The healing garden is a new landscape type emerging in recent years, which takes rehabilitation and health function as the design theme of landscape. The horticultural therapy of healing gardens has achieved good results in the rehabilitation of chronic disease, thinking dysfunction, etc, as shown by practices. In order to use the plant landscape effect of healing gardens more effectively, we need to establish a compound plant perception system based on five sense of vision, hearing, smell, taste, and touch. Multiple plants gardening system with the themes for children and the elderly were designed for different service groups. The plant space experience systems, merged as a suitable combination of different spatial scales, were created with the core of rehabilitation people. Optimizations in three aspects of the plant use were adopted in the rehabilitation landscape. Combinations of the plant’s color, smell, shape together with the construction of landscape’s whole environment were adopted to satisfy the physiological and psychological needs of different vulnerable groups including the old, young, sick, disabled and so on.
