Classification: Orchidaceae family, Epidendroideae subfamily, Stanhopeinae tribe. Characteristics of the parents Gongora leucochila Origin: Mexico, Panama (0–1,600 m). Appearance: Size: Small (20–30 cm), conical pseudobulbs (8 cm). Leaves: 2 leaves per pseudobulb, leathery. Flowers: White to pale green, lip spotted with purple, sweet and waxy fragrance (spring).

Culture: Temperature: Warm (20–30°C). Light: 20,000–30,000 lux (filtered). Humidity: 70–85%. Substrate: Hanging basket with coarse bark or mount.

Gongora escobariana Origin: Colombia. Appearance: Size: Medium (30–50 cm), conical pseudobulbs. Leaves: 2 leaves per pseudobulb, leathery. Flowers: Reddish-brown to purple, contrasting lip, light fragrance.

Culture: Temperature: Warm to intermediate (18–28°C). Light: 20,000–30,000 lux (filtered). Humidity: 70–85%.

Expected hybrid (Gongora leucochila × escobariana) Appearance: Size: Small to medium (25–40 cm), conical pseudobulbs. Leaves: 2 leaves per pseudobulb, leathery. Flowers: Color: White-green to reddish-brown, spotted or contrasting lip. Shape: Typical of Gongora ("shoe-shaped" lip). Fragrance: Sweet and waxy (inherited from G. leucochila).

Blooming: Spring–summer, in pendulous clusters. Duration: 1–2 weeks per flower (Gongora have an ephemeral blooming). Culture (for 15 in vitro plants) Temperature:

Day: 22–28°C. Night: 16–20°C (difference of 6–8°C). To avoid: <15°C or >32°C.

Humidity: 70–85% (essential).

Tip: Use a humidifier or a terrarium.

Light:

Intensity: 20,000–30,000 lux (filtered, no direct sun). Source: East/west window or horticultural LEDs.

Watering:

Growth: Every 2–3 days (let dry slightly). Rest: 1–2 times/week. Method: Misting or quick soaking (avoid stagnant water).

Substrate:

Hanging basket: Coarse bark (70%), perlite (20%), charcoal (10%). Mount: Cork plaque or fern, with a thin layer of sphagnum moss. Repotting: Every 2–3 years, in spring.

Fertilization:

Growth: Balanced fertilizer (20-20-20) diluted to ¼, every week. Rest: Every 2–3 weeks.

Tips for a successful culture Optimal blooming: Maintain high humidity and a temperature difference. Cultivate in a hanging basket for the pendulous inflorescences.

Common problems: Lack of flowers: Increase light or humidity. Rot: Substrate too wet → repot in a more draining mix.

Propagation: Division: Separate pseudobulbs (3–4 per division). Keikis: Rare, but possible on mature spikes.

Advantages of the hybrid Original flowers: Intermediate color and fragrance.
