Controlling the flowering of ornamental plants for production is important. The mechanism of the regulation of flowering in higher plants has been elucidated recently and has revealed ways to regulate flowering of ornamental plants. This paper briefly summarizes how to regulate flowering of ornamental plants and preliminary technical analysis to improve the flowering of these plants. Based on the analysis of the regulation of flowering in higher plants, the study of the flowering mechanism in ornamental plants has made substantial progress, as has transgenic research of ornamental plants. The use of molecular tools to design breeding and change the flowering stage of ornamental plants will break through the limitations of traditional methods; the prospects of research and application are very broad.
