Estimated Native Range

Summary

Juglans hindsii, commonly known as Northern California Walnut, is a deciduous tree native to the riparian zones, valleys, and foothills of Northern California. It typically grows to a height of 18-48 feet and a width of 15-45 feet. The tree is characterized by its rounded canopy and pinnately compound leaves, which turn yellow in the fall. The bark is rough and deeply furrowed, and it produces round, edible nuts encased in a thick, green husk. Flowering occurs in late spring, with male flowers in drooping catkins and female flowers in short spikes; however, the flowers are not particularly showy.

The Northern California Walnut is valued for its hardy nature and the provision of shade and edible nuts. It is utilized in traditional and wildlife gardens, habitat gardens, natural landscaping, and climate-compatible drought-tolerant gardens. It is also a key species in habitat restoration projects. This walnut tree is adaptable to a range of soil types, provided they have medium drainage, and it thrives in full sun to part shade. While it requires medium amounts of water, mature trees can tolerate some drought. Gardeners should be aware that the roots produce juglone, a compound that can inhibit the growth of certain plants nearby. Additionally, the tree can be susceptible to walnut blight and root diseases in poorly drained soils.CC BY-SA 4.0
