SierraCook said:As the resident Forester on the board, I think I have a little experience on this subject. Pine nuts are an edible seed of the Pinus species of conifer trees. Pine nuts grow inside of pine cones. They are very difiicult to harvest because removal from the pine cone usually takes heating. All of the pine trees have edible seeds. Pine nuts are also called Pignoli. Click on the link below for a picture of a singleleaf pinyon.
