Sažetak
The study provides information about three climbing ornamental alien plants, studied in Croatia from 2016-2018. Senecio angulatus L. f. and Delairea odorata Lem. are perennial climbers originating from South Africa, classified as naturalized aliens in southern and western Europe. Senecio angulatus was first reported in Croatia in 2005, however approximately fifteen new populations (mostly in Northern Dalmatia) have been found since, mostly as decorative or rarely as a garden escapee. A small population of Delairea odorata was only reported in 1999, growing on the island of Lošinj. Here, we report large established populations of both species on Lošinj, displaying their invasive nature through vegetative propagation. They cover the Mediterranean evergreen forest understories, sometimes climbing over shrubs or even up to tree canopies, but mostly along disturbed forest edges and openings. We assume that both species have invaded through careless disposal of garden waste (fragments of stems and rhizomes that easily root) ; however, cultivated plants on Lošinj are very rarely found. Humulus japonicus Sieb. et Zucc. is an annual vine native to East Asia, reported as a casual alien in Europe since the late 19th century. It is naturalized only in a few localities, with no proof of invasiveness outside Hungary. We are here reporting a population found in 2018 as the first record for Croatia. The species was found along the Drava River oxbow, South-East from the village of Legrad (N Croatia) near the Croatian-Hungary border. It occupies temporarily inundated riparian habitat, growing along with several other invasive plant species.
