What is the difference between Japanese euonymus (Euonymus japonicus) and Jiaodong euonymus (Euonymus kiautschovicus)?

Japanese euonymus and Jiaodong euonymus are evergreen plants of the same genus but different species, both good materials for hedges. The leaves of both are leathery, and there is no obvious difference in leaf shape, so many people lump them together. The main differences between the two are described below: 1. Plant form. Japanese euonymus has a compact form, the branches are relatively upright, and the natural branching point of the side branches is relatively high; Jiaodong euonymus has a loose form, the natural branching point of the side branches is relatively low, and the branches at the base are prostrate and can take root. 2. Leaves. Although the leaves of both are leathery, the fine serrations on the leaf margin of Japanese euonymus are more obvious, and they feel clearly prickly to the touch; the serrations on the leaf margin of Jiaodong euonymus are not very obvious, and the prickly feel to the touch is not obvious. 3. Fruit. The fruit of Japanese euonymus is nearly spherical and pale pink; the fruit of Jiaodong euonymus is oblate and pink.
