Bulbophyllum carunculatum x Bulbophyllum paluense

This exceptional hybrid combines the striking beauty and distinct characteristics of Bulbophyllum carunculatum and Bulbophyllum paluense, resulting in a fascinating orchid that captivates with its vibrant colors and unique floral structure.

Bulbophyllum carunculatum: Native to Sulawesi, Indonesia, Bulbophyllum carunculatum thrives in primary and remnant forests at elevations of 800 to 900 meters. This medium-sized, warm-growing epiphyte can reach up to 45 cm in height. It features ovoid pseudobulbs, about 6 cm long, each supporting a single, elliptic to obtuse leaf up to 36 cm long and 7 cm wide. The leaves are distinctly petiolate, adding to the plant's elegant form. Blooming in the summer, this species produces a 45 cm long inflorescence with up to 12 successively flowering fragrant blooms. The flowers are a striking golden-yellow with a dark purple lip, which often appears almost black. The petals and sepals have a distinctive shape, with the lip being fleshy and papillary.

Bulbophyllum paluense: Also native to Sulawesi, Bulbophyllum paluense is found in similar forested habitats, often growing at slightly higher elevations. This species is characterized by its compact growth habit and smaller pseudobulbs compared to Bulbophyllum carunculatum. The leaves are also smaller but share the same elliptic to oblong shape. The flowers of Bulbophyllum paluense are noted for their unique shape and coloration, typically featuring a mix of green and purple hues with a fringed, almost feather-like lip. Bulbophyllum paluense has similar cultural requirements to Bulbophyllum carunculatum, thriving in warm temperatures and high humidity. It prefers moderate light levels and requires consistent moisture in its growing medium.

Cultivation Tips:

Light: Provide dappled shade or partial shade, with light levels around 18,000-30,000 lux. Avoid direct sunlight, which can scorch the leaves.

Temperature: This hybrid thrives in warm conditions, with ideal temperatures ranging from 21-27°C. Ensure a temperature drop of 6-8°C at night to encourage blooming. Protect from frost and extreme heat.

Humidity: Maintain high humidity levels of around 80% year-round. Good air circulation is essential to prevent fungal issues in such humid conditions.

Watering: Water abundantly during active growth, allowing the medium to dry slightly between waterings. In winter, reduce watering but do not let the plant dry out completely. Soaking the plant during watering and ensuring the medium drains well will help maintain moisture without causing rot.

Fertilization: During the growing season, fertilize weekly with a diluted orchid fertilizer. Switch to a phosphorus-rich fertilizer in late summer to encourage blooming.

Repotting: This hybrid should be repotted when new roots begin to grow or when the medium breaks down. Use a well-draining mix of pine bark or tree fern fibers, with added perlite or peat moss for moisture retention. Handle the roots with care to avoid transplant shock.
