What is Philodendron White Knight?

The Philodendron White Knight is a relatively rare and unique cultivar in the Philodendron genus. Originally hailing from the tropical regions of Central and South America, this particular plant is loved for its striking variegated leaves. The foliage is characterized by a creamy white to pink coloration juxtaposed against dark green. The leaves are usually elongated, arrow-shaped, and have a glossy surface.

The plant displays a climbing or trailing growth pattern and uses aerial roots to attach itself to surfaces, making it an excellent choice for hanging baskets or for training up a trellis. The variegation in the leaves occurs due to a lack of chlorophyll in some of the plant's cells, creating a striking contrast. It's worth noting that the pattern of variegation can differ from leaf to leaf, making each plant truly unique.

Soil Requirements

Philodendron White Knight prefers well-draining soil that retains some moisture. A mixture of potting soil, perlite, and orchid bark tends to work well for this plant. This provides both the aeration and moisture retention needed for optimal growth. A pH level ranging from 6.0 to 7.0 is generally best for this particular philodendron.


The Philodendron White Knight does not require excessive watering. It's best to let the top inch of soil dry out before watering again. Use your finger to check the soil's moisture level; if it feels dry to the touch, it's time to water. Signs of over-watering include yellow leaves and root rot, while under-watering will cause the leaves to droop and eventually turn brown.

Light Requirements

This plant prefers bright, indirect light but can tolerate lower light conditions. Direct sunlight should be avoided, as it can scorch the leaves, leading to discoloration and damage. If you're growing the plant indoors, placing it near an east or north-facing window is usually a good choice. For those using artificial light, ensure that the plant receives at least 8 hours of light per day.

Temperature and Humidity

The Philodendron White Knight thrives in a temperature range of 65-80°F (18-27°C). It also appreciates higher humidity but can tolerate a bit less. To increase humidity, consider placing the pot on a tray filled with water and pebbles, but make sure the pot is not sitting in the water. Alternatively, you can use a humidifier to maintain an optimal environment.


Fertilize your Philodendron White Knight every 4-6 weeks during the growing season (spring and summer) using a balanced liquid fertilizer. Make sure to follow the directions on the fertilizer package for dilution rates. During fall and winter, reduce fertilization to once every two months or stop altogether.

Propagation Techniques

Propagating the Philodendron White Knight is relatively straightforward. One of the most common methods is stem cutting. Here's a step-by-step guide:

  1. Identify a healthy stem that has at least two leaves and an aerial root.
  2. Using a clean, sharp pair of scissors, cut the stem just below the aerial root.
  3. Place the cutting in a glass of water or directly into soil.
  4. If using water, wait until roots develop to about 2 inches before transplanting into soil.
  5. Keep the cutting in bright, indirect light and maintain high humidity for best results.
  6. Once the cutting is well-rooted in soil, resume normal care routines.

Pruning is essential for maintaining the shape and health of your Philodendron White Knight. Remove any yellow or brown leaves and prune back any overly long stems to encourage bushier growth. The best time to prune is in the spring or early summer. Always use clean, sharp scissors to make your cuts, and consider applying a rooting hormone to the cut areas to prevent disease.

Growing Philodendron White Knight From Seed

Growing this plant from seed is a less common approach but can be done. Seeds should be sown in a well-draining soil mix and kept in a warm, humid environment. Cover the seed tray with plastic wrap to maintain humidity. Once the seeds germinate, usually within 2-3 weeks, remove the plastic wrap. When the seedlings have at least two leaves, they can be transplanted into individual pots. Be patient, as growing from seed is a long process and can take several months to a year to achieve a sizeable plant.

How to Pot or Repot Philodendron White Knight

Potting or repotting is best done during the spring or early summer. Choose a pot that is 1-2 inches larger in diameter than the current one and has good drainage. Fill the bottom of the new pot with a layer of soil, then carefully remove the plant from its current pot. Place it in the new pot and fill with soil, pressing down lightly to remove air pockets. Water the plant thoroughly after repotting.

Benefits of Having Philodendron White Knight at Home

This plant not only adds a touch of beauty to your home but also has air-purifying qualities. It is known to remove pollutants like formaldehyde from the air. However, it's important to note that the plant is toxic if ingested, so keep it away from pets and small children. The variegated leaves add an element of sophistication and uniqueness that few other houseplants can match.

How to Get Flowers Bloom in Philodendron White Knight

Though flowering is rare in indoor conditions, you can encourage your Philodendron White Knight to bloom by providing optimal care. This includes regular fertilization with a high-phosphorus formula and maintaining a consistent watering schedule. If you're lucky, you may see a bloom, which is usually a small, non-showy inflorescence typical of philodendrons.

Common Pests & Plant Diseases

Common pests include aphids, mealybugs, and spider mites. Wiping down leaves with a mixture of water and mild dish soap can help combat these pests. Over-watering can lead to root rot, a common disease. Ensuring your plant has well-draining soil and a proper watering schedule will mitigate most risks.

Common Problems and Solutions

If your Philodendron White Knight is losing its variegation, it may be due to insufficient light. Move the plant to a brighter location but avoid direct sunlight. If leaves are yellowing, it could be a sign of over-watering. Let the soil dry out a bit before the next watering. Brown leaf tips are often a sign of low humidity; consider using a humidifier.
