Dendrobium speciosum, commonly known as the Rock Orchid or Cane Orchid, is an epiphytic or lithophytic perennial herb native to a variety of habitats along the eastern coast of Australia, from Queensland to Victoria. It thrives in diverse environments, including coastal and subalpine areas, rainforests, and open forests, often forming extensive colonies on rocks, cliff faces, and trees. This orchid can be found at elevations from sea level up to 2953 feet (900 meters). Dendrobium speciosum is notable for its large, cylindrical pseudobulbs and leathery leaves, which can reach lengths of up to 24 inches (60 centimeters). It produces showy racemes of cream to yellow flowers, which can be quite spectacular when in full bloom, typically in late winter to spring.

The Rock Orchid is valued for its impressive floral displays and its ability to attract pollinators such as the stingless bee Tetragonula carbonaria. It is a popular choice for cultivation in orchid collections and is often used in mounted displays due to its epiphytic nature. Gardeners appreciate its adaptability to a range of light conditions, from bright indirect light to dappled shade, and its preference for well-draining orchid potting mixes. While it is relatively easy to maintain, it does require high humidity and regular watering during the growing season, with a reduction in water during the dormant period. Overwatering or poor drainage can lead to root rot. It is also susceptible to pests such as scale insects and aphids.CC BY-SA 4.0
