I am not sure we would have to condemn a plant as a weed but a forum that discussed what they looked like and their habits and how to get rid of the unwanted plants in the garden setting could be informative.
It could also call out the eatable ''weeds'' such as purselane is a very tasty and nutritious weed here.
I have often told people you don't have to know the name of every plant in the garden just the weeds and pull them
