The Story

For many people, Black Walnut is prized most of all for its heavy, dark, beautifully grained heartwood. It has become so valuable for furniture, cabinets, gunstocks, and veneer that most of the grand old specimens have been cut down… either by their owners or by poachers. “Walnut rustlers” have been known to steal mature walnut trees by cutting them down and air-lifting them out with helicopters. Pioneers destroyed many a tree in their day, too, often without a thought to the fine lumber they were wasting. They used the wood for railway ties, split-rail fences, and—gasp—firewood.

The Details

Edible and shade tree potential, Emma K is a multifunctional tree in the landscape. During the spring and summer, grab a good book, your picnic basket, and enjoy the wide canopy that Emma has to offer to escape the hot sun. As the hot summer turns to the cooler fall, watch as Emma's leaves turn a lovely yellow, and the walnuts begin to ripen. You'll want to pick the sweet, easy-to-shell walnuts and use them for fresh eating and baking; how about baking up some sticky buns with walnuts on top?

How to Grow

Black Walnut is not hard to grow in most sunny sites, but it performs particularly well in deep, fertile, moist, well-drained soils. In such a site, it can grow surprisingly fast. Many people hesitate to plant Black Walnut because they’ve been told that the chemicals it contains kill many other plants growing nearby. The science seems to indicate that this is largely a myth. You’ll want to be sure to plant your tree well away from walkways, pools, and patios, however. The nuts, encased in a thick husk, are large and heavy, and you don’t want to be under them when they fall.
