Bulbophyllum

Bulbophyllum is a large and diverse genus of orchids, belonging to the subfamily Epidendroideae. It is one of the largest genera of flowering plants, with estimates of over 2,000 species. These orchids are found throughout tropical and subtropical regions worldwide, with the greatest diversity concentrated in Southeast Asia and the Pacific islands.

The genus is characterized by its pseudobulbs, which are modified stems that store water and nutrients. The size and shape of these pseudobulbs vary greatly among species. Bulbophyllum orchids typically have a single, terminal leaf per pseudobulb, though some species may have more. The inflorescences are usually racemose or paniculate, bearing numerous small flowers. The flowers themselves exhibit a wide range of colors, shapes, and sizes, often with elaborate structures and sometimes emitting strong odors, which can be attractive to specific pollinators like flies.

Cultivation of Bulbophyllum orchids can be challenging due to their diverse habitat requirements. Many species prefer high humidity, good air circulation, and intermediate to warm temperatures. They are often grown in well-draining orchid mixes, such as bark or sphagnum moss, and require consistent watering without allowing them to become waterlogged. Their adaptability and varied horticultural appeal have made them a popular subject among orchid enthusiasts, though their sheer number and specific needs present a significant undertaking for collectors.
