There is a relationship between cultivation of plants and mankind since the earliest human organizations. The use of plants in home gardens is a tradition that has been passed down from generation to generation in certain localities. The aim of this research was to verify the occurrence of home gardens in different cities of three Brazilian states, besides knowing the use of cultivated plants for feed, medicinal and ornamental purposes. This study was carried out in cities of three Brazilian states: Mato Grosso (Cuiabá and Cáceres), Sergipe (Aracaju and Lagarto) and Paraná (Curitiba and Campo Mourão) located in different regions of the country (Midwestern, Northeastern and Southern). Semi-structured interview were performed with residents of the state capital and countryside. Data were evaluated for popular knowledge regarding the use of plants and plant structure. Most interviewers have gardens with plants. Greater cultivation and use of food plants was observed by the interviewees, with the exception of Aracaju city. Residents in countryside had higher habit to cultivate plants when compared to people residing in the state capitals. Among the plant organs most cited the leaf stood out. Thus, it is concluded that there is a great practice of cultivating plants in the studied cities, however the use of plants varies from one region to another
