There are many problematic non-native invasive species in the UK. The Wildlife and Countryside Act 1981 contains a list of species within Schedule 9 that you could be prosecuted for planting or allowing to spread into the wild. There are also species that are not yet on the list, that cause real problems in gardens and on development sites such as horsetail and running bamboo varieties.
