- Description
-
Butternut is a medium to large shade tree in the walnut family. It is native to moist bottomlands, lowland forests and some drier limestone soils in eastern and midwestern North America. The nuts shells can be hard to crack but the nuts are sweet and oily and prized by humans and wildlife.
Plant in moist well-drained soil in the full sun. It does not tolerate shade or competition. Established trees tolerate drought and browsing by rabbits. As with black walnut, butternuts produce juglones which are toxic to other plants. The effect usually extends out to the drip line.
However, the tree is endangered in its native range due to butternut canker disease and overharvesting. The canker has devastated the tree and there is no cure. It is not often used ornamentally but as a native tree, it is worth saving.
