Black Walnut curse

waukesha, WI(Zone 5a)

Have a huge old black walnut tree and am looking for some recommendations for plants that will thrive under it. I have a list from Iowa State U. but lots of them are bulb type plants that are early spring bloomers and I'd like to see some color throughout the growing season. I'm zone 5, if you've had some success in combating the juglone from this tree, tell me about it!

Granbury, TX(Zone 7b)

I found mints do well under black walnuts..

and I also found this link to a pdf file with some excellent info..

WOW! Thanks Kathleen, that was quite a list!! That should help this year, and I can't wait to get started! Fortunately, I have a number of the perennials listed already established in other spots in the yard, so I can really do this on the cheap. So many of them have been donated by friends and have thrived, so they will be sturdy enough to be moved. My mantra is "If it's free, take it and put it somewhere...."

south central, WI(Zone 5a)

Hi, I went through the catalog of my local grower. In addition to Kathleen's list, they had the following marked as Juglan tolerant.
Amsonia,aster (lateriflorus, novae-angliae, novi-belgii), Jack-in -the-Pulpit, white and blue baptisia, chelone (turtlehead), coneflower, maidenhair fern, penstemon-Husker Red,tiarella,lobelia (tall form) peony-lactiflora.
These are all hardy here in WI.

Tellico Plains, TN(Zone 7b)

You mean I have another excuse to buy more plantz ? LOL

Panama, NY(Zone 5a)

LOL, did you NEED an excuse????????

Hughesville, MO(Zone 5a)

I've grown hostas under a black walnut for several years now. The clumps keep growing and doing well.

Lancaster, OH(Zone 5b)

I'd be careful planting any Rhododendron under a BW. I lost a rhododendron-grandiflora. I relocated by climbing rose in time to save it but it didn't like the BW at all. I'm curious as to whether a bittersweet will do well under BW. Also wondering if I cut the BW down (because of the mess), how long before the roots are no longer toxic?

Tremont, IL(Zone 5b)

I have H. Royal Standard & Day Lilies growing under my BW tree.

Maben, MS(Zone 7b)

I have wisteria,Ivy,Mexican Petunia and Stone Crop Sedum under mine that are doing great.
