A floriferous hybrid of Onc. cheirophorum × Onc. sotoanum, producing arching, well-branched spikes densely set with numerous small, sweetly fragrant flowers clustered along secondary branches. The ovate sepals and petals have a smooth texture with a gently undulate margin, while the compact trilobed lip features a rounded frontal lobe and a contrasting central callus.
-
Light: Bright indirect light with 40–60% shade cloth; avoid direct midday sun, which can stress the compact pseudobulbs and foliage.
-
Temperature: 57–75°F (14–24°C); an intermediate grower that benefits from a slight nighttime temperature drop to encourage spike initiation and enhance fragrance.
-
Humidity: 60–80%; consistent moisture supports vigorous growth and the production of densely flowered, fragrant spikes.
-
Watering: Water thoroughly and allow the medium to approach dryness between waterings; never allow roots to sit in standing water.
Additional Notes
Best grown in a fine bark mix with good drainage and airflow. Plants are shipped bare root, well established, and ready to adapt quickly to their new growing environment.
