Name: Dendrobium leucocyanum

Description & Notes: A rarely cultivated Dendrobium species from the highlands of New Guinea. It remains relatively compact and is particularly interesting due to its unusual flower coloration and alpine character. As a highland species, it prefers cool to temperate conditions, high humidity, and continuous air movement; consistently warm nights are unfavorable.

Light: Bright with filtered, indirect light. Good lighting is important, but avoid intense direct midday sun.

Temperature: Cool to temperate, ideally around 15–22 °C during the day and 8–15 °C at night. Especially during warm periods, the coolest possible nights and very good air movement are beneficial.

Water & Humidity: Keep evenly slightly moist and use soft, low-mineral water whenever possible. The roots should not dry out completely, but at the same time, waterlogging must be avoided. High humidity of about 70–90% is favorable, always combined with good air movement.

Substrate: Fine, very airy orchid substrate made of bark with some sphagnum, or mounted culture if humidity is sufficiently high. The root environment should remain moist but always well-ventilated.
