Dendrobium cuthbertsonii 'Martina'

This miniature, cool-growing epiphytic orchid is native to the New Guinea highlands. The species is famed for its large, long-lasting flowers relative to the plant's size. The 'Martina' clone is selected for its desirable large flowers in white to soft pink shades.

• Light: Requires bright, indirect light, which is crucial for flowering. Protect it from direct, intense sun that can burn the fleshy leaves.
• Temperature: A cool-growing species demanding consistently cool temperatures. Maintain daytime temperatures between 72-77°F (22-25°C), with cool nights between 50-54°F (10-12°C) to encourage blooming.
• Humidity: Crucially requires very high humidity, ideally 80% or more, year-round. Strong, constant air movement is essential to prevent fungal issues.
• Watering: Water consistently and heavily throughout the year, as the potting medium must never dry out completely. This orchid is best grown mounted or potted in sphagnum moss to ensure constant moisture.

Additional Notes

The 'Martina' clone is noted for its oversized flowers, which can measure 1" (2.5cm) wide. The waxy, white-to-pink flowers appear on short, stocky stems and offer an outstanding contrast to the dark foliage. Each flower has an exceptional lifespan, often lasting for many months on the plant.
