Dendrobium pulchellum var. alba
The rare alba form of the delightful Dendrobium pulchellum, this stunning orchid is a must-have for any collector. Widely distributed across India and Southeast Asia, including regions like Nepal, Thailand, Vietnam, and Myanmar.

This species thrives in altitudes of 1500-2200 m. It is a medium to large epiphytic orchid, with long, slender, erect stems that reach up to 220 cm in height, adorned with purplish sheaths and linear-oblong leaves. This deciduous orchid produces striking, long-lasting flowers that bloom from late winter to spring. Each drooping inflorescence carries 5 to 15 fragrant flowers, with a diameter of 8-13 cm. The flowers feature a creamy white lip with scarlet spots, and petals that vary from white to yellow, sometimes with pink or apricot accents.

Cultivation Tips:

• Light: Dendrobium pulchellum var. alba thrives under 30,000-45,000 lux light levels. While partial shading is needed during the warmer months, ensure the plant receives as much light as possible without burning the leaves.

• Temperature: This orchid grows in a wide temperature range, from warm to cool climates. It enjoys summer daytime temperatures of 27-28°C, with nights around 20°C. Winter temperatures should be cooler, with days at 26-30°C and nights between 10-12°C. Ensure a daily temperature variation of 7-19°C for optimal growth.

• Humidity: Humidity should remain high during the summer months, around 80-85%. In winter, it can drop to about 55%, particularly during its resting period.

• Mounting and Potting: Ideal for mounting on cork or tree fern, Dendrobium pulchellum var. alba benefits from high humidity and frequent summer watering when mounted. Alternatively, you can use hanging pots or baskets with a loose, quick-drying medium. Repotting should be done when new roots appear, but be sure to leave old shoots intact, as they can flower for up to three years.

• Watering: During the growing season (spring to early autumn), water abundantly, keeping the medium consistently moist. As growth slows in autumn, reduce watering gradually.

• Fertilizing: Apply a balanced orchid fertilizer at 1/4-1/2 strength weekly. From spring to mid-summer, use a high-nitrogen formula, switching to a high-phosphorus fertilizer from mid-summer through autumn to promote strong blooming.

• Rest Period: A dry, cool rest period in winter is essential for initiating blooms. Reduce watering to allow the plant to dry between waterings, but avoid keeping it dry for extended periods. Light misting is enough during the resting phase, which should last 3-6 weeks.

Dendrobium pulchellum var. alba is a captivating and rewarding orchid for experienced growers, offering fragrant blooms and a striking display when given the right care. Highly recommended for those seeking a rare and beautiful addition to their collection!
