1. Introduction to Philodendron Burle Marx: The Zigzag Wonder
1.1. What is Philodendron ‘Burle Marx’?
The Philodendron ‘Burle Marx’ is a stunning and widely popular hybrid cultivar within the Philodendron genus. It is particularly distinguished by its unique leaf morphology: its glossy, medium to dark green leaves are deeply lobed or dissected, but often in an irregular, wavy, or “zigzag” pattern along the margins. This gives each leaf a characteristic, somewhat abstract shape that sets it apart from more uniformly lobed Philodendrons. Named after the famous Brazilian landscape architect Roberto Burle Marx, who was known for his use of bold, organic shapes in his designs, this plant embodies an artistic flair. It typically grows in a bushy, somewhat sprawling habit, making it an excellent choice for tabletops, shelves, or as a dense floor plant.
1.2. Reasons for its Appeal
Philodendron ‘Burle Marx’ captivates plant enthusiasts for several compelling reasons:
- Unique Leaf Shape: Its irregularly lobed, wavy, or zigzag leaves provide an artistic and highly distinctive visual appeal.
- Compact & Bushy Growth: It typically forms a dense, bushy clump, making it ideal for various indoor settings without requiring extensive climbing support.
- Lush Green Foliage: Its vibrant green leaves bring a classic tropical feel to any space.
- Relatively Easy Care: It is considered a relatively forgiving and low-maintenance Philodendron, suitable for both beginners and experienced growers.
2. Origins and Distinguishing Characteristics
2.1. Origins
The Philodendron ‘Burle Marx’ is a cultivated hybrid, named in honor of Roberto Burle Marx, a pioneering landscape architect who often incorporated Philodendrons into his work. As a hybrid, it does not have a specific wild origin like a species. Its genetic lineage traces back to various Philodendron species native to the tropical rainforests of Central and South America. Its development is a testament to horticultural efforts to create visually unique and robust cultivars for indoor cultivation.
2.2. Leaf Morphology and Shape
The leaves of Philodendron ‘Burle Marx’ are its most defining characteristic. They are typically medium-sized, somewhat elongated, and a glossy medium to dark green. The distinguishing feature is their deeply lobed or dissected margins, which often have an irregular, wavy, or zigzag pattern. This gives the leaf a unique, almost serrated or asymmetrical appearance, evolving as the leaf matures. The leaves are generally entire (not fenestrated with internal holes) but their deep, irregular lobing is their primary ornamental feature.
2.3. Growth Habit and Rate
Philodendron ‘Burle Marx’ typically exhibits a compact, bushy, and somewhat sprawling or self-heading growth habit. While it can trail from hanging baskets or shelves, it tends to grow outwards and upwards in a dense clump rather than actively climbing with aerial roots like many other vining Philodendrons. Its growth rate is generally moderate under optimal conditions, gradually filling out its space to become a substantial plant without needing a moss pole for support. Regular pruning can help control its size and shape while promoting bushier growth.
2.4. Toxicity
Like most other Philodendron species, Philodendron ‘Burle Marx’ is considered toxic to pets (cats, dogs) and humans if ingested. It contains calcium oxalate crystals, which can cause irritation and swelling of the mouth, throat, and digestive tract, leading to discomfort, vomiting, and difficulty swallowing. It is advisable to keep this plant out of reach of pets and small children.
2.5. Comparison to Similar Philodendrons (Imperial Green, Xanadu, Tortum)
Philodendron ‘Burle Marx’ is quite distinct due to its irregular, zigzag lobing, but it can be compared to other Philodendrons with complex or deeply cut leaves.
- Philodendron ‘Burle Marx’: Characterized by deeply lobed leaves with irregular, wavy, or zigzag margins on glossy green foliage. It typically has a bushy, compact, sprawling, or semi-self-heading growth habit.
- Philodendron ‘Imperial Green’: A self-heading Philodendron with very large, glossy, deep green leaves. However, its leaves are entire (smooth-edged), not lobed or zigzagged like ‘Burle Marx’.
- Philodendron xanadu: Also a self-heading Philodendron with deeply lobed leaves. However, P. xanadu leaves are typically more symmetrically and regularly lobed into “fingers,” lacking the distinctive irregular, zigzag pattern of ‘Burle Marx’.
- Philodendron tortum: Features leaves that are deeply dissected into very slender, finger-like, often twisted segments, giving a fern-like or skeletal appearance. While also intricate, its leaf form is distinctly different from the broader, zigzag lobes of ‘Burle Marx’.
- Philodendron ‘Jungle Boogie’ (or ‘Tiger Tooth’): Has elongated leaves with serrated or ‘saw-toothed’ edges, typically with more uniform cuts compared to the irregular zigzag of ‘Burle Marx’. It is also a self-heading to semi-climbing plant.
The unique combination of its irregular, wavy, or zigzag lobed leaves and its compact, bushy growth habit clearly distinguishes Philodendron ‘Burle Marx’.

3.1. Light Requirements
Philodendron ‘Burle Marx’ thrives in bright, indirect light. Place your plant near a window that gets plenty of ambient light but is shielded from harsh direct sunbeams, especially during the midday and afternoon hours. East-facing windows are often ideal, providing gentle morning sun. For south or west-facing windows, use a sheer curtain to diffuse intense light or place the plant a few feet away from the window. Direct sunlight can easily scorch its leaves, leading to unsightly brown spots and potentially dulling its vibrant green color. Conversely, insufficient light can lead to slower growth, smaller leaves, and a less pronounced lobing pattern. Regularly rotating the plant ensures even light exposure and balanced growth.
3.2. Temperature and Humidity
As a plant from warm, humid climates, Philodendron ‘Burle Marx’ prefers consistently warm temperatures, ideally ranging from 18-27°C (65-80°F). It’s crucial to protect it from cold drafts and sudden temperature fluctuations, as temperatures below 15°C (59°F) can stress the plant, slow growth, and cause leaf damage. Avoid placing the plant near open doors, air conditioning vents, or heating units.
Philodendron ‘Burle Marx’ prefers moderate to high humidity (50-70% or higher). While it can tolerate average household humidity, optimal growth and pristine leaf appearance (including the development of its unique lobing) are achieved with higher moisture levels. Signs of insufficient humidity might include crispy brown leaf edges or tips. You can increase humidity by misting the leaves regularly, using a room humidifier, placing the pot on a pebble tray filled with water (ensuring the pot itself doesn’t sit in the water), or grouping the plant with other humidity-loving plants to create a humid microclimate.
3.3. Watering Practices
Proper watering is critical for Philodendron ‘Burle Marx’. It prefers its soil to dry out partially between waterings to prevent root rot. Water deeply when the top 1 inch (2.5 cm) of soil feels dry to the touch. Ensure that the pot has excellent drainage holes and that any excess water drains out completely from the bottom. Never allow the plant to sit in standing water, as this is the primary cause of root rot. Overwatering is a common mistake, so it’s generally safer to err on the side of underwatering.
The frequency of watering will depend on environmental factors like light, temperature, and humidity, as well as the pot size and soil mix. Expect to water more often during the warmer, active growing months (spring and summer), typically about once a week. During the cooler, dormant months of fall and winter, reduce watering frequency significantly, allowing the soil to dry out more thoroughly between waterings. Drooping leaves can indicate both underwatering and overwatering (due to root damage).
3.4. Optimal Soil Mix and Repotting
A well-draining, airy, and nutrient-rich potting mix is essential for Philodendron ‘Burle Marx’. This mimics the loose, organic matter it would find in its native environment. An ideal mix should promote good aeration while retaining sufficient moisture. A suitable blend, often referred to as an “aroid mix,” can include:
- High-quality indoor potting mix (approximately 50%)
- Perlite or pumice (approximately 20-30%) for excellent drainage and aeration
- Orchid bark (approximately 20-30%) for chunkiness and improved air circulation
Repotting: Repot your Philodendron ‘Burle Marx’ typically every 1-2 years, or when you notice it has become root-bound (roots growing out of drainage holes, water running straight through the pot too quickly, stunted growth). Spring is the best time to repot, as the plant is entering its active growth phase. Choose a new pot that is only 1-2 inches larger in diameter than the previous one, ensuring it has ample drainage.
3.5. Fertilization Strategies
During the growing season (spring and summer), fertilize your Philodendron ‘Burle Marx’ monthly with a balanced liquid fertilizer, diluted to half the recommended strength. This provides the necessary nutrients to support vigorous growth and maintain its lush foliage and unique lobing. Reduce or completely stop fertilizing during the fall and winter months when the plant’s growth naturally slows. Over-fertilization can lead to salt buildup in the soil, which can burn the roots and cause leaf damage (e.g., crispy brown tips). Always water the plant thoroughly before applying fertilizer to protect the roots.
3.6. Pruning and Maintenance
Regular pruning is beneficial for Philodendron ‘Burle Marx’ to maintain its desired bushy shape and remove any unhealthy foliage. Remove any yellowing, brown, or damaged leaves using clean, sharp scissors or pruning shears. Pruning can be done during the active growing season. Regularly wipe the leaves with a damp cloth to remove dust, which improves the plant’s ability to photosynthesize and keeps the foliage vibrant. While it primarily grows as a bushy plant, it can also trail, making it suitable for hanging baskets or shelves where its unique leaves can cascade gracefully.
4. Propagation Techniques: Expanding Your Collection
Propagating Philodendron ‘Burle Marx’ is a straightforward and rewarding way to create new plants. The most common and effective method is using stem cuttings. The best time for propagation is during the spring or early summer when the plant is actively growing.
4.1. Stem Cuttings
- Select a Healthy Stem: Choose a healthy, mature stem section that has at least one node (the bump on the stem where a leaf emerges from the stem) and preferably one or two healthy leaves.
- Sterilize Tools: Always use clean, sharp, and sterilized pruning shears or a knife to make your cuts. This prevents the spread of diseases.
- Make the Cut: Cut the stem just below a node. Remove any lower leaves that would be submerged in your chosen rooting medium to prevent rot.
- Rooting Hormone (Optional): Applying a rooting hormone (powder or gel) to the cut end can stimulate faster and more robust root development.
- Rooting Medium Options:
- Water Propagation: Place the cutting in a clear jar with fresh water, ensuring the node is fully submerged. Change the water every few days to keep it clean and prevent bacterial growth. Roots typically begin to form within a few weeks.
- Sphagnum Moss: Plant the cutting in moist, but not soggy, sphagnum moss. This medium provides excellent aeration and moisture retention, often leading to robust root development.
- Soil: You can also plant the cutting directly into a small pot filled with a well-draining, airy potting mix suitable for aroids. Keep the soil consistently moist but not soggy.
- Provide Optimal Environment: Place your cuttings in a warm location that receives bright, indirect light. High humidity (e.g., within a propagation box or covered with a clear plastic bag to create a mini-greenhouse effect) will significantly accelerate the rooting process.
- Potting Up: Once the roots are a few inches long (for water or moss propagation), or significant new leaf growth is visible (for soil propagation), your new plant is ready to be transitioned to a larger pot with its permanent potting mix.
5. Troubleshooting Common Issues: Pests, Diseases, and Environmental Stress
While generally robust, Philodendron ‘Burle Marx’ can encounter a few common problems if its specific care requirements are not met. Prompt identification and action are crucial for maintaining its health.

5.1. Watering Issues
- Overwatering: This is the most common cause of problems. Symptoms include yellowing leaves (particularly older, lower ones), black/brown spots on leaves, a mushy stem near the soil line, and a foul, moldy smell from the soil. This eventually leads to root rot.
- Solution: Allow the top 1 inch (2.5 cm) of soil to dry out completely between waterings. Ensure the pot has excellent drainage. If root rot is suspected, unpot the plant, trim any rotted, mushy roots, and repot in fresh, well-draining soil. Reduce watering frequency, as it’s generally safer to err on the side of underwatering.
- Underwatering: Symptoms include drooping or curled leaves, crispy brown edges or tips, and overall dull foliage. The plant may visibly droop when thirsty.
- Solution: Increase watering frequency. Ensure you are watering thoroughly so that water drains from the bottom of the pot, indicating the entire root ball has been moistened.
5.2. Light Issues
- Insufficient Light: Can lead to slower growth, smaller leaves, leggy stems (long gaps between leaves on the stem as it stretches for light), and less pronounced lobing.
- Solution: Move the plant to a location that receives bright, indirect light. Consider supplementing with a grow light if natural light levels are consistently low.
- Too Much Direct Light: Harsh direct sun, especially during midday, can cause leaf scorch. Symptoms include brown, crispy patches or a faded appearance on the leaves.
- Solution: Relocate the plant to a spot with filtered light, or use sheer curtains to diffuse intense sunlight.
5.3. Humidity and Temperature Stress
- Low Humidity: Often causes the leaf edges or tips to turn brown and crispy. New leaves might struggle to unfurl properly and could become distorted.
- Solution: Increase ambient humidity using a humidifier, pebble tray, or by grouping plants together. Regular misting can provide some benefit.
- Cold Stress: Exposure to temperatures below 15°C (59°F) can severely stress the plant, leading to leaf damage, wilting, and overall decline.
- Solution: Ensure the plant is in a consistently warm environment (18-27°C is ideal) and protected from cold drafts from windows or air vents.
5.4. Pests
Common houseplant pests like mealybugs, spider mites, thrips, and scale can occasionally infest Philodendron ‘Burle Marx’.
- Symptoms: Visible insects (mealybugs with white, cottony masses; spider mites with fine webbing; thrips with silver streaks and black frass; scale with hard, immobile bumps), sticky residue (honeydew), or speckled, distorted leaves.
- Solution: Regularly inspect your plant, especially the undersides of leaves and stem crevices. Isolate infested plants immediately. Treat with appropriate organic pest control methods such as insecticidal soap, neem oil, or by wiping pests off with an alcohol-dipped cotton swab. Increasing humidity can help deter spider mites.
5.5. Diseases
- Root Rot: This is a serious fungal disease, almost always a result of overwatering and poorly draining soil.
- Symptoms: Yellowing, wilting leaves (even when the soil is wet), a mushy stem near the soil line, and black/brown, foul-smelling roots.
- Solution: Immediately remove the plant from its pot. Carefully inspect the roots and prune away all affected (mushy, black) sections with sterilized shears. Repot the plant in fresh, well-draining aroid mix, and adjust your watering schedule to allow the soil to dry adequately between waterings.
- Fungal Leaf Spot: Can appear as various spots on the leaves.
- Solution: Improve air circulation around the plant, reduce overly high humidity, and remove affected leaves. Fungicides may be used in severe cases.
