The Aquatic Garden of XTBG is a wonderful tourist attraction. Giant water lilies are the the most attractive plants, including Victoria amazonica, Victoria cruziana, and Victoria 'Longwood Hybrid' .

One seedling of Victoria 'Longwood Hybrid' was sent to XTBG as a gift by Nanjing Botanical Garden Mem.Sun Yat-Sen in April 2009. After a year of careful cultivation, tens of Victoria 'Longwood Hybrid' are now in bloom in the Aquatic Garden, vying for attraction with other water lilies.
