Oncidium hallii xanthinum

A select variety of a robust species from the cloud forests of South America, producing arching, branched spikes with medium-sized flowers of a distinctly spidery habit. The narrow, elongated, and strongly reflexed sepals and petals curve at their tips and bear fine, scattered spotting, while the trilobed lip displays a fimbriate frontal lobe and a neat yellow callus.

• Light: Bright indirect light with 40–60% shade cloth; avoid direct sun, which can scorch the strap-like foliage.
• Temperature: 55–75°F (13–24°C); an intermediate to cool grower that benefits from a nighttime temperature drop to encourage blooming.
• Humidity: 65–85%; good air circulation is essential to prevent fungal issues at higher humidity levels.
• Watering: Water thoroughly and allow the medium to approach dryness between waterings; never allow roots to sit in standing water.

Additional Notes

Best cultivated in a fine bark or sphagnum moss mix in a well-draining container or mounted on cork. Plants are shipped bare root and well established.
