Image Julian Sutton. Habitat Along streams, sometimes on disturbed slopes; 0-300 m. The Northern California Walnut became known to European science through specimens collected by the English naval surgeon and naturalist Richard Hinds, when the survey ship HMS Sulphur explored the lower Sacramento River in 1837 as part of a survey of the Pacific (Thomsen 1963).

In Europe there are a few records from England, where any without wild provenance should be examined with an open mind, considering the confusion surrounding the western black walnuts. Most commercial walnuts are grafted onto either J. hindsii itself or a Paradox hybrid, either seed raised or clonal (see below): each has its own pattern of resistance and susceptibility to fungal and bacterial diseases (University of California, Davis 2013). ex R.E.

This black walnut is endemic to Northern California and possibly has only a few native stands remaining. This is a useful and culturally significant tree. Wood taken from the graft area of orchard walnuts is sometimes used by woodworkers, exploiting the colour change from hindsii to regia wood: an example can be seen at McFadden (2019). Bark light or medium gray, splitting into plates with age. No evidence of introgression from J. regia was seen, perhaps because Paradox hybrids generally have low fertility. 4*, 5*, 6*, 7*, 8, 9, 10, 11, 14*, 15*, 16*, 17*, 18*, 19*, 20*, 21*, 22*, 23*, 24*, Annual Precipitation: 9.4" - 78.8", Summer Precipitation: 0.14" - 1.49", Coldest Month: 36.8" - 55.2", Hottest Month: 63.3" - 80.7", Humidity: 0.09" - 29.78", Elevation: -7" - 6244", Creative Commons Attribution-ShareAlike License, PRISM Climate Group, Oregon State University.
