Restrepia trichoglossa · also called Hairy-tongued Restrepia · tropical

Restrepia trichoglossa is a diminutive Andean epiphytic orchid distinguished by its lip adorned with tiny hair-like papillae — the feature behind its common name. Native to Colombia and Ecuador, it produces colorful striped flowers repeatedly throughout the year. It is one of the more adaptable Restrepia species for cool indoor cultivation.

Watch for — Root rot in over-wet medium: Fine Restrepia roots are especially susceptible to rot if the medium stays saturated. Use small pots with multiple drainage holes and a very free-draining mix; never use heavy potting soil.
