What Is a Philodendron Prince of Orange?

Philodendron Prince of Orange is a patented hybrid cultivar of Philodendron erubescens. It produces self-heading, non-clumping rosettes of large leaves that emerge bright copper-orange and mature to deep green. It reaches 24 to 35 inches tall indoors. U.S. Plant Patent PP6,797 was granted to Howard N. Miller in 1989 and expired in 2008.

The species belongs to the Araceae family. It was bred for its striking ontogenic color change, in which each new leaf unfurls in a vivid orange-salmon hue before transitioning through bronze and yellow tones and finally settling into a glossy deep green. According to the UF/IFAS Gardening Solutions program, this hybrid does well in low light and maintains its orange color in all levels of light, though optimal conditions produce the most intense coloration. It is not a trailing vine. It is a self-heading hybrid that grows from a central base. Many buyers mistakenly expect it to climb like a heartleaf philodendron. You can read about the differences in our guide to heartleaf philodendron care indoors.

How Much Light Does a Philodendron Prince of Orange Need Indoors?

It needs 150 to 800 foot-candles of bright, indirect light to maintain optimal leaf size and color intensity. It tolerates as low as 75 foot-candles, but growth slows and orange coloration fades. Direct afternoon sun scorches foliage. An east-facing window or 3 to 5 feet from a south window provides ideal indoor light.

According to UF/IFAS Ask IFAS, commercial philodendron production requires 150 or more foot-candles to maintain color and leaf size. The UF/IFAS Gardening Solutions program notes that Prince of Orange maintains its orange color in all light levels, but low light produces smaller leaves and less vivid new growth. Direct south-facing sun causes bleached patches and brown scorch marks. If you only have a south-facing window, place the plant 3 to 5 feet back or filter the light with a sheer curtain. North-facing windows provide gentle light that works in summer but may be too dim in winter. If your space lacks natural light, LED grow lights set 12 to 18 inches above the canopy can sustain the plant. Leaves that turn uniformly pale green often signal light levels have dropped below the 75 foot-candle minimum.

What Is the Best Soil Mix for a Philodendron Prince of Orange?

Use a well-draining peat-based potting mix with a pH between 6.0 and 7.0. A standard indoor mix amended with 20 to 30 percent perlite or orchid bark improves drainage. Heavy, water-retentive soils cause root rot. The self-heading root system needs oxygen, so avoid pure garden soil or mixes without aeration amendments.

According to UF/IFAS Ask IFAS, commercial production uses a pH between 6.0 and 6.5. The K-State Extension program recommends a well-draining potting mix for home growers. In the wild, philodendron roots cling to bark and decaying leaf litter. They are not buried in dense clay. Your indoor mix should mimic this loose, airy structure. Combine two parts peat-based potting soil with one part perlite and one part orchid bark. This blend holds enough moisture for root uptake while allowing excess water to drain freely. Never use unamended garden soil. It compacts indoors and suffocates the fine roots. If the mix is too alkaline, micronutrients like iron become locked out and leaves yellow between the veins. Refresh the soil completely every two to three years when you repot. Old soil breaks down and loses its structure.

How Often Should You Water a Philodendron Prince of Orange?

Water when the top 1 to 2 inches of soil feel dry to the touch. In most indoor conditions this means once every 7 to 10 days in spring and summer, and every 10 to 14 days in fall and winter. Always use room-temperature water. Cold water below 60 degrees Fahrenheit can shock tropical roots.

The finger test is the most reliable method. Stick your index finger into the soil up to the second knuckle. If it feels dry, water thoroughly until liquid drains from the bottom holes. If it feels damp, wait two to three days and test again. According to the K-State Extension program, you should water when the top inch of soil is dry. Overwatering is the leading cause of death for this plant. Soggy soil deprives roots of oxygen and invites fungal pathogens. Empty the saucer after 30 minutes. Never let the pot sit in standing water. In winter, when evaporation slows, extend the interval between waterings. The plant enters a semi-dormant state and uses less moisture. If your tap water is heavily chlorinated, consider using filtered water or leaving tap water out overnight. You can read more about water quality in our guide to best water for calathea.

Warning: Cold Water Shock

Always use room-temperature water between 65 and 75 degrees Fahrenheit. Cold tap water below 60 degrees Fahrenheit can damage the tender tropical root system and cause leaf drop.

What Temperature and Humidity Does a Philodendron Prince of Orange Need?

The ideal temperature range is 65 to 85 degrees Fahrenheit. Temperatures below 50 degrees Fahrenheit cause permanent tissue damage. Average household humidity between 40 and 60 percent is sufficient, though the plant prefers 50 to 70 percent. Keep it away from cold drafts, air conditioning vents, and heating registers.

According to UF/IFAS Ask IFAS, the optimal indoor temperature for philodendron production is 70 to 80 degrees Fahrenheit. The K-State Extension program advises keeping the plant above 50 degrees. This makes it unsuitable for unheated porches or drafty windowsills in winter. Humidity below 30 percent can cause brown, crispy leaf tips. If your home is dry, group plants together, place a pebble tray beneath the pot, or run a small humidifier nearby. Misting provides only temporary relief and is not a substitute for ambient humidity. Avoid placing the plant directly above radiators or next to forced-air vents. The hot, dry air will desiccate the foliage faster than the roots can replace the moisture.

How Do You Fertilize a Philodendron Prince of Orange for Best Growth?

Feed with a 3:1:2 or 3:1:3 NPK liquid fertilizer at half strength every two weeks during spring and summer. Stop feeding in fall and winter when growth slows. Over-fertilizing causes salt buildup, leaf tip burn, and root damage. Always apply to damp soil, never to dry roots.

According to UF/IFAS Ask IFAS, commercial philodendron production uses a 3:1:2 or 3:1:3 NPK ratio for optimal growth. Home growers can replicate this with a standard liquid houseplant fertilizer diluted to half the label rate. The K-State Extension program recommends a balanced liquid fertilizer every 4 to 6 weeks during the growing season. A 20-20-20 formula at half strength works in a pinch, but a 3:1:2 ratio such as 24-8-16 more closely matches the plant’s actual nutrient demand. High nitrogen supports the lush foliage; lower phosphorus prevents unnecessary salt accumulation. Flush the soil every two to three months by watering deeply and allowing excess to drain. This leaches accumulated fertilizer salts that would otherwise burn the root tips. If you see white crust on the soil surface, it is a sign of salt buildup. Flush immediately and reduce your feeding concentration.

Why Are My Prince of Orange Leaves Turning Green Instead of Orange?

New leaves naturally emerge bright orange, transition through bronze and salmon, and mature to deep green. This is normal ontogenic color change, not a health problem. The orange color is temporary and lasts only on the newest one to three leaves at any time. Older leaves turning green is expected biology.

This is the single most common worry among new owners. When a new leaf unfurls, it displays a vivid copper-orange or salmon-pink hue. Over the next two to four weeks, that same leaf will shift through yellow-bronze tones and finally settle into a glossy deep green. The plant always has a crown of colorful new foliage above a base of green mature leaves. If the newest leaves emerge already green or pale, the plant likely needs more light or fertilizer. Move it to a brighter location and feed with a half-strength 3:1:2 NPK formula. If only the oldest bottom leaves are yellowing, that is natural senescence. Remove them to keep the plant tidy.

Is Philodendron Prince of Orange a Climbing or Self-Heading Plant?

It is a self-heading, non-climbing, non-vining plant. It grows as a compact upright rosette from a central stem base. It does not produce long trailing vines and does not need a moss pole. This distinguishes it sharply from vining philodendrons like heartleaf philodendron.

According to Iowa State University Extension, Prince of Orange is classified as a compact, non-climbing variety of P. erubescens. The self-heading habit means all leaves emerge from a central base rather than along an elongating vine. It will never climb your bookshelf or drape from a hanging basket. It stays bushy and upright, making it ideal for tabletops, desks, and floor stands in small apartments.

How Do You Propagate a Philodendron Prince of Orange at Home?

Propagate from stem cuttings with at least one node and one leaf, placed in room-temperature water or moist potting mix. Root initials appear in 7 to 14 days. Transplant when roots reach 2 to 3 inches. Home propagation for personal use is legal; the U.S. Plant Patent PP6,797 expired in 2008.

According to Iowa State University Extension, philodendrons propagate readily from stem cuttings. The node is the critical structure. It is the small bump on the stem where leaves and roots emerge. A cutting without a node will not root. Use clean, sharp scissors. Cut just below a node at a 45-degree angle. Remove the lowest leaf so the node sits in water without submerged foliage rotting. Place the cutting in a clear glass or jar filled with room-temperature water. Change the water every 3 to 5 days to prevent bacterial growth. Keep the jar in bright, indirect light. Once roots are 2 to 3 inches long, transplant into a small pot with moist potting mix. You can also propagate in sphagnum moss. Our guide on how to propagate in sphagnum moss explains that method in detail.

StageWhat to Look ForTypical Timeline
Root initialsSmall white bumps at the nodeDay 7-10
Side rootsOne-quarter inch white root hairsDay 10-14
Primary rootsTwo to three inches long, branchingDay 14-21
Soil transitionRoots anchored, new leaf unfurlingDay 21-28
  1. Identify a healthy stem with at least one mature leaf and one visible node.
  2. Cut just below the node at a 45-degree angle using clean, sharp scissors.
  3. Remove the lowest leaf so only the stem and node sit in water.
  4. Place the cutting in a clear container with room-temperature water covering the node.
  5. Set the container in bright, indirect light away from direct sun.
  6. Change the water every 3 to 5 days to prevent algae and bacteria.
  7. Wait until roots reach 2 to 3 inches, then transplant into moist potting mix.

How Do You Prune a Philodendron Prince of Orange?

Prune to remove dead or yellowing leaves and to control height. Use clean, sharp scissors. Cut spent leaves at the base where they meet the stem. Remove lower leaves as they naturally age. Pruning is minimal because the self-heading habit keeps a naturally compact shape.

The plant does not require aggressive shaping. Its self-heading rosette form stays naturally bushy. The main pruning task is removing old leaves that have turned completely yellow or brown. Snip them at the petiole base where they attach to the main stem. Do not tear them by hand; this can damage the stem tissue and invite infection. If the plant becomes too tall for your space, you can remove the tallest leaf stalks at the base. This encourages the plant to push new growth from the center. Always sterilize your blades with rubbing alcohol or a 10 percent bleach solution between cuts. This prevents spreading bacterial or fungal pathogens from one plant to another.

Pro Tip: Rotate for Even Color

Rotate the pot one-quarter turn every time you water. This ensures all sides receive equal light and prevents lopsided orange coloration on one side of the rosette.

Is Philodendron Prince of Orange Toxic to Cats and Dogs?

Yes. Philodendron Prince of Orange is toxic to cats, dogs, and horses. It contains insoluble calcium oxalate crystals. Chewing the leaves releases needle-like crystals that penetrate mouth and throat tissues, causing immediate pain, swelling, drooling, vomiting, and difficulty swallowing. Keep the plant out of reach of pets and small children.

The ASPCA lists all philodendrons as toxic to both cats and dogs. Prince of Orange shares the identical toxin profile of insoluble calcium oxalates found throughout the genus. Symptoms typically appear within minutes of ingestion. The pet may paw at its mouth, drool excessively, or refuse food. In severe cases, swelling can obstruct the airway. If you suspect your pet has chewed the plant, rinse its mouth with water and contact your veterinarian or the ASPCA Animal Poison Control Center immediately. Do not induce vomiting unless instructed by a professional. If you need pet-safe alternatives, browse our guide to cat-safe plants.

How Do You Repot a Philodendron Prince of Orange?

Repot every two to three years in spring, or when roots grow through drainage holes. Choose a pot only one size larger, 1 to 2 inches wider in diameter. Use fresh peat-based potting mix. The self-heading root system tolerates being slightly pot-bound and may bloom more readily when roots are snug, though blooming is rare indoors.

According to Iowa State University Extension, philodendrons prefer to be slightly root-bound and need repotting only when roots fill the container. To repot, water the plant the day before. This helps the root ball hold together. Gently tip the pot and slide the plant out. Tease apart any circling roots at the bottom. Place a layer of fresh mix in the new pot, set the root ball at the same depth as before, and fill around it with more mix. Press lightly to remove large air pockets. Water thoroughly and place the plant back in its usual light. Avoid fertilizing for four to six weeks after repotting. Fresh mix contains enough nutrients, and the disturbed roots need time to heal before taking up salts.

Frequently Asked Questions

How fast does a Philodendron Prince of Orange grow indoors?

In optimal conditions, it produces one to two new leaves per month during spring and summer. Growth slows in fall and winter when light and temperature drop. It is slower than vining philodendrons because it invests energy in large individual leaves rather than stem elongation.

Can Philodendron Prince of Orange grow in low light?

Yes, it tolerates low light down to approximately 75 foot-candles, but new leaves will be smaller and less vividly orange. For best color intensity and leaf size, provide 150 foot-candles or more.

Why are the leaves on my Prince of Orange turning yellow?

Yellow leaves usually indicate overwatering, but can also signal underwatering, nutrient deficiency, or natural old-age senescence. Check soil moisture first. If the soil is wet and roots smell sour, reduce watering. If dry, water thoroughly. If only the oldest bottom leaves are yellowing, remove them.

Do I need a moss pole for Philodendron Prince of Orange?

No. It is a self-heading plant that grows as an upright rosette. It does not climb and does not need a moss pole, trellis, or basket. It is ideal for tabletops and floor stands without any support structure.

Can I propagate Philodendron Prince of Orange legally?

Yes. Home propagation for personal use is legal. U.S. Plant Patent PP6,797 expired in 2008 after its 20-year term. You may take stem cuttings for your own collection. Commercial propagation and sale may still involve trademark considerations for the cultivar name.

How long do Prince of Orange cuttings take to root in water?

Root initials appear in 7 to 10 days. Roots reach transplantable length of 2 to 3 inches in 14 to 21 days. Change the water every 3 to 5 days for fastest results.
