About

Bulbophyllum maxillare is a rapidly expanding orchid characterized by its creeping stems that thrive on the bark of larger, lower branches of trees. This species flourishes in warm to hot environments, favoring partial shade and high humidity typical of tropical lowland forests. It features elongated, green to yellowish pseudobulbs that serve as reservoirs for water and nutrients, each topped with a solitary, leathery leaf that is oval to lanceolate in shape. From spring through autumn, flower stems can reach up to 15 cm in length, each supporting a single blossom in shades of reddish-purple, yellow, and white.

About the genus

This genus encompasses a broad range of primarily epiphytic, sympodial tropical orchids. These plants form clusters of small pseudobulbs that function as reservoirs for water and nutrients. Typically, each pseudobulb supports a single leaf. There are more than 2,000 recognized species within this group.

Care notes

Cultivation
Grow in an open, well drained but moisture-retentive mix of medium orchid bark, sphagnum moss and perlite. Shallow, wide pots or baskets are best used to accommodate its spreading habit. Bright filtered light is best as direct sunlight through glass can scorch its leaves. Prefers a minimum night temperature of 15°C and a maximum of 30°C in the daytime. Nighttime temperatures should be 10°C lower than daytime temperatures for good growth and is beneficial to induce flowering. High humidity is required along with gentle air movement. Allow plants to freely drain when watering and avoid plants sitting in water as this can cause roots to rot. Plants may be intolerant of hard tap water, so irrigate with rainwater at room temperature. Orchid fertiliser can be applied regularly throughout the growing season, March to September. Reduce watering and feeding in winter months. See indoor orchid cultivation for further advice
Pruning
No pruning required. Remove spent flower stem at the base
Propagation
Propagation by seed is only possible in a controlled laboratory environment. Mature plants may be divided when the plant overgrows its container. Each division should have at least 3 older pseudobulbs with a sufficient amount of stored energy and water, to support new growth and reduce stress after repotting
Pest resistance
May be susceptible to mealybugs and scale insects
Disease resistance
Generally disease-free
