I'm a relatively new gardener so am always looking for good advice. A year ago I moved into a new (to me)house. I have a huge garden that is surrounded by 5 huge black walnut trees. They form a fairly high canopy but I still struggle with too much shade. In addition, I am trying to find plants that will tolerate the juglone secreted by the black walnut trees. I've found some information on the internet about plants to grow and have tried plants myself to see what happens.

But, I'd like to hear from other gardeners struggling with the black walnut situation to hear about plants that you've successfully grown. Anybody out there????

Hi Susan, I'm just searching around the net for notes and information about black walnut trees myself! In the 10 years we have lived in our house, which shares a huge black walnut tree with a neighbor (it's on his property) I've had good luck with some of the following, which I usually start from seed: Painted Daisy (P), Gaillardia (P), Campanula (P), Portulaca (A) and Hollyhocks (B). The Campanula in particular re-seed very well, and we also have good luck with Spiderwort (P), which also sends out babies that seem to thrive. I've got sage, chives and thyme plants that come up every year, but basil is hopeless in this location. For spring flowers try the grape hyacinthe, but beware, they will try to take over! Good luck! Margie

Hello Susan! My niece told me that you can add the following to that list that Margie gave you. Astilbe, Bleeding hearts, and Lily-of-the-valley. Good luck!

Wow, 5 Black Walnuts. That is certainly a lot of shade. Under my one Black Walnut I have a large thriving Rhododendron, 4 kinds of Astilbe, Sword Fern, Dicentra, Centaurea Montana (comes up everywhere). Nearby within the leaf unbrella I grow 3 varieties of Blueberries, Solomon Seal (I hear it is difficult to get rid of) & Clematis armandii(evergreen), & Forsythia. Recent additions include Hosta Plantain Lily & Phlox. the only thing which hasn't been prolific is the small Blue Hosta which has never flowered in 3 years, haven't investigated why yet - I have 3 young boys and one old boy to look after too. Best of luck!

Hi Susan, We too have some black walnut trees that have caused us concern. We had considered cutting it down but it is a beautiful plant. We have done two things. The first was to open up the centre of the tree by pruning which allows more light through the canopy. (Don't do this yourself unless you are qualified, it is a dangerous task.) Secondly, we collected a list of plants that accept both shade and juglone. Two plants that I haven't seen mentioned are peony and burning bush. The peonies don't always blossom because of the shade but they do provide a nice foliage. The burning bush (Alatus compactus) will do well if you have the space. Daylilies do very well here, too; we have three varieties in the area. (Yes, they can accept some shade.) Good luck

Are there any vegetable plants that are resistant to Black Walnut poisoning. I am aware of flowers and shrubs, but am I doomed to grow nothing but flowers or can I reclaim my vegetable garden from these poisonous monsters?

Hello everyone, I live in London Ontario zone 6a, and I would love to have a privacy hedge but the area is within the danger zone of a huge walnut tree. Anyone have any ideas on what to grow? Ideally I would like a very tall hedge to afford privacy from second storey neighbouring windows. Thanks

Hi Ron.. have you given any thought to bamboo?? Very pretty and makes a nice rustling sound in the wind.. there are many hardy ones out there now... WARNING: YOU WANT A CLUMPING VARIETY, NOT A RUNNING VARIETY!!!!

I also enjoy the shade of 5 Black Walnut trees and have great success with virbernum shrubs such as the Snowflake variety and one that has leather like leaves that retains its leaves all winter long.We also have a variegated Mock Orange shrub, Rose of Sharon and a variety of Hostas. We love the shade from the trees so I have experimented with different shrubs. Our rhododenrons did not do well under the Black Walnuts.

Thanks for the advice, but I have never seen any bamboo growning in this area. Do you know where I might find info on how to grow it etc?

Hi Ron, there are many hardy bamboos now... there is a new one coming to the nurseries this spring called Fargesia robusta "Green Screen", this is a clumping one..so that is good and very hardy, also if you type in Bamboo World on your search bar, a site comes that will be very helpful and you can order from them as well, they are in Chilliwack, B.C. hope this helps

Hello again.. further investigation shows the new "Green Screen" one is hardy to zone 5 but in that zone can be deciduous.. but still hardy, try the bamboo world site i mentioned, i was on there today and they have others that are hardy to -33!!! They even have a banana tree that is fine to minus 29.. the site also tells how to grow them, what they like etc..

The best listing I could find by Googling is this one, listing trees,shrubs,veggies,perennials, and annuals too. It's a long address, so take care typing. You may need to double-check your garden books for individual plants. All my plantings bloom, with only mid-to-late afternoon sun. http://www.uwex.edu/ces/whort/landscape/juglone.htm#Trees&Shrubs

Hello, I was just trying to find the site you listed above for a good listing of plants that will survive my one large black walnut. However the site has either expired or could it be incorrect? First I wrote it down and then copied it in my address box, then I copied and pasted it into my address box and both times it said the page could not be displayed? If any one knows of an up to date listing of plants and shrubs that will grow with this blasted tree, it would be really appreciated! I live in a zone 5, in Wisconsin. I do have luck with my day lilies, sedums, black eyed susans, cone flowers, ferns, ribbon grass, Monardia, lily of the valley, astilby, tetarian honeysuckle (invasive), and I can't forget about my hostas. But one thing I can't find is any vines. A vine and some taller ornamental trees or shrubs would be great. I had always thought that jug lone was an acid, and that acid dwelling things like hydrangea and azaleas would fair well, but I am reading differently. Does anyone know why?
