Question

What do you call a weed and why?

Answer 1

Just about any plants that grows at places you don't want them too. If carrots starts sprouting all over your lawn I'm sure you call them weed.

Answer 2

Beauty is in the eye of the beholder and when it's no longer a beautiful plant and desired then it is a weed in that beholder's eye.

Answer 3

Weed is defined as any plant growing where it is not wanted. Ever since human beings first attempted the cultivation of plants, they have had to fight the invasion by weeds into areas chosen for crops. Some unwanted plants later were found to have virtues not originally suspected and so were removed from the category of weeds and taken under cultivation. Other cultivated plants, when transplanted to new climates, escaped cultivation and became weeds. The category of weeds thus is ever changing, and the term is a relative one.
