Philodendron ventricosum Madison

• Genus: Philodendron
• Botanical Background: Described by botanist Madison. While Philodendron ventricosum has not undergone significant taxonomic revision, it remains an important example of the diversity within the Philodendron genus.

• Geographical Range: Native to the tropical rainforests of South America, specifically found in Colombia and Ecuador, where it thrives at low to moderate altitudes.
• Environment: Thrives in humid, warm environments with stable temperatures and ample rainfall. In the wild, it grows in well-shaded areas, often near rivers and in the understory of tropical forests.

Leaves

• Large, elongated, and deeply lobed
• Glossy texture
• Color ranges from rich green to a darker shade
• Veins are pronounced

Inflorescence (Spadix & Spathe)

• Spadix is typical for the genus, bearing a creamy white to light yellow color
• Spathe is a greenish white

Growth Habit

• Epiphytic species
• Grows on trees and other surfaces in its native environment
• Uses aerial roots to anchor itself to supporting structures

Light Requirements

• Bright, indirect light
• Can tolerate lower light conditions

Watering & Humidity

• Consistently moist soil but not waterlogged
• High humidity levels (60% or above)
• Regular misting or the use of a humidifier can help
  

Soil & Potting Mix

• A well-draining, peat-based potting mix
• A mix that retains some moisture while allowing excess water to drain away

Temperature & Fertilizer

• Temperatures between 65-85°F (18-29°C)
• Fertilize monthly during the growing season
• A balanced, water-soluble fertilizer diluted to half strength

Division and Stem Cuttings

• Cutting stem sections that include at least one node
• Can be rooted in water or soil

Seeds

• Possible but not commonly practiced for this species due to the difficulty of obtaining seeds and the long germination time

Typical Issues

• Aphids, spider mites, and mealybugs
• Root rot

Treatment Recommendations

• Insecticidal soap or neem oil
• Ensure the plant has proper drainage
• Allow the soil to dry out between waterings
• Fungicide may be necessary

• Stunning foliage
• Used in traditional medicine in the regions where it is found

• Dramatic foliage and easy care
• Low-maintenance houseplant

Wild Population Status

• No significant conservation concerns
• Deforestation in its native regions could potentially impact its population

Market Availability

• May not be as widely available as some other Philodendron species
• Found in niche plant markets and among specialized collectors
