Saudi's 'city of roses' offers fragrant reminder of desert's beauty

After decades of pruning thorny bushes and working arduous harvests, Khalaf Allah al-Talhi has perfected the art of capturing the fragrant aroma of the desert rose in a bottle. Known as "the city of roses", the hills of Taif produce around 300 million of the area's signature pink roses annually at its 800 flower farms. During harvest, workers on Al-Talhi's farm are able to pick tens of thousands of flowers daily. But after working more than 40 harvests, the greater frequency of erratic weather -- including searing summer heat, frigid winters and unexpected flooding -- has presented a potent threat to Taif's famed roses.
