The city of Yamoussoukro is full of many green spaces. Ranging from roadsides trees to abandoned spaces through private gardens, we are witnessing a massive and uncontrolled introduction of various ornamental plants. Thus, the general objective of this study is to evaluate its diversity. The plant species were identified using the itinerant method. The results obtained showed that the green spaces of the city of Yamoussoukro are rich in 212 ornamental plants, most of which are exotic (65%). Tree species are the most numerous (75%). Among the ornamental species planted, there are 13 invasive species of which the majority (10) is exotic. This presented the situation of planted ornamental species and drew attention to the introduction of invasive ornamental species that can modify local biodiversity.
