Cultivated cultivar — derived from Philodendron erubescens, native to Colombia, Panama, Costa Rica and other Central American/northern South American forests
How to identify it
Growth habit. Vining/climbing aroid in the wild — clambers up tree trunks via thick aerial roots. Indoors trained on a moss pole for vertical growth, or allowed to trail from a hanging pot. Each leaf emerges from a single node along the stem; mature stems become woody and produce thick aerial roots from each node. Without a support, the stem becomes long and straggly with progressively smaller leaves.
Leaves. Glossy dark green leaves with deep burgundy-red undersides and a burgundy flush along the midrib, on petioles 10–20 cm long. The diagnostic feature is the chimeric variegation: irregular bright hot-pink patches, sectors, half-leaves, or speckles distributed unpredictably across the blade. Variegation is highly variable: some leaves are nearly entirely pink (rare and weak), some are 50/50 split, some have small pink flecks, and some have no pink at all. New leaves emerge with bright pink flush and darken with age.
Flowers. Aroid spathe-and-spadix; rare indoors. The species' wild flower has a deep red-purple spathe.
- Glossy dark burgundy-green leaves with irregular bright hot-pink chimeric variegation.
- Leaf undersides are deep burgundy-red.
- Vining habit with thick aerial roots from each node.
- Variegation is chimeric and visibly inconsistent leaf-to-leaf.
- New leaves emerge with bright pink flush.
Commonly confused with
Pink Congo philodendron
THE INFAMOUS SCAM. Pink Congo plants are plain Philodendron 'Congo' that have been chemically treated (with ethylene injections) to force temporary pink coloration in new leaves. The pink fades to plain green within 3–9 months and never returns. There is no genuine 'Pink Congo' cultivar — every plant sold under that name is fake. Tell from a real Pink Princess by: (1) Pink Congo has solid uniform pink across whole leaves, never patchy chimeric variegation; (2) Pink Congo has no burgundy-red on leaf undersides; (3) New growth on Pink Congo emerges all-green after the chemical wears off. Never buy 'Pink Congo'.
Strawberry Shake philodendron
Distinct cultivar with similar pink-and-green chimeric variegation but on lighter green leaves with a yellow-green base rather than dark burgundy. Even rarer and pricier than Pink Princess.
Pink Princess Marble
Cultivar variant of Pink Princess with finer marbled / speckled pink rather than large patches. Genuine cultivar, not a scam, but commands a premium.
Burle Marx Fantasy philodendron
Solid green leaves with crisp silver-white venation. No pink at all. Different visual identity but same vining habit and care.
Care
Light
Bright indirect — minimum 12,000 lux to maintain pink variegation.
Pink variegation is highly light-dependent. Below 10,000 lux the plant produces fewer pink sections per leaf and is more prone to reversion to plain green; below 6,000 lux variegation collapses entirely. Place 0.5–1.5 m back from a south or west window with a sheer curtain, or directly in front of an east window. Direct midday summer sun bleaches the pink to pale orange and scorches leaf edges. In Nordic winters most apartments fall below the maintenance threshold for variegation; a full-spectrum LED at 12 hours/day from October through March is effectively required for collectors who care about pink retention.
Seasonal: Winter grow lights are non-negotiable for keeping the variegation crisp.
Water
When the top 2–3 cm of soil is dry — every 7–10 days.
Water thoroughly until water runs from the drainage holes, then empty the saucer. Allow the top 2–3 cm to dry between waterings. Fully pink leaves (no green) cannot photosynthesise and are weak — they often crisp at the edges first when the plant is even slightly under- or over-watered. Use room-temperature filtered or rainwater.
Seasonal: Reduce frequency to every 10–14 days in winter.
Soil
Chunky aroid mix — equal parts potting soil, perlite, and orchid bark.
Use a chunky aroid mix: 1:1:1 potting soil, coarse perlite, and orchid bark. The mix should drain freely but retain moisture between waterings. Many growers use a more aggressive 50% inorganic blend (pumice + perlite + bark + a bit of LECA) for collectors plants like Pink Princess.
Humidity
50–70 % preferred — tolerates 40 % with some tip browning.
Higher humidity gives the largest, most intact leaves and minimises the tip browning that especially affects all-pink leaves. In dry Nordic winter air run a humidifier near the plant. A glass cabinet provides the most stable environment.
Temperature
18–27 °C; damage below 13 °C.
Tropical cultivar; does not tolerate cold draughts or temperatures below 13 °C. Cold exposure causes leaf darkening and drop. Keep clear of unheated entryways and away from cold glass on winter nights.
Fertilizer
Half-strength balanced liquid feed every 4–6 weeks in growing season.
A balanced liquid fertiliser (NPK 10-10-10 or 20-20-20) at half label rate, every 4–6 weeks from April through September. Avoid high-nitrogen formulations — they encourage reversion to plain green. Flush the soil thoroughly every 2–3 months to prevent salt buildup, which especially affects all-pink leaves.
Seasonal: No feeding from October through March.
Pruning
Cut off any fully-reverted (all-green) growth above the last variegated leaf.
If a stem reverts entirely to plain dark green, cut it off at the next node above the last variegated leaf. Reverted growth is faster and more vigorous than variegated growth, so leaving it in place lets the all-green sport take over. Cuttings of reverted stems still produce occasional pink leaves over time but are no longer reliably variegated. Always wear gloves — Philodendron sap contains calcium oxalate raphides. Sterilise scissors between plants.
Repotting
Every 2–3 years in spring; prefers being slightly pot-bound.
Move up by a single pot size when roots fill the pot. Spring is best, before the main growth flush. Pink Princess responds well to a moss pole, totem, or trellis; provide one at potting and train the climbing stem against it.
Stem cuttings — node cuttings
easy~Roots in 4–8 weeksCut the stem at a node, ideally including 1 leaf above the node and an aerial root if present. Always include at least one variegated leaf above the node — the cutting's variegation potential depends on the parent stem's chimeric tissue at that node. Wear gloves. Place in water, sphagnum moss, or aroid mix at 22–25 °C with bright indirect light. Roots emerge in 4–8 weeks. Pink-dominant cuttings are weaker and slower; choose cuttings with a mix of green and pink for the best chance of vigorous variegated regrowth.
Air layering
moderate~Roots in 6–10 weeksFor larger plants. Make a shallow upward cut into the stem just below a node, dust with rooting hormone, wrap with damp sphagnum moss inside a clear plastic sleeve, and seal both ends. Roots become visible through the moss in 6–10 weeks; cut below the new root mass and pot up. The advantage over cuttings is a guaranteed-rooted top.
Common problems
Reversion to plain green leaves
Symptom
New leaves emerge with no pink at all; existing variegated leaves remain unchanged.
Cause
Insufficient light is the most common cause. The variegation is chimeric — a genetic mosaic — and the plant naturally favours the more efficient all-green tissue under low-light stress. Old plants and plants under stress (transplanting, drought, overwatering) also revert.
Fix
Move to brighter indirect light or add a full-spectrum grow light at 12 hours/day. Cut off any fully-reverted stem at the next node above the last variegated leaf — leaving it lets the all-green sport take over. New variegated growth typically resumes within 2–3 months in better light. Cuttings from a stable parent line revert less than cuttings from already-unstable specimens.
Full guide: Why Is My Variegated Plant Losing Its Variegation?All-pink leaves crisping at the edges
Symptom
Fully pink leaves turn brown and crispy at the edges within weeks of unfurling.
Cause
All-pink leaves have no chlorophyll and cannot photosynthesise; they are sustained by the rest of the plant and are weak, with a much higher water and nutrient demand per cm of leaf. They are the first to crisp under stress.
Fix
Maintain consistent humidity (50 %+), use filtered water, and avoid letting the soil fully dry out. Some loss of all-pink leaves is unavoidable — they have a limited lifespan even on a healthy plant. Many collectors deliberately remove brand-new all-pink leaves to redirect energy to the more sustainable half-and-half leaves.
Bright pink turning pale orange in summer
Symptom
Pink variegation fades to pale orange or peach during the summer months.
Cause
Direct sun bleaching, or excessive heat above 30 °C.
Fix
Move further from direct summer sun, increase ventilation, or shade with a sheer curtain during peak afternoon. Pink colour usually recovers in autumn and winter as light intensity drops.
Soft yellow leaves and mushy stem
Symptom
Leaves yellow and droop; stem base goes soft and dark; foul smell.
Cause
Root rot from chronic overwatering.
Fix
Take healthy stem cuttings from above the rotted area immediately as a backup. Wear gloves. Discard the rotted material and contaminated soil. Sterilise the pot before reuse. Switch to a chunkier well-draining mix and reduce watering frequency.

Symptom
Recently purchased 'Pink Princess' (or 'Pink Congo') turns plain green over 3–9 months and never produces pink leaves again.
Cause
The plant was Philodendron 'Pink Congo' — a scam product. Pink Congo is plain Philodendron 'Congo' chemically injected with ethylene to produce temporary pink leaves. The chemical wears off and new growth emerges plain green. There is no real Pink Congo cultivar.
Fix
Nothing will restore the pink — the plant is genuinely a plain green Philodendron 'Congo'. To avoid the scam, look for: (1) chimeric patchy/speckled pink, never solid uniform pink; (2) burgundy-red leaf undersides (Pink Congo has plain green undersides); (3) a verified seller that names the cultivar specifically as 'Pink Princess' with photos of older plants showing stable variegation. If buying online, request photos of multiple leaves on the same plant — chimeric variegation should look different on each leaf. If the variegation looks suspiciously uniform, walk away.

Toxicity & safety
Chewing the plant releases needle-sharp calcium oxalate raphides into the mouth, causing intense burning, swelling of the lips and tongue, drooling, and difficulty speaking. Sap on skin causes contact dermatitis.
Mechanism: Insoluble calcium oxalate raphides physically penetrate mucosa.
Philodendron toxicity — NCBI / PFAFOral irritation, intense burning, drooling, vomiting, difficulty swallowing. Severe airway swelling possible (rare).
Mechanism: Insoluble calcium oxalate raphides physically penetrate oral mucosa.
Philodendron — ASPCA Toxic and Non-Toxic PlantsOral irritation, intense burning, drooling, vomiting, difficulty swallowing.
Mechanism: Insoluble calcium oxalate raphides physically penetrate oral mucosa.
Philodendron — ASPCA Toxic and Non-Toxic PlantsThe 'Pink Congo' scam may be the most successful retail-plant fraud of the 2010s aroid bubble. Plain Philodendron 'Congo' plants were injected with ethylene gas (a plant hormone that triggers chlorophyll breakdown) to force new leaves to emerge bright pink. The treated plants were sold as 'Pink Congo' for €30–80, and the pink reliably faded to plain green within 3–9 months. Wholesale operations in the Netherlands and Germany sold thousands of these before consumer-protection bodies and plant influencers exposed the fraud around 2019. Some major retailers still occasionally stock them — buyer awareness is the only defence.
Frequently asked · 5
Is Philodendron 'Pink Princess' the same as Pink Congo?+
No, and this is the most important question to ask before buying. Pink Princess (Philodendron erubescens 'Pink Princess') is a genuine cultivar with chimeric pink-and-green variegation that varies leaf-to-leaf. Pink Congo is a SCAM — plain Philodendron 'Congo' plants chemically injected with ethylene to force temporary pink leaves that fade to plain green within 3–9 months. To tell them apart: real Pink Princess has irregular patchy/speckled pink (never solid uniform pink), burgundy-red leaf undersides (Pink Congo has plain green undersides), and produces new variegated leaves continuously. Pink Congo has uniform-pink whole leaves and produces all-green new growth after the chemical wears off. If a 'Pink Congo' is offered for sale, walk away.
Is Philodendron 'Pink Princess' safe for cats and dogs?+
No — ASPCA lists Philodendron as toxic to cats, dogs, and horses. All parts contain calcium oxalate raphides — needle-sharp crystals that physically penetrate the oral mucosa when chewed, causing intense burning, drooling, vomiting, and swelling of the lips and tongue. If your pet chews the plant, rinse their mouth with cold water and contact a vet. Keep well out of reach.
Why is my Pink Princess losing its pink?+
Almost always insufficient light. Pink variegation is highly light-dependent — below 10,000 lux the plant produces fewer pink sections per leaf and is more prone to reversion. Move to brighter indirect light or add a full-spectrum grow light at 12 hours/day. Cut off any fully-reverted (all-green) stems at the next node above the last variegated leaf — reverted growth is faster and will crowd out variegated growth. New variegated growth typically resumes within 2–3 months in better light. Some specimens are unstable and will keep reverting; the only fix is replacing them with a fresh cutting from a stable line.
How do I get more pink on my Pink Princess?+
Three factors increase pink expression. (1) Light — at least 12,000 lux; brighter indirect light produces more pink sections per leaf. (2) Cutting selection — when propagating, choose a node with a mix of green and pink in the leaves above; pure-green nodes produce green plants, pure-pink nodes produce weak unsustainable plants. (3) Patience — pink content stabilises over 6–18 months as the chimeric tissue settles. Do NOT use ethylene treatments or 'pink boosters' marketed online; these are the same scam as Pink Congo and produce only temporary pink that fades to green.
How do I propagate Philodendron 'Pink Princess'?+
Stem node cuttings. Cut the stem at a node with at least one leaf above the node and an aerial root if present. Always choose a node where the leaves above show a mix of green and pink — pure-green nodes produce green plants, pure-pink nodes produce weak unsustainable plants. Wear gloves — the sap is irritating. Place in water, sphagnum moss, or aroid mix at 22–25 °C with bright indirect light. Roots emerge in 4–8 weeks. Air layering also works well for larger plants and produces a guaranteed-rooted cutting before separation.
