With the rapid development of urban construction and urban and rural garden greening, people's requirements for environmental quality are getting higher and higher. Whether in residential areas, public green spaces, or by lakes and riversides, on the basis of ordinary greening, it is necessary to go beyond simply planting flowers and grass. While greening, beautifying, and adding fragrance, we must further implement the colorization of greenery environments. Therefore, with the widespread application of colorizing plants, the types and quantities of colored-leaf plants are far from meeting the current demands of urban and rural landscaping.
