Philodendron solimoesense A.C.Sm.

• Genus: Philodendron
• Botanical Background: Described by A.C. Smith, the species has been studied in the context of tropical flora diversity, contributing to a broader understanding of Amazonian plant life.

• Geographical Range: Native to the Amazon basin, this species thrives in the humid, tropical environments of South America
• Environment: Naturally found in lowland rainforests where high humidity, rich organic soils, and a warm climate support its growth; prefers shaded understories with filtered sunlight.

Leaves

• Large, ovate to heart-shaped
• With a glossy texture and deep green coloration
• Exhibit subtle venation patterns

Inflorescence (Spadix & Spathe)

• Produces a spadix surrounded by a protective spathe
• The spathe is typically greenish with hints of color, while the spadix is compact
• May emit a mild scent to attract specific pollinators

Growth Habit

• Primarily terrestrial, forming clumps via rhizomatous growth
• May occasionally climb if provided with support, adding versatility to its display

Light Requirements

• Thrives best in bright, indirect light
• Direct sunlight can scorch the leaves, while too little light may hinder growth

Watering & Humidity

• Regular watering is needed to maintain moist, well-draining soil
• High humidity levels are ideal
• Misting or placement near a humidifier can be beneficial

Soil & Potting Mix

• A well-draining, peat-based mix enriched with organic matter is recommended
• Container with drainage holes to prevent root rot

Temperature & Fertilizer

• Flourishes in temperatures between 65°F and 80°F
• Balanced, diluted fertilizer every 4-6 weeks

Division

• Most common propagation technique is through division of the rhizome

Stem Cuttings (if applicable)

• Node cuttings from established stems can also be used
• Provided they are kept in a warm, humid environment until roots develop

Seeds

• Less common due to variable germination rates; when attempted, seeds require warm, consistently moist conditions to sprout successfully

Typical Issues

• Spider mites, mealybugs, and aphids
• Root rot can occur if the plant is kept in overly wet conditions

Treatment Recommendations

• For pests, insecticidal soap or neem oil is effective
• Root rot can be prevented by ensuring the soil is well-draining and by allowing the top few centimeters of soil to dry out before re-watering

• Part of intricate ecological interactions, contributing to forest diversity
• Offering habitat to small invertebrates

• Prized for its bold, sculptural leaves and its ability to adapt to both indoor and shaded outdoor environments
• A favorite for modern tropical decor

Wild Population Status

• There is no immediate conservation concern for this species; however, habitat loss in the Amazon poses a long-term threat to its natural populations

Market Availability

• Moderately available in the horticultural trade
• High-quality specimens are sought after by dedicated collectors
