1. Introduction to Philodendron 69686: The Botanical Enigma
1.1. What is Philodendron 69686?
The Philodendron 69686 is a fascinating and highly prized plant within the Philodendron genus, known by its accession number as its formal scientific name remains undescribed. This numerical designation refers to its catalog entry at the Missouri Botanical Garden, reflecting its mysterious origins. It is a unique hybrid, possibly natural, believed to originate from the rainforests of Brazil. It has recently been unofficially named Philodendron ‘Bette Waterbury’. This Philodendron is instantly recognizable by its bold, deeply lobed leaves that undergo a dramatic transformation as they mature, often becoming hourglass-shaped, tri-lobed, or displaying highly variable, sculptural forms. These rich green, leathery leaves make it a captivating and artistic addition to any indoor plant collection.
1.2. Reasons for its Appeal
Philodendron 69686 captivates plant enthusiasts for several compelling reasons:
- Extraordinary Leaf Morphology: Its deeply lobed leaves, which change shape dramatically with maturity, offer a highly sculptural and artistic aesthetic.
- Botanical Mystery: Its undescribed species status and unknown parentage add an intriguing element of mystery and allure for collectors.
- Robust & Vigorous Growth: Despite its unique appearance, it is considered a relatively easy and vigorous grower, making it a satisfying plant to cultivate.
- Collector’s Item: Its unique features and ongoing botanical study contribute to its high desirability among Aroid collectors.
2. Origins and Distinguishing Characteristics
2.1. Origins and Status
Philodendron 69686 is considered a natural hybrid, believed to originate from the Brazilian rainforests. It was cataloged under accession number 69686 at the Missouri Botanical Garden, hence its informal name. While still awaiting a formal botanical description, it has recently been given the unofficial cultivar name Philodendron ‘Bette Waterbury’. Its exact parentage remains unknown, contributing to its enigmatic status. It is a hemicryptophyte, meaning its perennial buds are at or just below the soil surface.
2.2. Leaf Morphology and Progression
The most defining characteristic of Philodendron 69686 is its highly variable and evolving leaf morphology. The leaves are typically:
- Shape: Young leaves may be more oval, but as the plant matures, they develop into deeply lobed, sculptural forms. They can become distinctly tri-lobed, hourglass-shaped, or even more elongated with narrow central sections and wider lobes at the top and bottom. This variability is a hallmark of the plant.
- Color & Texture: Rich, deep green, with a somewhat leathery or thick texture. The prominent veins can add to its sculptural look. Leaves can grow up to 2 feet (60 cm) long.
2.3. Growth Habit and Rate
Philodendron 69686 is an upright to semi-climbing Aroid. It has a climbing growth pattern and benefits greatly from vertical support. It produces aerial roots, which it uses to attach to structures. Indoors, it can reach heights of 80-120 cm (2.5-4 feet) and spread 60-90 cm (2-3 feet) wide, growing taller with a moss pole or other support. It can also be allowed to cascade from a hanging basket. Its growth rate is generally moderate to fast under optimal conditions, producing new leaves fairly quickly, and it is known to make “pups” (new baby plants).
2.4. Toxicity
Like most other Philodendron species, Philodendron 69686 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 (Joepii, Mexicanum, Pedatum)
Philodendron 69686 is often confused with or compared to other deeply lobed or unusually shaped Philodendrons due to its complex morphology.
- Philodendron 69686: Characterized by highly variable, deeply lobed, sculptural leaves (hourglass, tri-lobed), which get very narrow in the center. It is an upright to semi-climbing Philodendron and is a relatively fast and vigorous grower.
- Philodendron joepii: This is the plant most commonly confused with P. 69686. P. joepii has distinctive tri-lobed leaves with two smaller lobes at the top aiming upwards and outwards at roughly a 45-degree angle, and a much more “insanely narrow” central constriction (waist) compared to P. 69686. P. joepii is also considered much rarer and slower growing.
- Philodendron mexicanum: Also has elongated leaves, but they are typically arrowhead-shaped with prominent basal lobes and often a reddish underside. While P. 69686 also narrows in the middle, it does so much more dramatically than P. mexicanum, and lacks the reddish underside.
- Philodendron pedatum: Features deeply lobed leaves with numerous finger-like segments, resembling an oak leaf or deer antler. While also complex, the lobing pattern is generally more uniform and less “hourglass” or “tri-lobed” than P. 69686. P. pedatum is also a climbing Philodendron.
The unique variability and often extreme narrowing in the center of its large, deeply lobed leaves are key distinguishing features of Philodendron 69686.

3.1. Light Requirements
Philodendron 69686 thrives in bright, indirect light, similar to the dappled sunlight it receives in its native rainforest habitat. 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 or north-facing windows are ideal for consistent soft light. For south or west-facing windows, use a sheer curtain to diffuse intense light or place the plant several feet away from the window. While it can adapt to lower light levels or partial shade, its variegation (if any subtle forms exist) will be more pronounced and growth will be faster in brighter conditions. Direct, harsh sunlight can easily scorch its leaves, leading to unsightly brown spots. Regularly rotating the plant ensures even light exposure and balanced growth.
3.2. Temperature and Humidity
As a plant from warm, humid climates, Philodendron 69686 prefers consistently warm temperatures, ideally ranging from 18-28°C (65-82°F). It’s crucial to protect it from sudden temperature drops or exposure to cold drafts (e.g., near open doors, air conditioners, or heating vents), as temperatures below 15°C (59°F) can stress the plant, slow growth, and cause leaf damage. Avoid extreme temperature fluctuations.
Philodendron 69686 prefers high humidity, ideally 60-80%. While it can adapt to typical indoor conditions (40-50%), it will thrive and produce better-looking leaves in higher moisture levels. Signs of insufficient humidity might include crispy brown leaf edges or tips, or new leaves struggling to unfurl properly and becoming distorted. You can increase humidity by using a room humidifier. Grouping the plant with other moisture-loving plants or placing its pot on a pebble tray filled with water (ensuring the pot itself doesn’t sit in the water) can also help create a more humid microclimate. Regular misting is also an option.
3.3. Watering Practices
Proper watering is critical for Philodendron 69686. It prefers its soil to be consistently moist but never soggy, allowing the top 1-2 inches (2.5-5 cm) or 3 cm of soil to dry out to the touch before watering again. Water thoroughly, ensuring 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. It’s generally safer to err on the side of underwatering than overwatering, as it can recover quickly from 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 weekly or every 1 to 2 weeks. During the cooler, dormant months of fall and winter, reduce watering frequency significantly, allowing the soil to dry out more thoroughly between waterings. Drooping or slightly wilted leaves can indicate underwatering, but the plant should recover quickly once watered.
3.4. Optimal Soil Mix and Repotting
A very airy, well-draining potting mix that dries out quickly is essential for Philodendron 69686. 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” or “chunky soil mix,” can include:
- High-quality potting soil (e.g., peat moss or coco coir)
- Large-chunk orchid bark
- Coarse-grade perlite or pumice
- Horticultural charcoal (optional, about 10% to remove toxicities)
Mixing equal parts of these components is a good starting point.
Repotting: Repot your Philodendron 69686 typically every 2-3 years, or when you notice it has become root-bound (roots growing out of drainage holes, roots crowding the top of the soil, or 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 one size larger (e.g., 1-2 inches larger in diameter) than the previous one, ensuring it has ample drainage. Avoid too much soil, as this can hinder its progress. Always replace the potting soil to prevent the build-up of pathogens. Be aware that plants may experience transplant shock, with the next 2-3 leaves after repotting potentially being small or deformed.
3.5. Fertilization Strategies
Philodendron 69686 is not an overly heavy feeder but benefits from regular fertilization during its active growing season (spring and summer) to support robust growth and leaf development.
- Frequency: Fertilize monthly or bi-monthly (every other month).
- Type & Dilution: Use a balanced liquid or water-soluble general houseplant fertilizer (e.g., 20-20-20 NPK) diluted to half the recommended strength. A fertilizer with a slightly higher nitrogen value (e.g., 3-2-1 or 5-2-3 NPK) can also be beneficial for foliage plants.
- Dormancy: Reduce or completely stop fertilizing during the fall and winter months when the plant’s growth naturally slows.
- Application: Always water the plant thoroughly before applying fertilizer to protect the roots from burn.
3.6. Pruning and Maintenance
Regular pruning is generally minimal for Philodendron 69686 due to its compact growth habit, but it is beneficial for maintaining shape and removing unhealthy foliage.
- Pruning: Remove any yellowing, brown, or damaged leaves as you see them using clean, sharp scissors or pruning shears. You can pinch off growing tips to encourage bushy growth. If you want to propagate, you can prune to control size or remove leggy growth during the growing season.
- Cleaning Leaves: Regularly dust the leaves with a damp cloth to allow maximum light absorption and photosynthesis. This also helps in keeping an eye out for pests.
- Support: Provide a moss pole, trellis, or other vertical support for its climbing habit. As it climbs higher, its leaves will typically get much larger. Train the aerial roots into the substrate or onto the pole early on.
4. Propagation Techniques: Expanding Your Collection
Propagating Philodendron 69686 is possible, primarily through stem cuttings. The best time for propagation is during the spring or early summer when the plant is actively growing. While some sources say propagation by stem cuttings is not recommended due to its compact habit and short stem, it is a common method that works with proper technique.
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 or aerial root emerges) 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 very 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 69686 can encounter a few common problems if its specific care requirements are not met. Prompt identification and action are crucial for maintaining its health.
Table 2: Common Problems & Troubleshooting for Philodendron 69686

|---|---|---|
| Yellowing Leaves | Older, lower leaves turning yellow. | Overwatering (most common), insufficient light, nutrient deficiency, natural aging. Adjust watering, fertilize, check roots for rot. |
| Brown Crispy Edges/Tips | Leaves browning and feeling crispy at edges. | Low humidity, underwatering, direct sun exposure. Increase humidity, adjust watering, move to indirect light. |
| Drooping/Wilted Leaves | Leaves losing turgor, looking limp. | Underwatering (most common), severe overwatering (root rot), cold shock. Check soil moisture, inspect roots, ensure warmth. |
| Stunted Growth/Less Defined Lobes | Slow growth, new leaves are smaller or lack typical complex lobing. | Insufficient light, nutrient deficiency, root-bound. Provide brighter light, fertilize, repot. |
| Leggy Growth | Long stems with sparse leaves. | Insufficient light. Move to brighter location. |
| Pest Infestations | Visible pests (spider mites, mealybugs), sticky residue, distorted growth. | Isolate plant, treat with insecticidal soap, neem oil, or appropriate pesticides. |
| Root Rot | Mushy stem base, black/brown, foul-smelling roots, yellowing/wilting. | Overwatering, poor drainage. Repot, trim rotten roots, improve drainage, reduce watering. |
| Leaves Losing Dark Color | Leaves turn lighter green or lose dark burgundy hues. | Can occur in very high light conditions. Adjust light to less extreme. |
5.1. Watering Issues
- Overwatering: This is a 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 1-2 inches (2.5-5 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, very well-draining soil. Reduce watering frequency, as it’s better to err on the side of underwatering.
- Underwatering: Symptoms include drooping or wilted leaves that may recover quickly once watered, and crispy brown edges or tips.
- 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, and leggy stems (long gaps between leaves on the stem as it stretches for light). The unique leaf shapes may also be less prominent.
- Solution: Move the plant to a location that receives bright, indirect light. Consider supplementing with a grow light (12-14 hours daily) if natural light levels are consistently low.
- Too Much Direct Light: Harsh direct sun can scorch the leaves, leading to brown, crispy patches or a faded appearance. In high light, leaves may turn more dark green, which for some, is less desirable than the dark burgundy color obtained in less extreme light conditions.
- 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: Can cause 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 (ideal for 60-80% RH). Grouping plants together or using a pebble tray can also help. Occasional misting is appreciated.
- Cold Stress: Exposure to temperatures below 15°C (59°F) can severely stress the plant, leading to leaf damage, wilting, and overall decline. It does not like chills.
- Solution: Ensure the plant is in a consistently warm environment (18-28°C is ideal) and protected from cold drafts from windows or air vents.
5.4. Pests
Common houseplant pests like spider mites and mealybugs can occasionally infest Philodendron 69686. Due to its bushy nature, pests can easily hide in cracks and crevices.
- Symptoms: Visible insects (mealybugs with white, cottony masses; spider mites with fine webbing), sticky residue (honeydew), or speckled, distorted leaves.
- Solution: Regularly inspect your plant, especially the undersides of leaves and inside the dense foliage where new growth emerges. Isolate infested plants immediately. Treat with appropriate organic pest control methods such as insecticidal soap or neem oil. 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, very well-draining aroid mix with good aeration, and adjust your watering schedule to allow the soil to dry adequately between waterings.
