Pleurothallis kelsoae

Pleurothallis kelsoae is a miniature epiphytic orchid native to Ecuador, prized for its compact growth habit, delicate foliage, and successive small blooms. This species thrives in cool to intermediate conditions, making it well-suited for terrariums, orchidariums, and mounted vivarium culture.

Best grown mounted on cork or tree fern with a moisture-retentive moss layer, it prefers bright, filtered light and consistently high humidity with strong airflow. Temperatures between 57–72°F (14–22°C) are ideal. Plants should remain evenly moist and never be allowed to fully dry out, as the species is sensitive to dehydration.

When potted, a fine-grade orchid mix designed for miniature epiphytes works best. Under proper conditions, Pleurothallis kelsoae produces small, elegant flowers (pic 2) from reclining spathaceous bracts over extended periods.

Care Requirements

Light: Bright, filtered light, under terrarium LEDs growth is great. 

Humidity: 60–80% with good air circulation is ideal but we have kept these mounted on Manzanita up to 90% humidity with no issues at all. 

Temperature: Cool to intermediate (57–72°F / 14–22°C), but up to 78 is fine periodically. 

Watering: Keep consistently moist; avoid complete drying

Growth Habit: Miniature epiphytic orchid ideal for mounted culture or high-humidity terrariums
