Oncidium macranthum

This striking Andean orchid species is celebrated for its impressive large flowers and robust growth habit, making it an excellent choice for collectors seeking cool-growing orchids with dramatic blooms from high-elevation cloud forests.

• Light: Requires bright, filtered light without direct sunlight. Provide consistent lighting conditions to support healthy growth and robust flowering.
• Temperature: Thrives in cool to intermediate conditions with daytime temperatures of 59-72°F (15-22°C) and cooler nights of 50-59°F (10-15°C) to promote flowering cycles.
• Humidity: Demands moderate to high humidity levels of 60-80% with excellent air movement to replicate its natural cloud forest environment and prevent fungal issues.
• Watering: Water regularly during active growth, allowing the medium to approach dryness between waterings. Maintain consistent moisture year-round with slight reduction during cooler months.

Additional Notes

Produces spectacular branched inflorescences that can reach up to 4 meters in length, bearing substantial flowers that are among the largest in the genus Oncidium. This vigorous species creates a stunning cascading display when in full bloom.
