Philodendron alatisulcatum Croat

• Genus: Philodendron
• Botanical Background: Described by Thomas Croat, the species reflects decades of botanical exploration within tropical floras and its classification has been refined through careful morphological and genetic studies that emphasize the diversity found among philodendrons.

• Geographical Range: Found in regions of high humidity and steady moisture in the native to the tropical lowland and submontane rainforests of parts of Central and South America.
• Environment: Thrives in warm, humid conditions with well-draining soils rich in organic matter and often grows in sheltered forest understories with diffused light, consistent moisture, and moderate temperatures.

Leaves

• Broad, exhibiting a robust, leathery texture
• Deep green color
• Marked venation

Inflorescence (Spadix & Spathe)

• Spathe is modest in size
• Greenish with subtle hints of color
• Not highly scented, it plays a role in attracting specific pollinators

Growth Habit

• Terrestrial but can exhibit an epiphytic tendency
• Develops a robust rhizome
• Resilient in humid conditions

Light Requirements

• Thrives in bright, indirect light
• direct sunlight may scorch the leaves

Watering & Humidity

• Requires consistent moisture without waterlogging
• Benefits from high humidity
• Regular misting or placement in a humid environment

Soil & Potting Mix

• Prefers a loose, well-draining potting mix enriched with organic matte

Temperature & Fertilizer

• Optimal temperatures range between 65°F and 80°F (18°C–27°C)
• Balanced, water-soluble fertilizer during the active growing season
• Reduce feeding in the winter months

Division

• Through rhizome division

Stem Cuttings (if applicable)

• Stem cuttings taken at a node, ensure a portion of the underlying rhizome is included

Seeds

• Rarely practiced due to low viability and slow germination rates in controlled cultivation

Typical Issues

• Spider mites and mealybugs
• Overwatering may lead to fungal issues like root rot

Treatment Recommendations

• Infestations can be managed with insecticidal soap or neem oil
• Ensure proper drainage as its critical to preventing root rot

• Noted not only for its striking leaf texture but also for its rarity, which can lend an air of exclusivity in private collections

• Unique foliage and moderate size make it an attractive choice for indoor cultivation
• Often used as a statement plant in modern and tropical-inspired interior designs

Wild Population Status

• Not currently listed as endangered, habitat loss in tropical regions is a concern

Market Availability

• Rare in the horticultural trade
• Available through specialist collectors
• May demand higher prices due to its limited distribution
