Juglone

I am not sure that my text from my phone actually got to you. Can I plant forget-me-nots near my black walnut tree? Thank you

I found only one site with lists of juglone-tolerant or sensitive plants with forget-me-nots on it (there are many such lists). Unfortunately, it lists forget-me-nots as sensitive:

Most of these lists are anecdotal. You'll even find the same plant listed as sensitive in one list and tolerant in another. The best you can do is try different things. Here are some other lists:
