Claro Walnut Burl Yarn Bowl Number (6778)

​Claro Walnut (Juglans hindsii (also J. californica)) also known as California Black Walnut. Heartwood can range from a lighter pale brown to a dark chocolate brown with darker brown streaks. Color can sometimes have a gray, purple, or reddish cast. Sapwood is nearly white. Wood from orchard trees that have been grafted with English Walnut (Juglans regia) may have a colorful/streaked appearance near the graft, which is sometimes referred to as “marbled Claro Walnut.” Claro Walnut can occasionally also be found with figured grain patterns such as: curly, crotch, and burl.

Claro Walnut is a commercially important tree species that’s used as root stock on walnut orchards. The robust roots of Juglans hindsii are well-suited to the California climate, and are combined with grafts of English Walnut (Juglans regia) to produce a higher yield of walnuts. Another closely related species, Juglans californica, has a distribution that is farther south than Claro Walnut, and is sometimes referred to as Southern California Black Walnut; some sources consider these two to be the same species with simply two varieties.

Claro Walnut is from California and Oregon.
