That’s basically the definition of a weed.

Weeds aren’t a specific type of plant, it’s a description for any plants that grow where they are “not supposed to”, typically in a way such that it’s hard to stop them from growing. They spread easily and are hard to fully kill off.

We have plants that people like, such as lemon balm and mint, for example, are tasty herbs…that are also weeds. They grow like CRAZY and will dominate a plot of not pruned back often.

So basically weeds are just “plants that are good at spreading to and growing in lots of places and hard to get rid of”. And as such… they’re plants that are good at growing in lots of places.
