A major international horticultural exposition opens in Qingdao, east China's Shandong Province, on April 25.

The expo will last for 184 days with the theme From the Earth, For the Earth, and it marks the fourth time a Chinese mainland city has hosted a horticultural event of this scale after Xi'an in Shaanxi Province, Kunming in Yunnan Province and Shenyang in Liaoning Province.

A wide variety of gardening styles are on display. Plants cultivated from seeds carried back by China's first manned deep-sea submersible Jiaolong are also on display.
