Rhododendron dalhousiae, also known as Lady Dalhousie's rhododendron, is a species of rhododendron first identified in the Eastern Himalayas by Joseph Dalton Hooker during his 1848-1850 expeditions to what is now Sikkim. It is an epiphyte, normally found on tree, cliffs, and boulders, in the lower parts of the Himalayas at altitudes between 5,000 and 9,000 feet. Since its first identification by Hooker, it has been found throughout the southern border of Tibet, Bhutan, Nepal, and northeastern India, particularly in Arunachal Pradesh.
At the 2010 International Conference of Rhododendrons: Conservation and Sustainable Use, Hemant K. Badola suggested that Himalayan rhododendrons can act as a bellwether for climate change, particularly species with large and ostentatious blooms such as R. dalhousiae. Plant phenology, the discipline of the timing of recurring biological events, is significantly affected by seasonal environmental factors such as temperature and precipitation levels. R. dalhousiae, as weather-sensitive species, is an indicator species of a healthy forest, and may also be a candidate for phenological monitoring of global climate change.
There are reports that the leave extract of R. dalhousiae var. rhabdotum is used as an insect repellent by the Monpa people in Arunachal Pradesh. Other sources suggest that an aqueous stem extract can be used for headache relief.
