Bulbophyllum auratum

In its native habitat, B. auratum grows as an epiphyte on trees across Borneo (Kalimantan, Sabah, Sarawak, Brunei), Malaysian Peninsular regions like Pahang and Terengganu, Thailand, Sumatra, and the Philippines, typically at 1001,200m altitude. Its growth is characterised by a creeping rhizome with dark olivegreen, grooved ovoid pseudobulbs (~12cm apart), each topped by a single purplish, blunttipped leaf.

Flowering occurs from spring through summer (and sometimes twice annually), producing a slender, purplish inflorescence up to ~15cm long that bears a drooping umbel of shoeshaped flowers (~3.5cm wide). These are pale yellow with scarlet or pink veins/spots, with fringed sepal edges and long hairlike tips, and a dark scarlet lip.

Native to:
Southeast AsiaBorneo (Kalimantan, Sabah, Sarawak, Brunei), Peninsular Malaysia (Pahang, Terengganu), Thailand, Sumatra, and the Philippines (Western Visayas), growing as an epiphyte at 1001,200m. Mature growth presents single apical purplish leaves atop olivegreen pseudobulbs with a creeping rhizome.

Water:
Maintain a wetdry cyclewater abundantly during active growth in warmer months, allowing the media to approach dryness before watering again.Use a freedraining mix (e.g., bark, sphagnum, perlite) or mount on cork or treefern slabs. Keep damp but never soggy; reduce watering gradually in autumn and winter, but do not let the plant dry out completely.

Light:
Provide bright, filtered light. Avoid direct midday sun; ensure good air movement.

Humidity:
Maintain around 7580% relative humidity.B. auratum is wellsuited for terrarium cultivationespecially as the plant remains small.

Temperature:
Ideal daytime temperatures between 2026C and nighttime down to 1617C (89C diurnal variation). Intermediatewarm conditions yearround are ideal.
