Bulbophyllum graveolens

Introducing the exotic and captivating Bulbophyllum graveolens, a rare orchid native to the lush rainforests of New Guinea. Discovered in the Central Province of Papua New Guinea, this magnificent orchid thrives in the dappled sunlight of the forest canopy, making it an enchanting addition to any orchid enthusiast's collection.

Bulbophyllum graveolens is characterized by its striking features, including a single large leaf and numerous long white roots cascading from a creeping rhizome. Its elegant, erect to arching inflorescence boasts delicate, waxy flowers with intriguing details. The pseudobulbs, measuring 6-10 cm long and 2.5-4 cm in diameter, exhibit a deeply grooved texture, adding to the plant's allure.

In the fall, Bulbophyllum graveolens produces an apical umbel of 8 to 9 long-lasting flowers, each adorned with yellow-green petals and sepals featuring darker veins and red dots at the base. The lip, small and dark scarlet, adds a dramatic contrast to the ensemble. While its fragrance may be considered unpleasant to some, its unique appearance and rarity make it a prized possession for orchid aficionados.

Cultivating Bulbophyllum graveolens requires attention to specific environmental conditions to ensure optimal growth and flowering. Providing filtered or dispersed light with a level of 12000-23000 lux is essential, while avoiding direct sunlight exposure during midday. Adequate air movement is also crucial for maintaining healthy plants.

Temperature control is paramount, with daytime temperatures ideally ranging from 27-31°C and nighttime temperatures around 22-23°C, ensuring a daily fluctuation of 5-8°C. Additionally, maintaining humidity levels between 70-75% throughout most of the year, increasing to 75-80% in winter, promotes vigorous growth and blooming.

When it comes to substrate and growing media, Bulbophyllum graveolens thrives in a loose, fast-draining medium that retains moisture without causing root rot. Growing it attached to pieces of tree fern or cork, or in baskets with well-draining substrate, ensures the delicate root system remains healthy.

During the active growth period, regular watering is essential, ensuring the substrate remains slightly moist but not waterlogged. Fertilization with a balanced orchid fertilizer at 1/4-1/2 strength weekly supports healthy growth and flowering. Adjusting the fertilizer composition to favor nitrogen during spring and summer, and phosphorus in late summer and autumn, optimizes nutrient uptake.

In winter, Bulbophyllum graveolens enters a rest period, requiring reduced watering and fertilizer until new growth appears in spring. Maintaining a dry period while providing sufficient humidity through morning fogging and occasional watering allows the plant to rejuvenate and prepare for the next growing season.
