It has been demonstrated that the plant's color, smell in gardens as well as horticultural activities in the space created by plants play a significant positive role in the non-medical rehabilitation. Therefore, the healing garden designed for horticultural therapy has become the hot spot of modern landscape design. A number of studies have been carried out in this aspect both in China and abroad. This paper will compare different types of domestic and foreign cases of healing landscape. Corresponding analysis, summary, and revelations are obtained. Investigations on how to achieve the ideal effect of rehabilitation through the construction of plant landscape will also be carried out. These results can be used as references for the domestic healing garden practice, which is still in the developing stage.
