Bulbophyllum lobbii is a medium sized, warm‑to‑hot growing epiphytic orchid native to lowland and montane rainforests across Southeast Asia. It forms well‑spaced, egg‑shaped pseudobulbs (~3–5 cm long) along a creeping rhizome, each topped with a single, leathery, elliptical leaf (up to ~25 cm long). In summer, each new pseudobulb sends up a 15 cm erect inflorescence bearing a single large, fragrant flower (~7–10 cm across), typically yellow to buffalo‑yellow with olive‑green tones and sprinkled with purple, pink or reddish‑brown spots, with a slightly curved, hinged lip .
Native to:
Southeast Asia: Assam (India), Myanmar, Thailand, peninsular Malaysia, Borneo (Sabah), Sumatra, Java, Luzon and Palawan in the Philippines, at elevations from ~200 m to 2 000 m in lowland and montane rainforests. It grows as an epiphyte on tree trunks and main branches.
Water:
Keep the potting medium moist but not waterlogged. Avoid allowing the mix to dry out completely. In winter, reduce watering slightly so the medium is only just moist.
Light:
Provide bright, filtered light—similar to an east‑ or north‑facing window or beneath diffuse cover of a south window. Avoid strong direct sun, especially midday.
Humidity:
Maintain humidity around 75–80%. Good air circulation is essential to prevent fungal issues.
Temperature:
Daytime: ~24–26 °C (warm). Nighttime drop to ~14–15 °C in cooler periods; generally keep above 15 °C (avoid below ~15 °C). A diurnal range of ~9–11 °C encourages prolific budding
