Care Guide

• Light: Bright, indirect light. Tolerates some shade but thrives with good light. Avoid prolonged direct sun which can scorch its large, dramatic leaves.
• Water: Loves moisture — keep soil consistently moist to wet. Unlike most aroids, this one appreciates consistently damp conditions. Don’t let it dry out completely.
• Humidity: High humidity is essential (60%+). Native to tropical swampy environments, it craves a humid atmosphere — a humidifier is highly recommended.
• Temperature: Warm conditions year-round — prefers 65–90°F (18–32°C). Very cold-sensitive; keep away from drafts and anything below 60°F.
• Soil: Rich, moisture-retentive mix. A blend of potting soil, coco coir, and perlite works well — unlike most aroids, you want this one to stay moist.
• Fertilizer: Feed monthly during the growing season with a balanced liquid fertilizer. A large, hungry plant that benefits from regular feeding.
• Size: This is a true statement plant — it can grow very large with enormous leaves. Give it space to spread and shine!
• Repotting: Move up pot sizes gradually as needed when rootbound.

⚠️ Toxicity Warning: Contains calcium oxalate crystals — toxic to pets and humans if ingested. Keep out of reach of children and animals.
