Ceratostema gualaquizensis Culture:

• Light: Prefers bright, filtered light (similar to dappled forest sunlight); avoid harsh midday sun to prevent leaf scorch but ensure sufficient light for flowering. 
• Temperature: Thrives in cool to intermediate conditions (18–24°C / 64–75°F daytime, 10–15°C / 50–59°F nighttime), benefiting from a slight nocturnal drop to mimic its high-altitude cloud forest origins. 
• Humidity: Requires high humidity (70–80%), achievable via humidifiers, pebble trays, or enclosed environments like terrariums. 
• Watering: Keep the substrate consistently moist but never waterlogged, reducing slightly in cooler months; use rainwater or distilled water if tap water is hard. 

Additional Notes: 

•  Mimicking its natural cool, humid, and airy habitat is key to success!
