Host your own Gathering with these natives that live carefree under black walnut (Juglans nigra), butternut (Juglans cinerea), and hickory (Carya spp.)—all produce juglone, a toxic compound that kills rhododendrons, lilacs, peonies, and many other useless old-fashioned garden plants. Stop the chainsaw and plant some ride-or-die fans of the Juglans family! Whoop, Whoop!
