Bulbophyllum depressum is a compact epiphytic orchid known for its intriguing and small, fleshy leaves. It produces unique, small flowers that emerge on slender stems, often with a subtle but intricate appearance. Like many orchids, it prefers humid environments and grows well in containers or mounted on bark, making it a good option for indoor cultivation where these conditions can be met. The plant has a creeping growth habit, with pseudobulbs forming along a rhizome, each producing one or two leaves.

Native to
Bulbophyllum depressum is native to the tropical regions of Southeast Asia, particularly in countries like Thailand and Vietnam. In its natural habitat, it is found growing on trees in humid, shaded forests, where it benefits from high humidity and filtered sunlight.

Water
As an epiphyte, Bulbophyllum depressum requires regular watering, but the medium should dry out slightly between waterings. It benefits from a well-draining potting mix, such as one designed for orchids, or can be mounted on bark or a wooden plaque, where it can be misted regularly.

Light
This orchid thrives in bright, indirect light, similar to what it would experience under the forest canopy. Direct sunlight should be avoided as it can cause leaf burn. Low to moderate light levels can work, but brighter, filtered light will encourage better growth and blooming.

Humidity
High humidity, ideally between 60% and 80%, is necessary for Bulbophyllum depressum. It is also well-suited to growing in terrariums, where the humidity can be kept at optimal levels.

Temperature
The ideal temperature range for this orchid is between 18°C and 24°C. It prefers a stable environment without drastic temperature changes. Avoid exposing the plant to temperatures below 15°C, as cold drafts can stress the plant and hinder its growth.
