Juglans cinerea, or butternut, native to eastern and midwestern North America, Ontario, is currently endangered due to the invasive butternut canker disease, which has devastated its population. It prefers deep, moist, well-drained soil, preferably with alkaline conditions to accommodate for their long tap root. While restoration efforts are underway, planting should be approached with caution, as the disease is widespread. Black walnut closely resembles butternut and provides a safer planting alternative, as butternut is also prone to blight, fire, storm damage, and grackle damage. Butternuts tolerate drought and browsing by rabbits but produce juglone, toxic to other plants. It sheds abundant leaves and hard-shelled nuts, leaving significant debris and residues on nearby surfaces, making it extremely messy. Despite these challenges, the tree has historical value, with its fruit once used for dye and its sap boiled for syrup.
