This is a hybrid between Bulb. cumingii and Bulb. mastersianum. As a tropical epiphyte, it is best grown in conditions that simulate a warm, humid, and shaded environment, ideal for mounting or shallow pots.
-
Light: Requires moderate to bright indirect light, similar to Cattleya light levels, but must be shielded from strong, direct sun which can damage the leaves.
-
Temperature: Cultivate as an intermediate to warm grower, with ideal daytime temperatures between 68-86°F (20-30°C) and a slight drop of 10-14°F (6-8°C) at night to encourage flowering.
-
Humidity: Needs high humidity, maintaining levels between 60% and 70% or higher, coupled with excellent air circulation to prevent leaf issues.
-
Watering: Water frequently and liberally during active growth to keep the well-draining medium consistently moist, but ensure it never becomes waterlogged due to its fine root system.
Additional Notes
As a hybrid, this plant typically produces vibrant flowers, often in shades of yellow to orange. It is characterized by its rhizomatous growth and fine roots, making well-draining media like fine bark, charcoal, or sphagnum moss essential.
