what is this plant/weed please?
I cannot answer your question on this plant. We would need to know where this is found, along with a photo of its flower or fruit to help us identify it. How long it has been at this site? Is it a perennial or annual? Our knowledge is limited to plants that grow within our region. The flowers and fruit are the main way we can identify plants by their family. If you can give us a bit of feedback we may be able to help. Without that information there are just too many look alikes across the world.
