Returns Simplified.Calathea Yellow Fusion is a truly mesmerising tropical houseplant celebrated for its vivid yellow marbling, painterly variegation, and living, moving foliage. A member of the Marantaceae family and native to the rainforests of South America, this rare cultivar is one of the most eye-catching Calatheas ever produced a masterpiece of colour and texture that feels almost otherworldly.
The long, lance-shaped leaves are a blend of lime-green, golden-yellow, and emerald brushstrokes, often with streaks of white that create a dynamic, swirling pattern. The undersides are a soft lavender-purple, which becomes visible each evening as the leaves fold upward in their characteristic nyctinastic prayer motion. Compact and delightfully unpredictable, every leaf of Calathea Yellow Fusion is unique, offering a vibrant burst of tropical artistry.
Dramatic yet elegant, Yellow Fusion brings an energising touch of the rainforest indoors a living work of art for collectors and design lovers alike.
Thrives in bright, indirect light, which enhances its striking variegation. Too much direct sunlight can fade the yellow tones or cause leaf burn, while too little light may dull its colours. East-facing windows or filtered daylight are ideal.
Keep the soil consistently moist but never soggy. Water when the top 23 cm of soil feels slightly dry, using filtered or rainwater to avoid fluoride and chlorine damage (which can cause leaf browning). Do not allow the soil to dry out completely. In winter, reduce watering frequency slightly but maintain humidity.
Temperature: Prefers warmth between 2028 C; avoid drafts and sudden temperature changes.
Humidity: Requires high humidity (6080%) to maintain leaf colour and prevent crisping. Mist regularly, use a humidifier, or place near other tropical plants to create a humid microclimate.
Use a light, moisture-retentive but well-draining mix, such as compost combined with perlite, coco coir, and a little orchid bark. This ensures airflow while holding steady moisture. Repot every 12 years in spring to refresh the soil and encourage strong root growth.
Feed every 46 weeks in spring and summer with a diluted, balanced liquid fertiliser or one formulated for foliage plants. Avoid over-fertilising, as the delicate variegated leaves are sensitive to nutrient build-up. Suspend feeding in autumn and winter.
Trim older, yellowing, or damaged leaves near the base to maintain a neat appearance and stimulate new growth. Wipe the leaves gently with a soft, damp cloth to remove dust and showcase their unique variegation. Rotate the plant occasionally for even light exposure and symmetrical growth.
A slow to moderate grower, Calathea Yellow Fusion typically reaches 3050 cm in height and spread indoors. Over time, it forms a dense cluster of foliage, each new leaf emerging with its own distinct colour pattern. Under the right conditions, it may also produce small, inconspicuous white flowers close to the base.
Brown leaf edges: Low humidity or use of hard tap water.
Faded colour: Insufficient light.
Curling leaves: Underwatering or low humidity.
Pests: Occasionally spider mites or thrips; treat promptly with neem oil or insecticidal soap while maintaining high humidity.
