Invasion of mimosa in London

Question

Is there a body of people in London who stop garden centres from selling potted trees that look cute when small but become invasive, such as the mimosas, fruit and even those used in our streets that quickly become huge. Especially as people are now putting up extentions that are so ugly or over look people that they think these type of trees will quickly deal with the problem, only to find trees spreading across their own garden or invading others and blocking their light. This causes too many problems with neighbours to deal with and it is becoming a huge problem in the Dollis Hill area in London.
