Oncidium Nerissa

A primary hybrid of Onc. naevium × Onc. alexandrae, producing upright spikes with large, elegant flowers. The elongated, narrow sepals and petals taper to sharp tips, while the broad trilobed lip features an undulate, finely fringed frontal lobe and prominent lateral column wings.

• Light: Bright indirect light with 40–60% shade cloth; avoid direct midday sun, which can stress the foliage and pseudobulbs.
• Temperature: 57–75°F (14–24°C); an intermediate grower that benefits from a slight nighttime temperature drop to encourage spike initiation.
• Humidity: 60–80%; 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 in a medium bark mix with good drainage and airflow around the roots. Plants are shipped bare root, well established, and ready to adapt quickly to their new growing environment.
