But despite the large number of alien plants in the botanical garden, their invasion can be mostly contained. The most widespread invasive plant is Parthenocissus vitacea, in addition, a number of potentially invasive plants need monitoring, in particular Parietaria officinalis, Phytolacca acinosa, Thladiantha dubia and some others. In addition, there is a list of introductions which have high naturalization rates and over time could replenish the composition of the spontaneous flora.
