-
Light: Bright indirect light to partial shade, similar to conditions under a 50-70% shade cloth. Avoid direct sunlight which can scorch the leaves.
-
Temperature: Cool grower - Days 55-68°F (13-20°C), Nights 45-55°F (7-13°C). Consistent cool temperatures are essential for healthy growth and flowering. A 10-15°F (5-8°C) day-night differential promotes blooming.
-
Humidity: 70-85% with constant air circulation to prevent fungal issues. Use humidity trays, room humidifiers, or terrarium culture to maintain adequate moisture levels. Good air movement is critical to prevent rot.
-
Watering: Keep consistently moist year-round but never waterlogged. Water frequency depends on mounting medium - mounted plants may need daily misting, potted plants every 2-3 days.
Additional Notes
Native to the cloud forests at elevations of 2,000-2,800 meters, this species is named in honor of Italian orchid enthusiast Alessandro D'Alessandro. Best grown in small pots with fine-grade bark mix or sphagnum moss, though it can also be mounted on tree fern or cork bark with regular watering.
