Horticulture is a branch of agriculture that deals with the cultivation of fruits, vegetables, flowers and ornamental plants. One segment of horticulture is ornamental horticulture, which deals with the cultivation and maintenance of ornamental plant species. The aim of the work is to carry out an inventory of the assortment of ornamental plant material of the selected garden center and to determine their invasive potential by reviewing the recent literature. Invasive plant species are those species that have been intentionally or accidentally introduced into an area that is not their natural habitat. The focus of the research was on the garden center, the "Stella Floris" nursery, which is located in the area of the city of Čakovec. In the paper, all the plant species that exist in the offer of the garden center are analyzed and presented in detail, and those ornamental species that have invasive potential are especially singled out. The nursery "Stella Floris" has a total of 264 plant taxa on offer on over 7,500 m2. The most represented plant taxa are from the Pinaceae family (36 taxa) and the Cupressaceae family (35 plant taxa). There are several invasive species in the nursery: Berberis thunbergii DC, Robinia pseudoacacia L., Acer negundo L., Imperata cylindrica (L.) Raeusch, Wisteria sinensis (Sims) DC. and Buddleja davidii Franch.
