Jasmine, a long-time favorite flower of the Chinese, loved for its scent and use in tea, has been banned by the Chinese government. Starting in February, there was talk of a "jasmine revolution" floating around the internet and the Chinese government put in place an open-ended ban on selling jasmine at the retail and wholesale markets in Beijing. Even famous poetry about the fragrant flower has been yanked off the internet.

Interestingly, as the rural growers of jasmine in China are now struggling with a severe drop in value of their jasmine plants, jasmine remains the most expensive floral scent to produce.
