Oncidium abruptum

Native to Ecuador and neighboring northern Andean forests, this epiphytic orchid produces an airy display of flowers on long, branching stems. Its arching inflorescences make it a distinctive choice for a spacious botanical orchid collection.

• Light: Bright, filtered light near an east-facing window or under greenhouse shade. Protect from strong midday sun.
• Temperature: Intermediate conditions, ideally 65–80°F (18–27°C) during the day, with cooler nights of 55–65°F (13–18°C).
• Humidity: Aim for 60–80% humidity with steady air circulation.
• Watering: Water thoroughly during active growth, allowing the medium to approach dryness between waterings without remaining dry for long periods. Adjust frequency as growth slows, and always drain thoroughly.

Additional Notes:

Develops through successive pseudobulbs, with flower stems emerging from the base. Allow ample room for the long, branching inflorescences and support them loosely if needed. Repot as new roots emerge, using an airy orchid mix, and feed lightly during active growth.
