Plants Tolerant to Juglone
The following lists of plants tolerant to juglone were compiled from published sources. They are based on observation under various settings, but few plants have been experimentally tested for sensitivity to juglone. The plants highlighted in green are species I have personally observed growing seemingly unhindered in and around the under story of Juglans regia.

Many factors affect sensitivity, including level of contact, health of the plant, soil environment, and the overall site conditions. Aside from juglone, a mature walnut will cast a very heavy shade and young sun demanding plants will not survive in these conditions. The lists provided here are strictly guides and cannot be considered complete or definitive.
If you have experience of plants growing well under and around a Juglone producing plant that are not on this list, please share in the comments section below.
