Notes

Native to South America, but occurs in southern, western and central Europe, North Africa and North America as an alien introduced as an ornamental ( Mokni and Verloove 2021), with some recent Hungarian records ( Mesterházy 2021). These are the first records of the plant from Budapest. Aside from these records, the authors found a small population at the bank of the Danube, north of Budapest. The plant might become invasive.
