Chinese classical gardens serve as restorative environments that epitomize the essence of Chinese aesthetics. Despite their recognized Outstanding Universal Value, research on the multisensory experiences and associated well-being benefits they offer remains insufficiently explored. This study examines the Humble Administrator’s Garden through a multisensory framework incorporating visual, auditory, and tactile dimensions. By employing a mixed methods approach that integrates questionnaires and physiological measurements, we assessed the psychophysiological responses of 78 participants before and after entering the garden, as well as at distinct landscape points. Key findings reveal the following: (1) the traditional garden environment evoked significant positive perceptual effects; (2) the garden, with its diverse combination of landscape elements—including architecture, water features, rock formations, and plants—was strongly associated with enhanced well-being outcomes. A higher diversity of visual landscapes yielded more pronounced benefits, with water features exerting the most substantial positive influence on health, while rock formations showed a comparatively lesser effect; and (3) physiological and psychological responses of participants varied within the same landscape setting, with tactile experiences eliciting the most profound psychological changes. These findings underscore the pivotal role of multisensory engagement in Chinese classical gardens for fostering well-being, offering valuable health-related benefits beyond their cultural and ecological significance.

Amid growing “nature deficit” associated with urbanization and indoor living, flowering plants are increasingly used to support psychological restoration. Yet evidence on how floral color and structural morphology jointly shape restorative outcomes remains limited. This study employed a within-subjects, repeated-measures design, utilizing physiological instruments and psychological questionnaires to investigate the physiological and psychological restorative benefits of Hydrangea macrophylla and to quantify the differences in restorative effects across five colors (blue, pink, white, mauve, red), two inflorescence types (mophead, lacecap), and two petal structures (single, double). Twenty-eight healthy young adults viewed 15 live hydrangea stimuli under controlled laboratory conditions. Multimodal outcomes combined objective measures—eye-tracking and single-channel EEG—with subjective measures (SD; POMS). Hydrangea exposure significantly reduced negative mood, and color and structure exerted distinct and interactive effects on visual attention and arousal. Red and mauve elicited larger pupil diameters than white and pink, while lacecap inflorescences were associated with lower cognitive load and improved attentional recovery relative to mophead. Double-petaled forms showed greater attentional dispersion than single-petaled forms. Interactions indicated that morphology modulated color effects. The mauve lacecap double-flowered cultivar (M02) showed the strongest observed restorative potential within this sample. These findings highlight the importance of integrating color and structural cues when selecting flowering plants for restorative environments and horticultural therapy, and they motivate field-based replications with broader samples and higher-density physiology.
