glacier Pothos?
Water Glacier Pothos moderate - let top dry. During the growing season (spring/summer) this is typically every 7-10 days; in winter reduce to every 14-21 days. Always check the soil moisture before watering — insert your finger 2 inches into the soil; if it feels dry, it's time to water.
What light does Glacier Pothos need?
Glacier Pothos requires medium to bright indirect. Avoid harsh direct afternoon sun which can scorch leaves. If you notice pale, washed-out leaves, the plant may be getting too much sun; leggy, sparse growth indicates insufficient light.
Is Glacier Pothos safe for cats and dogs?
No. Glacier Pothos is toxic to cats and dogs. Keep it out of reach of pets and children. If ingestion is suspected, contact ASPCA Animal Poison Control at 888-426-4435 immediately.
Why are the leaves of my Glacier Pothos turning yellow?
Yellow leaves on Glacier Pothos most commonly indicate overwatering. Check that the soil is not constantly wet and that the pot has proper drainage. Other causes include insufficient light, nutrient deficiency, or natural aging of lower leaves. Assess all factors and adjust care accordingly.
Why do my Glacier Pothos have brown leaf tips?
Brown leaf tips on Glacier Pothos are usually caused by low humidity, fluoride or chlorine in tap water, or inconsistent watering. Try using filtered or rainwater, increasing humidity with a pebble tray or humidifier, and establishing a more consistent watering routine.
How do I propagate Glacier Pothos?
Glacier Pothos is most easily propagated by stem cuttings. Take cuttings in spring or early summer during the active growing season for the best results. Ensure your cutting has at least one node, use a rooting hormone for faster root development, and provide warm, humid conditions.
What humidity does Glacier Pothos prefer?
Glacier Pothos prefers tolerant relative humidity. If your home is dry, especially in winter with central heating, use a pebble tray filled with water, group plants together, or use a small humidifier nearby. Avoid misting directly on leaves as it can cause fungal issues.
Is Glacier Pothos a good plant for beginners?
Yes! Glacier Pothos is considered beginner-friendly. It is forgiving of occasional missed waterings and adapts to typical home conditions.
When and how should I repot Glacier Pothos?
Repot Glacier Pothos in spring when you see roots emerging from drainage holes, the plant drying out very quickly, or noticeably stunted growth. Choose a pot only 2 inches larger in diameter than the current one. Use fresh potting mix appropriate for the species and water thoroughly after repotting.
What are the most common pests on Glacier Pothos?
The most common pests on Glacier Pothos are spider mites (look for fine webbing and stippled leaves), mealybugs (white cottony clusters in leaf joints), and scale insects (brown bumps on stems). Fungus gnats can be a problem in overwatered plants. Treat infestations early with neem oil, insecticidal soap, or isopropyl alcohol.
