The word "walnut" comes from Old English "wealhhnutu," which means "foreign nut" because the walnut tree was introduced to England from Gaul. Over time, the term evolved into "walnut" as we know it today.
Cut it down. Some species are not self-pollinating, but the "English" walnut is, so there's no reasonable way to keep it from producing fruits.
walnuts, of course. what they mean by that is they produce walnuts. Walnut trees produce generally in the light spring or the mid fall. The walnuts they do produce happen to be large in size often. Walnut trees produce by generating small walnut seeds in the early spring that follow into the summer. By mid fall, the walnuts have sprouted & become the fruit the tree is known for.
These plants grow well in a bed around the trunk of a large black walnut tree in my garden in central Maryland (Zone 7): Black-eyed susans (rudbeckia) ; daylilies (hybrid & common), hostas (various cultivars), impatiens, tradescantia, carpet bugle (ajuga reptans) Also growing well nearby (under walnut tree canopy but about 4 feet from the trunk): two sedum cultivars, monkshood (aconitum carmichaelii), honeysuckle cultivar; pink turtleheads (chelone lyonii), climbing eunonymus, Virginia bluebells, None of these plants are adversely affected by the tree's supposed toxins.
It has a rather nasty poem written about it. "A dog, a wife and a wall nut tree, the more you beat them the better they be." This refers to the fact that if you beat the base of the tree with a stick early in the year this (damage) promotes production of walnuts. Walnut burr wood is also very beautiful and prized.
