Bulbophyllum treschii is a miniature epiphytic orchid species native to Malaysia. It produces small ovoid pseudobulbs spaced along a creeping rhizome, each topped with a single erect leaf. The inflorescences are typically 4–9 cm long and bear several (6–9) simultaneously-opening flowers, showing an unusual and intricate structure. The colouration and form vary somewhat, but many blooms carry dark purple markings over white or pale ground. The species has become a favourite among mini-orchid enthusiasts for its compact size and distinctive flowers.

Short Care Guide

• Light: Bright, indirect light. Avoid strong direct sunlight – morning filtered light or a shaded east window works well.

• Temperature: Intermediate to warm-cool conditions: daytime around 21-28 °C (70-82 °F), nighttime not below about 15-16 °C (59-61 °F).

• Humidity & Airflow: High humidity (ideally ~70 % or more) with good air circulation to keep the leaves and rhizome healthy and to avoid rot.

• Watering: Keep the growing medium consistently moist but never water-logged. Because it is epiphytic, it appreciates frequent moisture and good drainage/mounting.

• Medium / Mounting: Best grown mounted on cork or tree-fern with a bit of sphagnum moss around the roots, or in a very open, moist potting mix (fine bark + moss) that allows quick drying of the outer layer between waterings.

• Fertilising: Use a diluted balanced orchid fertilizer (¼ strength) during active growth. Flush occasionally to prevent salt build-up.

• Blooming Notes: Being a compact species, good cultural conditions (moisture, humidity, stable temps) help encourage the characteristically short but showy inflorescences.
