Inventory - Species:
Claro Walnut
juglans hidsii

Origin:  Claro Walnut is found primarily in northern California. These trees can grow up to 5' or more in diameter. Claro Walnut trees are used as the root stock in California for growing English Walnut trees which produce most of the walnuts that we eat. (English Walnut trees will not grow in California soil so they need to be grafted to Claro Walnut trees.) Sometimes slabs cut from these trees produce lumber with both species of wood and an interesting graft line detail. Furniture made from this lumber make great conversation pieces!

Color:  Claro Walnut is a little darker than American Black Walnut. The heartwood can range from a light brown to a dark chocolate brown with light and dark brown streaks. The color can sometimes have a gray, purple, or red hue to it. The sapwood is usually an off-white color. Claro Walnut often has varying degrees of burly or curly figure and its color can be beautifully variegated.

Janka Hardness:  1130 (medium-hard) Similiar in hardness to Black Walnut.

Decay and Weather Resistance:  Rated as very durable in regard to decay resistance.

Workability:  It is very easy to work with assuming the grain is straight and regular; you may have tear-out when using the planer if the grain is irregular. Claro glues,stains, and finishes well. Because of the high demand and limited supply for this beautiful wood it can be expensive especially in large sizes and long lengths.

Uses:  Claro Walnut is a very stable wood making it ideal for wide Nakashima style table tops or gun stocks. Its interesting variegated color makes it highly sought after for high end furniture, cabinetry, musical instruments, venner, and turned items.
