Care notes
CultivationThis tropical, highland orchid species requires specific growing conditions to grow well. Plants are best grown in pot with fresh sphagnum moss, or mounted if sufficient humidity can be provided. Moss should be replaced regularly - every, or every other spring when the new growth starts. Humidity of over 80% and excellent air movement are essential. To grow well, plant requires a temperature of 10-15°C between day and night. This species has exceptionally long-lasting flowers that can last up to one year if grown in optimal environment. See indoor orchid cultivation
