Invasive plants - usually each state lists what they consider invasive and some states actually fine you for having them. Our weather patterns are changing and this may also cause plants to migrate into other zones. Invasive plants do not actually feed the wildlife tho insects are not always so choosy. Same for poisonous plants, but poisonous plants can feed the insects.
Let the buyer beware is a common saying in the USA since buying anything is possible, but having it - could come back to bite you.
Education and teaching are different subjects...YOU are responsible for your education, teaching a subject is a paid job. We offer resources when asked about good places to find your research, but it always comes down to you, yourself, wanting to learn.
