This field experiment aimed to identify the optimal planting density for establishing a management plan for ground-cover plants under roadside trees. Liriope platyphylla and Hosta longipes both widely used for planting under trees were selected as the plant materials and planted under Prunus serrulata var. spontanea at different planting densities. Based on the distance between each plant, 4 planting densities were used: 11%, 25%, 49%, and 83% with three replications. To estimate plant growth, plant height, number of leaves and tillers, fresh and dry weight, and visual quality were investigated. Liriope platyphylla exhibited relatively better growth at the highest planting density of 83%. For Hosta longipes, however, the lower growth was positively correlated with high planting density. Therefore, the optimal planting density for Liriope platyphylla is 83% and for Hosta longipes is 11%.
