However, there have been giant numbers of selected varieties being grown from early times; for example numerous alternatives or cultivars of the China rose have been in cultivation in China in the first millennium AD. It is believed that roses had been grown in lots of the early civilisations of temperate latitudes from a minimum of 5000 years ago.
