Expert careEpiphyteNon-toxic1–3 cm

Barbosella hirtzii is a micro-miniature epiphytic orchid from the cloud forests of Ecuador, growing at elevations around 2,450 m where cool temperatures and saturated humidity are constant. It belongs to the subtribe Pleurothallidinae (family Orchidaceae) and forms a tight creeping mat of small, fleshy, strap-like leaves rarely exceeding 2 cm in height — making it one of the smallest orchids suitable for vivarium use. It does best mounted on cork bark or in a shallow sphagnum mix inside a cool, humid closed enclosure; warm household temperatures above 22 °C will stress it. Single flowers, measuring roughly 2 cm, rise on slender peduncles well above the foliage and range from pale yellow-green to purple.

Distribution

Propagation

Divide established mats during repotting or remounting in spring. Separate sections of the creeping rhizome so each division carries at least one rooted stem and a leaf. Press divisions onto fresh cork bark backed with a thin layer of live or dried sphagnum, secure with soft ties, and keep in a cool, very humid environment with no direct air movement until new growth emerges — typically 6–10 weeks. Success rates are moderate when conditions are cold and stable; warm or dry conditions quickly lead to failure.
