What does “wild wenwan walnut” mean?

This is an English reading overview of the Chinese article, rather than a complete translation. The Chinese source has been updated since this overview was prepared; consult the original for the latest details.

The central idea

Wild describes a walnut’s source in naturally growing, ungrafted trees; seed-grown describes propagation from seed. These terms are not interchangeable, and a mountain-source label alone does not establish quality. Verify the actual source and condition. The separate wild-versus-grafted guide covers the comparison between those directions.
