Is alfalfa a noxious weed

No, alfalfa is not considered a noxious weed. It is a cultivated legume known for its high nutritional value and is often used as animal feed, particularly for livestock. While it can spread aggressively in some areas, it is generally valued for its benefits in agriculture, such as improving soil health and providing forage. However, in certain contexts, it could be viewed as invasive if it outcompetes desired plants.
