• Genus: Philodendron
• Botanical Background: Described by botanist Thomas B. Croat, this species was named after the Australian botanist W. Davidson, who contributed to the early research of tropical plants. The species was identified in the late 20th century and remains an important subject for taxonomists studying Philodendron diversity.

• Geographical Range: Found in the rainforests of Panama and Colombia, thriving in the lowland to mid-elevation tropical ecosystems of these regions.
• Environment: Flourishes in humid, shaded environments with moderate rainfall; it prefers rich, well-draining soils and typically grows at high humidity levels, around 70-90%, in warm tropical climates with consistent temperatures.

Leaves

• Large, glossy, and deep green
• Often exhibiting a smooth texture with slight undulations along the margins
• Can reach up to 60 cm in length and are ovate to lance-shaped

Inflorescence (Spadix & Spathe)

• Consists of a typical Philodendron spathe and spadix, with the spathe often being white or pale green
• The spadix may produce a slight fragrance, aiding in pollination by insects
• The pollination mechanism is typical of aroids, relying on heat and scent to attract pollinators

Growth Habit

• Primarily epiphytic but can also grow terrestrially in its native habitat
• Has a climbing growth habit, using aerial roots to anchor itself to nearby structures or trees
• Can also spread via rhizomes

Light Requirements

• Thrives in bright, indirect light but can tolerate lower light conditions
• Direct sunlight should be avoided as it can scorch the leaves

Watering & Humidity

• Requires regular watering, ensuring that the soil is kept evenly moist but not waterlogged
• High humidity is essential, ideally above 60%

Soil & Potting Mix

• A well-draining, airy potting mix is ideal
• A blend of peat, perlite, and orchid bark ensures good drainage and supports the species' climbing nature
• Containers should allow for proper root expansion
  

Temperature & Fertilizer

• Optimal temperature range for this species is between 18°C and 28°C (65°F to 82°F)
• Balanced liquid fertilizer can be applied every 4-6 weeks

Division

• Rhizome division can also be used to propagate mature plants

Stem Cuttings (if applicable)

• Can be propagated by stem cuttings
• Ensuring that each cutting includes a node

Seeds

• Common but possible, requiring warm conditions and a humid environment for germination
• Typically not available in the commercial market

Typical Issues

• Spider mites, mealybugs, and aphids
• Root rot may occur if the plant is overwatered or in poorly draining soil

Treatment Recommendations

• Use insecticidal soap or neem oil for pest management
• For root rot, remove affected roots and repot the plant in fresh, well-draining soil
• Ensure that containers have adequate drainage to prevent future issues
  

• Plays a role in the local ecosystem as an epiphyte, providing shelter and food for various insects
• Has a strong cultural presence in the ornamental plant trade for its striking foliage

• Prized for its large, glossy leaves and is a popular choice among collectors
• Climbing nature also makes it an excellent candidate for creating vertical garden displays or as an ornamental feature in larger plant arrangements

Wild Population Status

• Not considered endangered, but habitat destruction in parts of its native range poses a potential threat

Market Availability

• Not widely available in commercial nurseries
• Can be found in specialty aroid collections and among dedicated plant enthusiasts
