- Thick, sturdy stems add an architectural touch to interiors
- Rare and highly sought-after collector’s plant

🌞 Light & Placement
Thrives in bright, indirect light. Avoid direct midday sun to prevent leaf scorch. Ideal for east or north-facing windows, or a bright spot with filtered light.
💧 Water & Humidity
Keep soil evenly moist but not soggy. Loves high humidity (over 60%) – use a humidifier or place near other plants to boost ambient moisture.
🪴 Soil & Potting
Use a chunky, well-draining aroid mix with orchid bark, perlite, and coco coir. Repot every 1–2 years to support rapid rhizome growth.
🐾 Toxicity & Safety
Toxic if ingested. Keep out of reach of pets and small children.
🌱 Growth & Propagation
Grows from rhizomes that can be divided during repotting in spring. Each division should have at least one growth point for successful propagation.
📆 Seasonal & Special Care
May go semi-dormant in winter with slowed growth. Reduce watering accordingly and keep above 15°C to maintain foliage health.
🐛 Common Issues
Watch for spider mites and thrips, especially in dry conditions. Regularly wipe leaves to prevent dust build-up and pest hiding spots.
🧬 Botanical Background
Native to Southeast Asian rainforests, Alocasia cyrtosperma johnstonii ‘Black Jack’ is prized for its dark velvety foliage and compact yet dramatic form, making it a must-have for European Alocasia collectors.
