Toni, do you know if glads will grow under black walnut trees, or in the presence of juglone in some mulch? (I don't find it on any list I have of juglone tolerant nor intolerant plants and I have lots of corms to plant.)

Darius: without doing some research, I can't answer this with any authority. My understanding is that very little will grow under black walnut trees; however, I have 12 on my property, and the previous owner planted irises around the base of each many years ago. The iris seem to do fine and some of them bloom. I believe the ones that don't bloom have become covered with mulch and grass clippings over the years and the tubers don't get the sun.

If you find some answers, please share!

Thanks. I did more searching, found no answer. So, I guess I'll find out by trial and perhaps error!
