  In this paper we compiled data on 157 Hungarian adventive plant species – of which 65 had not been reported from the country previously – from 47 settlements of Transdanubia and the Great Hungarian Plain. These taxa are rare, interesting or not included in the most recent list of the Hungarian neophyte species. The list includes data about many rare, occasionally escaping species (e.g. Lagurus ovatus, Salvia coccinea), taxa considered incapable of reproduction under the recent climatic conditions of the Pannonian Basin (e.g. Cupressus sempervirens, Punica granatum) or naturalised plants that may become invasive in the future (e.g. Celtis sinensis, Lonicera japonica). In the outlook we highlighted some special urban habitats (e.g. private and botanical gardens) and practices (e.g. public green space management) that endanger the native flora. We also describe their role in promoting the appearance and the expansion of alien plant species, and processes (e.g. laurophyllisation, spread of thermophile species) that will become increasingly common in the future as a result of climate change.
