Coryanthes macrantha x Stanhopea candida

This intergeneric cross brings together Coryanthes macrantha and Stanhopea candida, offering an intriguing project for collectors interested in unusual orchid breeding. The offspring's flower color and form should be evaluated at flowering rather than assumed from either parent.

• Light: Bright, filtered light in a shaded greenhouse or near an east-facing window. Avoid strong direct sunlight.
• Temperature: Intermediate to warm-growing conditions are a suitable starting point, ideally 70–85°F (21–29°C) during the day and 60–70°F (16–21°C) at night. Adjust conditions according to the plant's response.
• Humidity: Aim for 65–85% humidity with steady, gentle air circulation.
• Watering: Keep the medium evenly moist during active growth without allowing it to become waterlogged. Use rainwater or low-mineral water and an airy, moisture-retentive orchid mix. Adjust watering to temperature and root activity, avoiding prolonged dryness.

Additional Notes:

An open hanging basket provides room for downward-developing inflorescences associated with both parent genera. Keep the basket lining light enough for emerging spikes to pass through, and leave clear space beneath it. Repot when fresh roots begin to emerge, minimizing disturbance to established roots.
