Ok Permies! Let's put together a list of permaculture plants that we know work (or don't work) under a juglone producing walnut tree. Please only list plants that you've had personal experience with, don't repeat a list you saw online somewhere. I'm hoping this will get at some of the important questions like "Will aronia work under a walnut?"
If your addition to the list is well known, feel free to add it directly to the wiki (if you have access). If it's a rarer plant, you don't have access to edit the wiki or you think people may have other experiences, please reply to the thread to list you plant(s). I'll add it to the wiki and then we'll know who to ask if we have questions.
