Part of my minute garden is (in the process of becoming) native plants/pollinator habitat, and on part I grow tomatoes, kale, squash, and beans. (Yes it's crowded!) I'd like to plant a winter cover crop but have just learned that red clover is invasive. The name "purple prairie clover" doesn't exactly scream "Northeastern US," but would that be a reasonable choice? Or -- ?
Thank you as ever!
