© 2019 CSIC. We provide the first records of five non-native vascular plants for Europe—Commelina erecta, Cylindropuntia fulgida, Dasylirion serratifolium, ×Graptosedum and Senecio crassissimus, two for the Iberian Peninsula—Lobelia laxiflora subsp. angustifolia and Pennisetum flaccidum, and four for Catalonia— Dimorphotheca fruticosa, ×Gasteraloe beguinii, Opuntia elatior and Tradescantia sillamontana. In addition, new local records are provided for ten taxa scarcely reported for Catalonia. During the last decades, ornamental horticulture constitutes the most important source of alien plants, and some of them are potentially invasive species at a worldwide level. Most of the plants listed in this study are escaped from gardens or established as a consequence of dumping green waste. Some species are locally naturalized and in some cases they could behave as invasive.
