Aside from numerous advantages, urbanization also has certain drawbacks, among which it is worth highlighting the often irreversible loss of green space as a result of constructing residential buildings, transportation infrastructure, etc. One of how the loss of green spaces, which have a positive impact on the quality of life in cities, can be partially compensated is through the construction of rooftop gardens. Rooftop gardens have many benefits that enhance the ecological, economic, and social structure of the city, and they are divided into two main categories: intensive and extensive. Intensive gardens offer more possibilities, with the most significant one being the cultivation of agricultural plant species. Extensive rooftop gardens offer fewer possibilities than intensive ones due to the thickness of the substrate. This study aims to justify the advantages and potential disadvantages of green roofs as an important component of green construction, to propose ornamental plant species suitable for application on the mentioned roofs, and to explore crops that would be suitable for limited food production within such a specific habitat.
