After the accumulation of the Tang Dynasty, Song people's understanding of garden plants was more specific and in-depth. Not only does every garden have a large number of plant records, but also many special spectra of garden plants appear. Some of them have high botanical value. Li's book Luoyang Famous Garden records a large number of plants planted in private gardens. This book records 19 gardens, many of which are even dominated by plants. For example, "Tianwangyuan" has no garden pavilion, only hundreds of thousands of peonies. There are many kinds of flowers and trees in Li Renfeng Garden. The gardener's grafting technique is very high, and he can "judge the red and judge the white" and "compete with nature". There are dozens of kinds of peach, plum, apricot, lotus and chrysanthemum in the park. There are more than 100 species of peony and peony. "There will be" purple orchid jasmine Qionghua camellia ". Li also commented: "There are thousands of flowers and trees in the garden. "There are a lot of peonies, peonies, bamboos and peaches and plums growing in Guiren Garden. In addition, Song Dao is famous for its pine trees. " "Congchun Garden" is dominated by trees such as tung, catalpa, juniper and cypress, and various flowers and trees and pine and cypress are planted around the stream. It can be seen from the book that Luoyang at that time not only gathered a large number of flowers and trees, but also had a high level of introduction, cultivation and grafting, so some southern plants such as jasmine and camellia could grow there.
