Returns Simplified.Alocasiazebrina Black Stem is a rare and dramatic tropical aroid, prized for its deeply pigmented black petioles and sleek arrow-shaped foliage. A darker, more mysterious variation of the classic Alocasia zebrina, this cultivar replaces the iconic striped stems with inky, near-black ones creating a bold monochrome contrast that exudes elegance and sophistication.
The leaves are glossy and arrowhead-shaped, with rich emerald-green tones and prominent venation. The smooth, dark stems elevate the leaves like sculptural displays, giving the plant an architectural, almost futuristic appearance. As it matures, Alocasia zebrina Black Stem develops a striking upright form, reaching 60100 cm in height, making it a perfect statement piece for contemporary interiors.
Sleek, minimal, and utterly captivating, Alocasia zebrina Black Stem combines the wild charm of the tropics with a modern, moody aesthetic a must-have for serious collectors and design-conscious plant enthusiasts.
Thrives in bright, indirect light. A few hours of soft morning or late-afternoon sun will promote strong growth and leaf colour. Avoid direct midday sunlight, which can scorch the leaves, and low light, which can cause smaller leaves and elongated stems.
Keep the soil consistently moist but never waterlogged. Water when the top 23 cm of soil feels dry. During the growing season (spring to summer), the plant appreciates regular watering; reduce frequency slightly in autumn and winter when growth slows. Always ensure good drainage.
Temperature: Prefers warmth between 2030 C; avoid temperatures below 16 C.
Humidity: Enjoys high humidity (6080%). Use a humidifier, mist occasionally, or group with other tropicals to maintain a moist environment. Low humidity may cause leaf edges to brown.
Use a light, airy, well-draining aroid mix, such as compost combined with orchid bark, perlite, and coco coir. This allows airflow while retaining gentle moisture. Repot every 12 years in spring to refresh the mix and accommodate growth. Choose a pot with drainage holes to prevent soggy roots.
Feed every 46 weeks during spring and summer with a diluted, balanced fertiliser or one designed for foliage plants. Suspend feeding during winter when growth naturally slows.
Remove older or yellowing leaves near the base to maintain the plants clean, upright appearance. Wipe the leaves gently with a damp cloth to remove dust and keep their glossy texture. Rotate the plant regularly for even light exposure and symmetrical growth.
A moderate grower, Alocasia zebrina Black Stem typically reaches 60100 cm tall indoors. Each new leaf emerges from the centre of the plant and unfurls into a perfect, glossy arrowhead supported by its distinctive dark petiole. With time and consistent care, it forms a compact clump of upright, elegant foliage that embodies tropical minimalism.
Yellowing leaves: Overwatering or cold exposure.
Brown tips: Low humidity or irregular watering.
Drooping leaves: Sudden temperature changes or overly dry soil.
Pests: Occasionally thrips, spider mites, or mealybugs; treat with neem oil or insecticidal soap.
Native to the rainforests of the Philippines and Borneo, Alocasia zebrina is a member of the Araceae family, renowned for its ornamental stems and lush foliage. The Black Stem cultivar is a rare variant that emphasises the plants architectural form by replacing the zebra-striped petioles with deep, near-black tones, creating a more refined and monochromatic look.
In cultivation, Alocasia zebrina Black Stem represents the darker side of tropical elegance bold, mysterious, and perfectly suited to modern interiors.
