Oncidium sergii

A slender miniature epiphyte native to the cloud forests of Ecuador, producing thin, arching spikes with a few small flowers well spaced along the rachis. The narrow, linear-lanceolate sepals and petals taper to sharp tips and have a smooth texture, while the compact trilobed lip features reduced lateral lobes, a narrow frontal lobe, and a dark-spotted basal callus flanked by a short, visible column.

• Light: Bright indirect light with 50–60% shade cloth; avoid direct sun, which can stress the delicate miniature growth.
• Temperature: 57–75°F (14–24°C); an intermediate grower that appreciates stable temperatures with a slight nighttime drop.
• Humidity: 65–80%; high ambient moisture supports the fine root system and encourages consistent flowering.
• Watering: Water thoroughly and allow the medium to approach dryness between waterings; never allow roots to sit in standing water.

Additional Notes

Best grown mounted on cork or in a very fine bark mix to suit its compact root system. Plants are shipped bare root, well established, and ready to adapt quickly to their new growing environment.
