Masdevallia calocalix

This striking Ecuadorian species produces distinctive tubular flowers with fused sepals forming an elegant cup-like structure, displaying vibrant orange to red-orange coloration. The compact growth habit and sequential blooming make it an excellent choice for cool greenhouse collections.

• Light: Bright shade to filtered light, avoiding direct sun which can burn the foliage; east-facing windows or 50-70% shade cloth recommended
• Temperature: Cool grower - 50-68°F (10-20°C) days, 45-55°F (7-13°C) nights; benefits from consistent cool conditions year-round with good day-night temperature differential
• Humidity: 70-85% with excellent air circulation to prevent fungal issues; use fans or natural airflow, mist in morning hours during dry periods
• Watering: Keep consistently moist year-round using pure water (rainwater or RO preferred), reduce frequency slightly in winter but never allow to dry completely; water in morning to allow foliage to dry before evening

Additional Notes

Native to the cloud forests at elevations of 2,000-3,000 meters, this species is prized for its unique calyx-like flower form that gives it its name. Best grown mounted on tree fern or cork bark, or in small pots with fine-grade bark mix or sphagnum moss to accommodate its compact root system.
