Cynorkis gibbosa is a tuberous terrestrial or rock-dwelling orchid from Madagascar, grown occasionally for its coral-pink flower spikes. Key to success is bright warmth, well-drained substrate with good airflow, and no watering after flowering as it dies back.

About
Cynorkis gibbosa is a species of orchid endemic to Madagascar. It may grow as a lithophyte or as a terrestrial plant, and is sometimes cultivated as an ornamental plant.
How to grow it
Cynorkis gibbosa is somewhat uncommon in orchid collections. Plants in cultivation tend to appear different from their wild counterparts, with paler flowers and leaves often losing their darker spots.
In cultivation, this species appreciates bright and warm conditions, no lower than 20 °C (68 °F) in winter and no higher than 35 °C (95 °F) in summer. To prevent rot, plants should be provided with well-drained substrate and kept in a ventilated area with ample air flow. Substrate should be replaced every two or three years, just before active growth begins. The plant should not be watered directly after it finishes flowering and begins to die back.
Where it grows
Wild Cynorkis gibbosa can be found in the regions of Madagascar formerly known as Antananarivo Province, Antsiranana Province, Fianarantsoa Province, Toamasina Province, and Toliara Province. It inhabits the edges of humid, subhumid, and montane forests at elevations of 500–2,499 m (1,640–8,199 ft) above sea level, as a lithophyte growing on damp rocks or as a terrestrial plant growing in peaty or humus-rich soil. It can be found in shaded positions or in more open (but still sheltered) places such as rocky outcrops, cliffs, and roadsides.
