China's two national botanical gardens, one south and one north, have been officially put into operation. The North Park of the National Botanical Garden will also build a national plant germplasm resource bank.
There are about 3,8 species of higher plants in China, accounting for 1/10 of the world, which can be called the world's plant treasure house. In July 2022, three troll taro plants achieved the first group flowering in the artificial cultivation state, and produced fruits and seeds through artificial pollination.
