Named in honor of Thien, this is one of the few warm-tolerant species in the genus, making it an accessible choice for growers who cannot maintain the cool conditions required by most Masdevallias. Its intermediate-warm temperature range opens the door to a wider range of growing environments without sacrificing the refined floral character of the genus.

• Light: Grow under 50–70% shade cloth; direct sun causes rapid damage to its fine foliage and must be avoided.
• Temperature: Intermediate-Warm grower. Daytime 62–78°F (17–26°C), nights 52–62°F (11–17°C). One of the more heat-tolerant species in the genus.
• Humidity: Requires 75–90% relative humidity; its fine root system benefits greatly from a humidifier with steady air movement to prevent desiccation.
• Watering: Keep evenly and consistently moist; best grown mounted or in a small pot with fine bark to allow the roots to dry slightly between waterings, with more frequent misting during warmer months.

Additional Notes

Grown at Ecuagenera under intermediate-warm conditions. Plants are shipped bare root, well-established, and ready to mount or pot in fine bark or sphagnum moss.
