Paphiopedilum glaucophyllum

Paphiopedilum glaucophyllum is a distinctive multifloral Paphiopedilum native to East Java, Indonesia, where it grows in wet tropical habitats at approximately 200–700 m elevation. It is a terrestrial to lithophytic orchid with attractive glaucous blue-green leaves and a long, branching inflorescence capable of producing many flowers successively.

The flowers are approximately 8–8.5 cm across. The dorsal sepal is white to cream with a yellow-green center and maroon veining, while the elongated petals are white with purple spotting and often twist toward the tips. The pouch is pink to purple with darker purple spotting and pale yellow margins. A mature inflorescence can produce 20 or more flowers successively, although usually no more than two flowers are open at one time, allowing the plant to remain in flower for an extended period.

Care Tips:

• Light: Provide bright, filtered light or light shade. Paphiopedilums generally perform well under about 1,000–2,000 foot-candles. Avoid harsh midday sunlight.
• Watering: Keep the growing medium consistently lightly moist, but never saturated. P. glaucophyllum should not be allowed to remain completely dry for extended periods.
• Growing Medium: Use a moisture-retentive but well-aerated Paphiopedilum mix, such as fine or medium bark, perlite, and suitable organic material. Good drainage is essential.
• Humidity: Moderate to high humidity is beneficial, with good airflow. Avoid stagnant conditions when the foliage and medium are wet.
• Temperature: This is a warm-growing, multifloral Paphiopedilum. A general range of approximately 21–29°C (70–85°F) during the day with slightly cooler nights is suitable. AOS specifically notes that multifloral and mottled-leaf Paphiopedilums prefer warmer conditions.
• Fertilizing: Feed regularly with a diluted balanced orchid fertilizer during active growth. Flush the medium periodically with clean water to prevent fertilizer-salt buildup.
• Airflow: Provide gentle, continuous air movement, particularly in warm and humid conditions.
• Potting: Use a relatively small pot with excellent drainage. Repot when the medium begins to break down, generally every 1–2 years.
• Flowering: Avoid cutting the inflorescence after a single flower fades. This species produces flowers successively from the same inflorescence, so the spike can continue flowering for an extended period.
