I, too, would love to know what type of wood this is. A friend of mine gave me some pallet wood and in the mix was some wood exactly like this. Took a few shavings off to clean it up and, you’re right, it planes nicely. I’ve been hanging on to it for just the right project.
Attached are some close-up pictures of the wood freshly exposed. It starts off light in color and darkens quickly, to the point it is the dark color you see in the finished project, within a week’s exposure.
As to some questions: By locally grown I am referring to southwest Missouri, I do not notice any aromas while cutting the wood, and it has not been stained. The only finish on it is shellac sprayed from a can.
After researching it further, especially how the wood start reddish orange when freshly cut, darkening substantially over time to a reddish/purplish brown to nearly black, I believe this is Padauk. It is just curious that it would have been found in the rough with a stack of rough Walnut. Thanks for the help.
