Horticultural therapy and flower arrangement are addressed to all groups of patients: children, elderly people, people with impaired psychophysical and mental disabilities, physical and sensory dysfunctions, as well as ones ad-dicted to drugs, alcohol, etc. Horticultural therapy can take place in gardens located at hospitals, nursing homes, centers for drug addicts, as well as in therapeutic-profiled agriculture and horticulture farms. The aim of the article is to present results of studies on the positive effects of plants on human and selected examples of using gardens as an auxiliary element in rehabilitation. Since the 30s of the twentieth century, the said alternative form of the therapy is popular in the United States, Australia, Canada, Japan, Britain, Germany, the Netherlands, Belgium and the Scandinavian countries. In Poland, St. Louis Hospital in Krakow is a pioneer in this field. Color, shape, smell, texture of plants and landscape architecture, the sound of water in a fountain, birds voices, wind rustle, and talks with other people present in the garden, all stimulate the sensory organs and make rehabilitation more attractive. Touching plants, inhaling the beautiful scent and performing horticultural activities lead to a reduction in psycho-logical tension and stress. The horticultural therapy greatly supports rehabilitation by strengthening of muscle, im-proving coordination, balance and general physical strength.
