Butternut, also called White Walnut, is a native nut tree of eastern North America producing elongated, sticky green husks enclosing richly flavored, oily nuts prized by wildlife and humans. The tree grows 40–60 feet tall in rich, moist upland and bottomland forests. Butternut is severely threatened throughout its range by Butternut Canker, a fungal disease that has devastated wild populations. Finding a healthy Butternut is increasingly rare, making it a conservation-priority species.
