Oncidium tenuifolium

A distinctive epiphyte from the cloud forests of South America, producing slender spikes with medium-sized, star-shaped flowers of striking architectural form. The very elongated, linear-lanceolate sepals and petals taper to sharp tips with a slightly glossy texture, while the compact trilobed lip features a narrow frontal lobe and a 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 slender pseudobulbs and fine foliage.
• Temperature: 57–75°F (14–24°C); an intermediate grower that appreciates stable temperatures with a slight nighttime drop to encourage spike initiation.
• Humidity: 65–80%; consistent moisture supports healthy growth and reliable 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 fine bark mix with good drainage and airflow to suit its slender root system. Plants are shipped bare root, well established, and ready to adapt quickly to their new growing environment.
