Microcoelia gilpiniae

Microcoelia gilpiniae is a captivating, leafless epiphytic orchid endemic to Madagascar. Its striking orange blooms contrast beautifully with its silvery, photosynthetic roots. This species grows in mossy, humid forests and occasionally in disturbed vegetation at elevations of 100–1,800 m.

Features:

• Leafless: Photosynthesis occurs via chlorophyll-rich roots

• Pseudobulbs: Very short or absent stem, with many slender, often twisted, roots

• Flowers: Small (~1.1–1.3 cm), densely arranged on basal inflorescences bearing 10–12 flowers, blooming in spring through fall; typically unscented

Care Tips:

Mounting & Medium

• Best grown mounted on cork, tree fern slabs, or similar surfaces. Minimal moisture-retaining material should be used around roots.

Watering & Humidity

• Keep roots moist, especially during warm periods—water daily when warm, reduce frequency in cooler seasons.

• Maintain high humidity at all times to prevent root desiccation.

Light & Temperature

• Roots may tolerate bright light thanks to their velamen, but shade during hot weather helps avoid overheating.

• Growers report it's forgiving across a wide temperature range—from about 40°F (4°C) in winter to 85°F (29°C) in summer—provided humidity is sufficient.

Air Circulation

• Ensure gentle airflow to prevent rot and mold on the delicate, exposed roots.
