Hello! I know that generally, peonies are on the list of shrubs/perennials that do not tolerate juglone. However, I do know that our neighbor has many peonies that have thrived for over a decade well within the drip line of their mature black walnut tree. My neighbor thought she recalled that it was the specific type of peony that is tolerant. I am aware that there are the lactiflora, itoh, and hybrid varieties, and I’m just wondering if you can advise me as to which type does in fact tolerate juglone. Thank you!
