The Black Walnut (Juglans nigra L.) is one of our most common native trees. We have many of these trees in the woods near the yard and right now, they are absolutely filled with walnuts and their foliage is bright yellow, very pretty against the blue sky today. An interesting note about these Black Walnuts — they produce a chemical called juglone, which is toxic to many other plants. This chemical is very concentrated in the roots, buds and hulls of this tree, and also present in smaller quantities in the leaves and stems. A lot of plants are very adversely affected by this chemical and turn yellow, wilt and eventually die if planted too close to these trees. Some of the plants that are very sensitive to this chemical include azaleas and rhododendrons, peony, autumn crocus, birch, silver maple, tomatoes, peppers, eggplant, potatoes and cabbage. Some plants that are tolerant of Black Walnut trees are daffodils, iris, daylilies, liriope, phlox, Shasta Daisy, beebalm, cedar, euonymous, beans, onions, corn and beets.

It is a brilliant shot against the blue sky! Now, are these edible? You would not believe the length my brother has to go to keeping his English Walnut going.
Thanks, Christine. Yes, they are edible. They’re not easy to get the hull off and crack open though, and they always stain your hands. My mom used them in chocolate cakes years ago. There are so many of them around here — the squirrels get most of them now.
The wood from these trees is very pretty and very valuable. We have a fireplace mantel made from black walnut.
Sherry ..that’s a beautiful walnut tree foliage against the blue sky…
I love your new title picture..that is absolutely beautiful…so autmn..
Thanks, Raji. The walnuts are somewhat of a nuisance right now, with the walnuts falling off everywhere, but they are pretty in fall.
Thanks also about the header, the mountains here are really pretty right now.
