Where does alfalfa grow in the US?

Alfalfa is primarily grown in the western and central regions of the United States, with significant production in states like California, Colorado, and Wisconsin. It thrives in well-drained soils and areas with ample sunlight, making the arid and semi-arid climates of the West particularly suitable. Additionally, it is also cultivated in parts of the Midwest and the Northeast, where irrigation can support its growth.
