Monstera filamentosa Croat & Grayum

• Genus: Monstera
• Botanical Background: Described by botanists Thomas Croat and Michael Grayum, adding to the rich diversity of the Monstera genus; its discovery has provided additional insights into the evolution and adaptation strategies of aroids.

• Geographical Range: Native to the humid tropical forests of Central America, where it occupies the understory of dense, moist woodlands.
• Environment: Warm, humid conditions with indirect light; prefers well-drained, organically rich soils and benefits from the filtered light found on the forest floor, sometimes growing as an epiphyte on larger trees.

Leaves

• Broad with a textured surface
• Intricate perforations
• Unique filamentous extensions along the petioles 

Inflorescence (Spadix & Spathe)

• Compact spadix, surrounded by a protective spathe

Growth Habit

• Exhibits a climbing or vining habit
• Develops a robust rhizome system

Light Requirements

• Bright, indirect light

Watering & Humidity

• Regular watering with good drainage
• High humidity
• Periodic misting or placement in a humid room

Soil & Potting Mix

• A loose, well-aerated potting mix enriched with organic matter
• A container with drainage holes

Temperature & Fertilizer

• Temperature range is between 65°F and 80°F
• Feeding with a balanced liquid fertilizer during the growing season

Division and Stem Cuttings

• Most common propagation method is by node cuttings or by dividing sections of the rhizome
• Cutting should include at least one active node

Seeds

• Less common due to variable germination rates
• Reserved for controlled research purposes rather than routine cultivation

Typical Issues

• Spider mites, aphids, and mealybugs
• Root rot 

Treatment Recommendations

Wild Population Status

• Wild population is limited
• Habitat is under pressure from environmental changes
