Abstract: Plants are important elements of agricultural production and ecological environment construction. Landscape plants have certain ornamental values, which can make the environment beautiful and enrich people’s life. Introduction and domestication of plants can make landscape plant resources of Beijing more various, and also promote culture exchanges on plant. Based on the analysis of plant resources in Beijing, plants planted during a long time in the history were studied through textual research. Most landscape plants in Beijing were investigated in order to know how and when they were planted in the gardens of Beijing in the long history, which could help to make decision on introduction and domestication of other appropriate plants in the future.
