Town of Split is located in the middle part of Dalmatia region, on Split peninsula, which closes the Kaštela bay along with the island of Čiovo. It's position makes it suitable for growth and development of many plant species. The goal of this research is to determine floral composition of ornamental vascular plants in Split city area. To conduct the research it was necessary to visit many different locations and to note inhabited ornamental plant species. To consistently present ornamental vascular plants in Split urban area, taxonomic analysis of plant species is conducted, as well as plant life form analysis, analysis of floral elements and the share of alien and native species. Most represented family of ornamental plant species is Rosaceae, the highest percentage of plants are cultivated and adventitious, and have Phanerophyta life form. There are more native than alien plant species, but their share is not significantly higher. Furthermore 12 invasive plant species are found in Split urban area. Comparison of ornamental vascular flora of Split with researches of other urban floras resulted in cognition of Split's rich and diverse ornamental flora which can easily be applied and maintained to improve quality of life in Split.
