Dendrobium atroviolaceum

Native to lowland rainforests of the southwestern Pacific, this Latouria-section orchid produces fragrant, heavy-textured flowers that remain attractive for an extended period. Its sculptural blooms make a distinctive addition to a warm orchid collection.

• Light: Bright, filtered light with gentle morning sun. An east-facing window or lightly shaded greenhouse position works well; protect from intense midday sun.
• Temperature: Warm-growing; aim for daytime temperatures of 75–85°F (24–29°C) and nights of 65–70°F (18–21°C). Avoid cold drafts and prolonged chilling.
• Humidity: Aim for 60–80% with steady, gentle air circulation, especially during warm weather.
• Watering: Water thoroughly and regularly during active growth, allowing an airy orchid mix to begin drying between waterings. Reduce watering and feeding slightly in winter if growth slows, but never allow prolonged complete dryness or impose a hard dry rest.

Additional Notes:

Yellow-green flowers have lightly spotted segments and prominent lips patterned with deep purple stripes. Thick, leathery leaves cluster near the tops of ridged, swollen canes. Retain healthy older canes, which can also flower, and grow in a snug, well-drained pot with an open bark-based mix.
