National Tree of Bhutan: The Himalayan Cypress

The Himalayan cypress (Cupressus torulosa), called Tsenden in Dzongkha and sometimes referred to as the Bhutan cypress, is the national tree of Bhutan. An evergreen conifer of the family Cupressaceae, it grows at elevations between 1,800 and 3,500 metres across Bhutan and parts of the western Himalayas, reaching heights of up to 45 metres with trunk diameters of approximately 90 centimetres. The tree's grey-brown bark peels in longitudinal strips; its crown is broadly conical in young specimens and more spreading in mature trees. Few plants are as deeply embedded in Bhutanese spiritual, literary, and material culture as the cypress — Bhutan's poetic name Tsenden Köpéjong ("the country bestrewn with cypress") opens the national anthem.

Religious and Spiritual Significance

The Himalayan cypress has been planted near temples, monasteries, and dzongs throughout Bhutan for centuries. In Bhutanese Buddhist tradition, the tree's straight, upright form and evergreen nature are associated with spiritual endurance and the aspiration toward enlightenment. Planting a cypress beside a new lhakhang (temple) is a customary act of consecration, and mature cypresses near religious buildings are regarded as guardians of sacred space. Some of the oldest specimens in the country stand at pilgrimage sites, their antiquity interpreted as evidence of the site's sanctity.

Among the most celebrated is the large cypress beside Kurjé temple in Bumthang, said by tradition to have grown from the walking staff of Guru Rinpoche (Padmasambhava), who visited Bhutan in the eighth century CE. Whether historical or legendary, such stories reflect the depth with which Bhutanese culture has woven the cypress into its religious narrative. The cypress also features in sang purification rituals: its branches are among the preferred aromatics burned in fire-offering ceremonies that punctuate the Bhutanese religious calendar, the smoke understood to carry prayers and purify the surroundings.

Material Uses

Tsenden timber is among the most prized building materials in Bhutan. Its aromatic, dense, and rot-resistant heartwood has been used for centuries in the construction and renovation of dzongs, monasteries, and temples. The scent of cypress pervades older buildings, contributing to the atmosphere that visitors to historic structures invariably note. Cypress timber was extensively used in reconstructing Wangduephodrang Dzong after the fire of 2012, a project that placed unusual pressure on existing wild populations.

Cypress wood is also the standard material for funeral pyres in Buddhist cremation practice. Its aromatic properties, high heat output, and religious associations make it the preferred choice. The same aromatic oils that give the wood its scent are extracted for incense production — cypress incense sticks and powder are manufactured in several Bhutanese dzongkhags and sold at monasteries and markets. Traditional medicine incorporates cypress resin and essential oil in preparations for inflammatory conditions.

Conservation

Wild populations of Cupressus torulosa occur naturally only in Bhutan and adjacent parts of the western Himalayas, making Bhutan's populations globally significant. The Dangchu valley in western Bhutan contains the largest known remaining stands. Demand for cypress timber — driven both by religious construction projects and general building use — has placed sustained pressure on wild populations. Illegal logging compounded legal extraction particularly in the period following the Wangduephodrang Dzong fire.

Between 2016 and 2018, Botanic Gardens Conservation International (BGCI), working alongside the Royal Botanic Garden Serbithang, Royal Botanic Garden Edinburgh, Bhutan's Forestry Department, and local Dangchu communities, planted approximately 41,000 seedlings across more than 12 hectares in the Dangchu valley. Seed material was collected from multiple mother trees to maximise genetic diversity. Project managers noted that cypress trees require approximately 70 years to reach harvestable maturity, framing the restoration work explicitly as an investment for future generations.

Symbolism

In Bhutanese culture, the cypress's capacity to grow in harsh, rocky terrain while maintaining a strong, upright form is understood as a model of the Bhutanese character — simplicity, hardiness, and resilience in adversity. This symbolism is not recent: the tree appears in classical Dzongkha literature, in dzong murals, and in traditional textile motifs long before its formal designation as the national tree. Its evergreen nature links it to ideas of permanence and the continuity of both the Dharma and the Bhutanese state.
