The issue of stress among urban residents is becoming increasingly serious, affecting both physical and mental health in cities in China. Pocket parks serve as essential green spaces for people’s well-being in high-density urban environments. However, limited empirical research has examined how plant landscape components support stress recovery among urban residents, particularly in the context of pocket parks in China. This study investigated the effects of plant species richness and plant landscape types on stress recovery, with a focus on the mediating role of perceived aesthetic quality. A pre-test and post-test design were conducted in six selected pocket parks with different landscape characteristics using questionnaire surveys. A total of 605 urban residents were recruited using a random sampling method at different sites. The results indicated that medium plant species richness (t = −10.502, p p
