1. Identification and Origin
 
 
Genus: Gongora (Orchidaceae, subtribe Stanhopeinae).
 
 
Origin: Hybrid derived from Gongora irmgardiae and Gongora seideliana, two species native to the tropical rainforests of Central and South America (Mexico, Colombia, Ecuador).
 
 
Natural habitat: Epiphytic orchids, growing on trunks or branches in shaded, humid, and well-ventilated areas.

2. Appearance
 
 
Stems: Pendant, bearing spaced-out pseudobulbs.
 
 
Leaves: Elongated, leathery, light to medium green in color.
 
 
Flowers: In hanging clusters, often fragrant, with bright colors (yellow streaked with reddish-brown, inherited from G. seideliana).
 
 
Blooming period: Mainly in autumn or winter, depending on cultivation conditions.

3. Cultivation Conditions (for 15 in vitro plants)
Temperature
 
 
Day: 20–28°C.
 
 
Night: 16–18°C minimum (never drop below 15°C).
 
 
Day/night drop: A differential of 5–8°C is ideal to promote blooming.

Humidity
 
 
Ideal rate: 60–80%. Maintain high ambient humidity, especially during the active growth phase.

Light
 
 
Intensity: Filtered light, without direct sun (ideally near an east or west window, or under greenhouse shading).
 
 
To avoid: Direct exposure to the sun, particularly in summer (risk of leaf burns).

Substrate
 
 
Recommended: Pure sphagnum moss or a mix of fine bark (60%) and sphagnum moss (40%) to ensure good drainage and moisture retention.
 
 
Repotting: To be done every 1 to 2 years, preferably in spring, in a well-draining pot or basket of an appropriate size (rather small).

Watering
 
 
During growth: Regular watering every 2–3 days, letting the substrate dry slightly between waterings.
 
 
During rest: Reduce the frequency, but prevent the substrate from drying out completely.
