Oncidium spectatissimum
A spectacular epiphyte native to the cloud forests of Ecuador, producing arching spikes with large, boldly patterned flowers. The broadly spreading, lanceolate sepals and petals bear large, well-defined irregular spots on a pale ground, while the trilobed lip features a wide bilobed frontal lobe with a finely fringed margin and a prominent white central callus topped by a contrasting white column cap.
- Light: Bright indirect light with 50–65% shade cloth; avoid direct midday sun, which can stress the robust pseudobulbs and foliage.
- Temperature: 50–68°F (10–20°C); a cool grower that thrives with distinct seasonal temperature variation and consistent air movement.
- Humidity: 65–85%; high ambient moisture supports vigorous growth and the production of large, well-formed flowers.
- 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 medium bark mix with excellent drainage and good airflow around the roots. Plants are shipped bare root, well established, and ready to adapt quickly to their new growing environment.
