Butternut (Not recommended)

Butternuts.
Due to susceptibility to butternut canker, butternuts are not recommended for planting anywhere in this region and usually require removal and/or replacement. Butternut, also called white walnut, is a native tree found throughout the Midwest in moist, well-drained soils. Butternut canker, an introduced fungus, has killed off many native stands of butternut. The tree is related to black walnut and is also allelopathic. The wood is prized for the wood and the fruit produces a yellow dye that was used in the Civil War to color uniforms. "This species is native to the Chicago Region according to Swink and Wilhelm's Plants of the Chicago Region, with updates made according to current research."
