"noxious weeds"

I've been using the weeds to prepare planting beds. We have an abundance of "noious weeds" here. Kochia and various forms of knapweed. Goats go crazy for knapweed, but usually only as it's beginning to flower. They like kochia when it's young. It makes great deep litter for chickens when mature; it's got lots of high protein seeds that they love. In the spring, it goes in the compost.
When researching plants, use the botanical name. I found out more than "it's a noxious weed, get rid of it". These plants are used as forage during drought. They are deep rooted plants that are drought tolerant.

Most of what are called weeds are very good first colonizers, which lay the groundwork for plant succession after a catastrophic disruption event.

As you are finding out, botanical (scientific) names will allow you to find more and more pertinent information than going searching by "common" names.
