Here in Australia we get the thistle weed. Does America get the same weeds as we do in Australia or no? Weeds in Australia are environmental means they spread everywhere. Some weeds are foreign and Just make there way through Australia. I don't know if there is any such thing as a common domestic weed that grows naturally in a country or are all weeds just environmental? Domestic meaning a weed that grows native all around a particular country but only grows in one country. Please lets chat about this! It is a good topic.
