Abstract: The species and the distribution of wild Hedychium ornamental resources in China were systematically investigated by the wild work and extensive review of literature and specimens. 26 species，2 varieties，1 form of wild Hedychium were introduced into Guangzhou in open ground and green house separately. The results showed that：There are 32 species，2 varieties，1 form of wild Hedychium plants in China including 2 new species，1 new form and 2 new-recorded species；Some species have specific breeding potential in view of the color of flowers，the type of fragrance and the height of plant in this genus；10 species have wide distribution volumes，but some species with high ornamental values are endangered；17 taxa were successfully introduced into Guangzhou；High temperature in summer is the most important factor to restrict the introduction of Hedychium to Guangzhou. Additionally，some reasonable advices are given on how to exploit the ornamental resources of wild Hedychium plants in China.
