Color-leafed trees are mostly deciduous trees. Make use of the color changes of colorful tree species to create a colorful and refreshing feeling. Colored-leaf tree species, with green flowers in spring, tree-lined in summer, colored leaves in autumn and no shading in winter, give visitors the impression of four distinct seasons and enhance the sightseeing of urban gardens. Therefore, color-leafed tree species can be used in humanized plant landscaping design, and color-leafed tree species are an important part of landscaping. Color-leafed plants are mainly used for landscaping. In flower beds, flower borders, flower ponds, lawns, courtyards, parks and scenic spots, gorgeous colors can be created, mainly including solitary planting, opposite planting, cluster planting, group planting and sticking planting. Single planting can play a central role in the landscape or guide the line of sight, and cluster planting can enrich the landscape color and activate the garden atmosphere. Different time, environment, plant species and their ecological conditions should be comprehensively considered in color-leafed plant landscaping, so that rich plant colors appear alternately with the change of seasons, and the plant landscape of each division of garden green space can be highlighted in one season. The color, fragrance, individual, leaf and flower form of the landscape combination of flowering shrubs are various, so we should distinguish the primary and secondary functions and highlight the key points.
