Philodendron subincisum Schott

• Genus: Philodendron
• Botanical Background: Described by the influential botanist Schott, this species has intrigued experts with its distinct morphology. Historical records emphasize its role in expanding understanding of aroid diversity in tropical ecosystems.

• Geographical Range: Native to the tropical rainforests of South America
• Environment: Thrives in humid conditions with abundant indirect light; grows in well-draining, organically rich soils under the filtered canopy of tropical forests.

Leaves

• Deep lobes that create an almost architectural silhouette
• Glossy with a vibrant medium green hue

Inflorescence (Spadix & Spathe)

• Spadix and accompanying spathe
• Modestly sized and typically light in tone, and while not heavily scented, it plays a role in attracting specialized pollinator

Growth Habit

• Climbing plant that frequently uses aerial roots to anchor itself as it ascends supporting structure
• Develops a robust rhizome, ensuring persistence and regrowth in its natural habitat

Light Requirements

• Bright but indirect light
• Direct sunlight can scorch the leaves, while low light may reduce the leaf’s dramatic appearance

Watering & Humidity

• Maintain a consistently moist substrate while avoiding waterlogging
• High humidity benefits the plant, so regular misting or placement in a humid area is advisable

Soil & Potting Mix

• A well-draining, aerated potting mix enriched with organic matter works best
• A container that allows excess water to escape helps prevent root rot

Temperature & Fertilizer

• Ideal temperature ranges between 65°F and 80°F
• A balanced liquid fertilizer during the growing season to support steady growth

Division and Cuttings

• Most successfully achieved through stem node cuttings or division of the rhizome

Seeds

• Rarely practiced due to lower germination rates and a longer period to reach a displayable size

Typical Issues

• Spider mites and mealybug
• Overwatering can lead to root rot

Treatment Recommendations

• Insecticidal soap or neem oil can be effective for control
• Adjust watering routines and ensure proper drainage to manage fungal diseases

• The deeply incised leaves not only provide aesthetic appeal but also contribute to the plant’s efficient light capture in its shaded native habit
• Vigorous climbing nature is both a survival adaptation and a point of horticultural interest

• Prized this species for its unusual leaf design and architectural form, making it a standout specimen in any aroid collection or modern interior setting

Wild Population Status

• Not currently listed as endangered, habitat loss through deforestation remains a concern for the species’ natural populations

Market Availability

• Moderately available in specialist nurseries and among aroid enthusiasts
