Tourism has become a booster of rural development under the background of urban and rural integration and rural revitalization. From tourists’ perspective, the environmental perception results of rural tourist destinations directly affect the quality of tourists’ experience, satisfaction, and sustainable development of tourist destinations, and plants are one of the essential elements of the environmental perception system. A system of plant landscape perception elements in rural tourism destinations is constructed based on UGC data, supplemented by ROST CM 6 and NVivo 11 in the research. Then improvement strategies for rural tourist destinations’ plant landscapes are proposed after IPA analysis. The study shows that the characteristics of the perception of plant landscapes in rural tourist destinations are as follows: (1) The network of the perception is centered aggregated and averagely diverged, and the positive emotions are apparent. (2) The diversification of perception dimensions is prominent. (3) The performance of perception elements varies greatly, and the satisfaction is overall high. Aesthetic features are still the focus, and cultural features are potential factors. Based on this, it is proposed that the plant landscape of rural tourist destinations in the future can be improved by fully utilizing native tree species to make characteristics of the landscape, sustaining the best time to view the plant, and promoting plant-derived culture could be participated and industrialized. Finally, the prospect of the research was put forward.
