About Trichoglottis brachiata

Trichoglottis brachiata · also called Hairy-tongued Orchid, Philippine Trichoglottis · tropical

Trichoglottis brachiata is a warm-growing, monopodial epiphytic orchid from Philippine lowland forests, producing waxy, star-shaped flowers heavily marked maroon over a paler base. It climbs steadily on a single leafy stem with abundant aerial roots, thriving in constant warmth, high humidity and bright filtered light, and is best grown mounted or in an open basket.

Preferred mix: Mounted on cork/treefern, or in a very open coarse-bark basket

Watch for — Stem and root rot: Stagnant moisture and poor airflow rot the climbing stem. Keep roots exposed or in open mix with strong air movement and let them dry between waterings.
