Philodendron billietiae (Big)

This is a highly sought-after climbing Aroid, is prized for its long, strap-like, or elongated heart-shaped leaves. The plant's most distinctive feature is its bright orange-colored petioles (leaf stems), which create a striking contrast against the deep green foliage.

• Light: Requires bright, indirect light. Ample light is crucial for promoting the vibrant orange color of the petioles and enabling large leaf size. Avoid direct, harsh sun.
• Temperature: Thrives in warm, tropical conditions, ideally in the range of 65-85°F (18-29°C). It must be protected from cold and temperatures dropping below 60°F (16°C).
• Humidity: High humidity is necessary, with 60% or higher being beneficial for leaf health and size. Use a humidifier or other methods to increase ambient moisture.
• Watering: Water thoroughly, allowing the top 1 inch (2.5 cm) of the soil to dry out between applications. Use a chunky, well-draining mix to ensure the roots do not remain soggy.

Additional Notes

The intensity of the orange color is best maintained under strong, indirect light. The plant is considered toxic if ingested.
