I've seen true lilies growing under black walnuts. I don't know how anything else would do, but, if you like hummingbirds, they love my Lycoris (what else do you expect me to talk about anyway??!!) If Lycoris can stand that nasty chemical, they thrive in deciduous shade, plus you can come up with all sorts of colors, plant heights and blooming seasons. We've all read Jim W.'s remarks to this effect many times. I know grasses can't handle the chemical from black walnut. Arnold Trachtenberg wrote: > James; > > I have a question and then a suggestion.

Not all plants are affected by juglone. -- Mr. Kelly M.
