In its natural environment, Dendrobium kingianum usually grows in or around rocks (as a lithophyte), across much of eastern Australia, covering many habitats and weather patterns. I suspect that this variety of natural growth conditions is why Dendrobium kingianum is reputedly easy to grow in culture.
