The vast majority of alien plant species are cultivated in botanical gardens. Many of them have been assigned the status of invasive activity. One of the transformer species in the list of invasive plants of the Botanical Garden of Vyatka State University is Petasites hybridus (L.) Gaertn., B. Mey. & Scherb. Active dispersal of the species is caused by the peculiarities of its structural organization. It was established that P. hybridus is a summer-green vegetative-mobile short-rhizomes herbaceous polycarpic herbaceous polycarpic, geophyte. Due to the development of geophilic shoots, P. hybridus actively colonizes neighboring territories, and the system of shortened sympodially growing rhizomes contributes to the consolidation and retention of the developed area. We recommend to control the process of dispersal by removing a number of clones from the territory in the fall or by installing artificial fences to a depth of up to 30 cm.
