Group workshops in horticultural therapy offer activities such as planning and maintaining vegetable gardens and greenhouses. The goal is to promote social participation, relaxation, responsibility, and well-being through contact with nature. For several years, the Douglas Institute has maintained a horticultural greenhouse and gardens, offering workshops to people receiving care. The Institute is a pioneer in this field in Québec and across Canada, at a time when the benefits of horticultural therapy are well documented across North America, Europe, and Asia, and its popularity continues to grow worldwide.
