The annual growth rate of mental illness is between 3.3% to 6.6%. Fifty percent of mental illness patient has catastrophic illness certificate because of chronic schizophrenia (Ministry of Health and Welfare,2022). Auditory hallucinations, delusions, emotional disturbances, and disorder in behavior and the poor ability of speaking are common in patients with schizophrenia. These symptoms lead to reduce the cognitive and executive function, resulting severe impairment of eventual daily living functions and social interactions. Thus, the cost of hospitalization and medical fee is increased. It is worth considering the appropriateness of the model of care. According to researches, people with schizophrenia still strive to pursue a happy and satisfying life. However, statistics of satisfaction and happiness are still lower than people who are healthy (Palmer et al., 2014; Fervaha et al., 2016). The American Horticultural Therapy Association (AHTA) pointed out that horticultural therapy increases the well-being of participants through active or passive participation in plant-related activities. It also helps participants learn new skills or regain lost skills. Furthermore, psychiatric symptoms, recovery outcomes, life satisfaction, and the benefits of social function are significantly improved (Lu et al., 2021; Oh et al., 2018). Taiwanese scholars mention that combining horticultural activities and group psychotherapy improves the therapeutic results. It means that using of flowers and plants in gardening combines with the therapeutic advantages of group psychotherapy, mental illness patients can benefit more from it (Lin, 2016). This study aims to explore the experience of patients with chronic schizophrenia participating in horticultural group therapy.
