Summary
Juglans microcarpa, commonly known as Little Walnut or Texas Walnut, is a deciduous tree or large shrub native to the South-Central United States and Northeast Mexico, where it is often found along streams, rivers, and in moist, well-drained soils of floodplains and arroyos. It typically grows to a height and width of 15-20 feet (5-6 meters), with a rounded canopy that provides light shade. The bark is rough and deeply furrowed, and the pinnate leaves turn yellow in the fall. Little Walnut produces small, round nuts encased in a thin husk, which are an important food source for local wildlife.
Little Walnut is valued for its adaptability to various soil types and its ability to thrive in both full sun and part shade. It is relatively low-maintenance and can be used in naturalized plantings, as a specimen tree in smaller landscapes, or for restoration projects. It is drought-tolerant once established and can handle periodic flooding, making it suitable for riparian plantings. However, it is susceptible to walnut blight and should not be planted near vegetable gardens due to juglone, a compound it secretes that can inhibit the growth of sensitive plants.CC BY-SA 4.0
