In the Ili River Valley and the oasis towns around Kashgar, Xinjiang, farmers begin harvesting roses before dawn each May and June, plucking petals from damask roses at the precise moment when aromatic compounds are most concentrated. This centuries-old tradition, rooted in the Silk Road exchange of plants and knowledge, produces some of the world’s most prized rose oil — a commodity that can fetch more than $10,000 per kilogram.
Xinjiang’s rose-growing regions cover an estimated 20,000 to 40,000 hectares, making this northwestern Chinese autonomous region one of the world’s largest concentrations of cultivated roses, comparable to Bulgaria’s Rose Valley, Turkey’s Isparta province, and Morocco’s Dadès Valley. The industry thrives because of a unique combination of geography, climate, and human skill.
Geography and Climate
The Ili Valley sits between the Tianshan mountain ranges at elevations of 500 to 1,500 meters, receiving 300 to 600 millimeters of annual precipitation — exceptional for Central Asia’s arid interior. Near Kashgar, the Tarim Basin’s alluvial fans provide alkaline, mineral-rich irrigation water from glacial melt. Winters bring temperatures below minus 20 degrees Celsius in the north, satisfying the rose’s chilling requirement, while summer days can exceed 35 degrees Celsius, with sharp diurnal swings that concentrate aromatic compounds.
The Rose and Its Harvest
The dominant species is Rosa damascena, the damask rose, with 25 to 35 petals per flower in pale pink. Local varieties include the Ili rose and Kashgar damask, each with subtle differences in oil profile. Harvesters work from about 3 a.m. to mid-morning, before heat causes volatile compounds to evaporate. An experienced picker gathers 15 to 25 kilograms of petals per hour.
Steam distillation of three to five metric tons of petals yields just one kilogram of pure rose absolute. The oil contains geraniol, citronellol, and linalool — compounds confirmed by gas chromatography to meet premium quality standards. Rose water, a byproduct, is used in cooking, cosmetics, and traditional medicine.
Historical and Economic Context
Roses likely arrived in Xinjiang via Persian horticultural traditions carried along the Silk Road from the seventh century onward. By the Tang Dynasty (618–907 AD), Chinese sources mention imported roses and rosewater. Today, the industry faces global competition but benefits from growing Chinese domestic demand for luxury cosmetics and natural food products.
Challenges and Future
Climate change is shifting bloom dates earlier and threatening water supplies as glaciers retreat. The traditional karez underground irrigation systems, some more than 2,000 years old, are falling into disrepair. Small family farms, which maintain quality through generations of experience, face pressure from labor migration and consolidation.
However, geographic indication protection for “Ili rose” or “Kashgar rose” products, along with investments in climate-adaptive research and contract farming models, offer pathways for resilience. The deep cultural integration of the rose — in Uyghur cuisine, poetry, and festivals — ensures that cultivation will persist as long as communities continue to value the flower beyond its market price.
