Guarianthe aurantiaca 'Sin Manchas'

This is a compact and resilient epiphytic orchid from Central America, prized for its clustered, vibrant flowers. The 'sin manchas' (without spots) variety is celebrated for its solid, unblemished orange or yellow-orange color.

• Light: Bright, indirect light. Provide high luminosity, but shield from direct midday sun. Recommended light is 25000-35000 Lux.
• Temperature: Intermediate to warm. Day: 70-85°F (21-29°C). Night: 55-65°F (13-18°C). A distinct day/night temperature drop is crucial for successful flowering.
• Humidity: High (70-85%). Pair high humidity with excellent air circulation to prevent fungal issues.
• Watering: Water liberally during the spring/summer growth period, allowing the substrate to dry out quickly between waterings. Use a very coarse, fast-draining potting mix. Reduce watering significantly during the winter rest period.

Additional Notes

This medium-sized plant, which can reach up to 12 inches in height, produces clusters of 4 to 11 small (2.5-4 cm) solid orange or yellow-orange flowers. The flowers are typically unscented.
