Abstract: The paper aims to enrich the variety of colored-leaf trees in Beijing and expand the planting area of Populus euramericana cv‘. Hongxia’。The Populus euramericana cv‘. Hongxia’was introduced to Fangshan, Beijing from Chengdu, Sichuan, the phenological period observation, color change observation, cutting propagation, grafting propagation and the adaptability analysis of the plant to soil and light intensity were carried out. The results showed that: Populus euramericana cv.‘Hongxia’could complete the life cycle in Fangshan, Beijing; the survival rate of cutting propagation was over 80%, and the survival rate of grafting propagation was over 85%; it could grow in the refuse soil, the pasture soil and the architecture soil, but it grew in an undesirable way; it grew well in the nursery soil; the leaves were sensible to the stress reaction of the light intensity, and the colors of the leaves were bright; and there was the phenomenon of leaf scald, the leaf color may become green again and the leaves grew weakly; but the leaves grew well in the 75% of shading, and there was no phenomenon of leaf scald. The leaves of the tree could have the colorful effect of three colors: red orange, golden yellow and yellow green. In landscaping, Populus euramericana cv‘.
