Cedrus deodara, commonly known as Himalayan Cedar, the Deodar Cedar or just Deodar, is native to the western Himalayas region. It naturally occurs at altitudes of 1500 – 3200m. This tree is the national tree of Pakistan. It was brought into the UK from the Himalayas in 1831, where it became a favored tree to plant on the lawns of large country houses and Georgian rectories.

The etymological root of the binomial name Cedrus is derived from the ancient Greek kedros which was used to describe many plants of the Cedrus and Juniperus genera. Deodara is derived from the Sanskrit devadāru ‘wood of the gods’.

The landscape architect may find Cedrus deodara useful as large, evergreen specimen parkland tree. Once established this tree is drought tolerant.
