Anthurium Black Widow x Michelle is a hybrid sought-after for its unique and striking foliage, making it a popular addition to indoor plant collections.
Understanding Anthurium Black Widow x Michelle
Its leaves often display dark, almost black coloration, maturing to deep green. Young leaves emerge in shades of dark purple or burgundy. Foliage is typically heart-shaped and has a velvety texture, a trait from its ‘Michelle’ parent.
Intricate venation, often in contrasting lighter shades like white or pink, creates a striking pattern against the dark leaf surface. Some variations show unique vein patterns from the ‘Black Widow’ parent. The inflorescence, typical of anthuriums, consists of a spathe and spadix. While its primary appeal is the dramatic foliage, the spathe and spadix appearance varies among seedlings.
Optimal Growing Conditions
Light Requirements
Anthurium Black Widow x Michelle thrives in bright, indirect light. An east or west-facing window is ideal, providing ample light without direct sun. Direct sunlight, especially harsh midday sun, can scorch leaves. Lower light levels can slow growth and diminish leaf coloration. Filtered sunlight, such as through a sheer curtain, provides brightness without leaf burn.
Watering Practices
Proper watering is important. The plant prefers consistently moist, but not waterlogged, soil. Water thoroughly when the top 1 to 2 inches (2.5 to 5 cm) of potting mix feel dry. Good drainage is important; allow excess water to drain completely to prevent root rot. Conversely, prolonged complete drying can stress the plant.
Humidity and Temperature
This hybrid benefits from high humidity, typical of its tropical origin. Optimal humidity ranges between 60% and 85%. In drier indoor environments, use a humidifier, pebble tray, or group plants to maintain moisture. Consistent temperatures between 60°F and 85°F (15°C and 29°C) are suitable for growth. Protect the plant from cold drafts or sudden temperature fluctuations.
Potting Mix and Repotting
This anthurium requires a well-draining, airy potting mix, mimicking its natural epiphytic or hemiepiphytic growth. A suitable mix includes orchid bark, perlite, coco coir or chips, and some organic compost. This chunky composition ensures good root aeration and prevents water retention. Repot every one to two years, or when the plant becomes root-bound (roots growing out of drainage holes or circling tightly). When repotting, select a pot only slightly larger than the previous one, ensuring adequate drainage.
Fertilization
During its active growing season (spring and summer), this anthurium benefits from regular fertilization. A balanced liquid fertilizer, such as a 20-20-20 formula, applied at half strength once a month is recommended. Consistent feeding supports robust foliage and plant vigor. Reduce or cease fertilization during cooler winter months when growth slows. Periodically flush the soil with plain water to prevent mineral salt buildup.
Propagating Anthurium Black Widow x Michelle
Propagating this anthurium can be achieved through division or stem cuttings, especially if the plant has multiple growth points or a stem with aerial roots. For division, carefully remove the plant from its pot and gently separate the root ball into sections, ensuring each has roots and at least one growth point. Pot each new division into its own well-draining mix. This method creates larger, established plants quickly.
Stem cuttings can also be used, especially from a mature stem with aerial roots. Select a healthy stem section with at least one node and a few leaves, cutting cleanly below a node. Include aerial roots if present. Place the cutting in a propagation medium like sphagnum moss, perlite, or a mixture, ensuring high humidity for root development. A clear container helps monitor root growth. Consistent moisture and warmth are important for successful rooting, which can take several weeks.
Troubleshooting Common Issues
While generally resilient, this anthurium can show distress if environmental conditions are not met. Yellowing leaves often indicate overwatering, leading to soggy soil and root issues. Allow the soil to dry more thoroughly between waterings and ensure proper drainage. Yellowing can also suggest nutrient deficiency, remedied by diluted fertilizer.
Browning leaf tips or crispy edges indicate insufficient humidity, especially in dry indoor environments. Increase ambient humidity with humidifiers or pebble trays. Stunted growth can result from inadequate light or nutrient deficiencies. Adjust the plant’s location for more bright, indirect light and adhere to a regular fertilization schedule during the growing season for healthier development.
Pest infestations can occur, though anthuriums are not typically a primary target. Common pests include spider mites, mealybugs, and aphids. Symptoms like sticky residues, visible insects, or fine webbing suggest a pest problem. Regular inspection, especially of leaf undersides, allows early detection. Treatment involves wiping affected areas with a damp cloth or applying insecticidal soap or neem oil.
