Abstract: Populus deltoides‘Zhonghong' (Chinese Red Foliar Poplar) is a new poplar variety which was cultured through multiple years' selection. It originated from a bud mutation of the poplar variety 2025. The male tree of ‘Zhonghong' grew fast,and the variety would be a good ornament tree because its foliar color varied in different season. The foliar and twig appeared purplish red color from sprout period to early summer,and the new leaf and twig exhibited vivid violet-red from early summer to mid-autumn with the mature leaf in the mid-lower crown green,and then the leaves became apricot-red gradually after mid-autumn until defoliation. The variety was adaptable to grow in many regions of China.
