Weeds in the Desert Southwest

What is the Merriam-Webster definition of a weed?

A weed is any plant that is not valued where it is growing and is usually of vigorous growth; especially: one that tends to overgrow or choke out more desirable plants.

In other words, a plant that is growing where you don't want it.
