Philodendron applanatum G.M.Barroso

• Genus: Philodendron
• Botanical Background: Described by botanist G.M. Barroso, whose contributions have been significant in cataloging Brazilian aroids; its formal description has added valuable insights into the diversity and evolutionary relationships within the Philodendron genus.

• Geographical Range: Found in areas with dense, humid forest canopies, potentially including parts of Brazil’s diverse ecosystems in the native to tropical regions in South America.
• Environment: Thrives in warm, humid conditions and favors well-drained, organically rich soils and environments where filtered light mimics the dappled conditions of a rainforest understory.

Leaves

• Large, heart-shaped leaves
• Glossy and leathery
• Subtle yet appealing texture
• Coloration is a uniform deep green

Inflorescence (Spadix & Spathe)

• Spathe is modestly colored with hints of green and cream
• Scent is minimal but serves as an attractant for specialized pollinators

Growth Habit

• Primarily a terrestrial plant but also exhibits characteristics of a semi-epiphyte
• Develops a creeping rhizome that enables it to spread along the forest floor or cling to supports

Light Requirements

• Bright, indirect light, which replicates the filtered sunlight of its native forest understory
• Direct sunlight should be avoided to prevent leaf scorch

Watering & Humidity

• Ensure that the soil remains consistently moist but never waterlogged
• Benefits from high humidity

Soil & Potting Mix

• Use a well-aerated, organically rich potting medium such as a mix of peat and perlite
• Substrate should offer excellent drainage while retaining enough moisture

Temperature & Fertilizer

• Ideal temperature ranges between 65°F and 80°F
• Balanced, diluted fertilizer applied during the growing season

Division and Cuttings

• Most reliable propagation method is through division of its rhizomes or node cuttings
• Should be performed during the active growing period

Seeds

• Less common for home growers due to inconsistent germination; require warm, humid conditions to sprout and develop

Typical Issues

• Infestations by spider mites and mealybugs
• Occasional fungal infections such as root rot in overwatered conditions

Treatment Recommendations

• Insecticidal soap and appropriate organic fungicides
• Maintaining proper watering techniques and ensure good air circulation

• Captivates enthusiasts with its unusual, flattened leaf structure and elegant inflorescence
• Discovery has enriched our understanding of tropical aroid diversity

• Treasured for its rarity and distinctive aesthetic
• Serves as a conversation piece among collectors
• Popular choice for those seeking to bring a touch of the tropics into cultivated collections

Wild Population Status

• There is concern that habitat loss due to deforestation may impact wild populations of this species

Market Availability

• Available through specialized dealers and plant societies
