Key Features:

Size:  Compact and slow-growing, ideal for indoor spaces with limited room. Grows more rapidly in warm summer months, but may enter dormancy during winter months.

Pet-Friendliness

Toxic to pets – Contains calcium oxalate crystals which can be harmful if ingested by cats or dogs. Keep out of reach of pets and children.

Care Instructions

Light: Prefers bright, indirect light. Avoid harsh direct sunlight, which may scorch the leaves. Too little light can reduce vibrancy and slow growth.

Watering: Keep the soil evenly moist but never soggy. Allow the top 1–2 inches to dry between waterings. Water less often in winter when growth slows.

Humidity: Thrives in high humidity (60%+). Use a humidifier, pebble tray, or mist lightly to mimic its native tropical environment.

Temperature: Maintain warm temperatures between 18°C–27°C. Protect from drafts and avoid letting it drop below 15°C.

Soil: Use a loose, well-draining mix such as an aroid blend containing orchid bark, perlite, and coco coir.

Fertilizer: Feed once a month during spring and summer with a balanced liquid fertilizer diluted to half strength. Do not fertilize in fall and winter.

Pruning: Remove any yellow, damaged, or older leaves at the base to encourage new growth and keep the plant looking its best.

Repotting: Repot every 1–2 years or when root-bound. Choose a pot with proper drainage to prevent root rot.
