Additional comments: Italian stone pine is an absolutely tough lollypop-shaped pine that can be used in coastal or desert areas in the American southwest. However, it is not a commonly found in the Phoenix area. Italian stone pine has tasty pine nuts. The tree has been cultivated for its nuts in Europe for over 6,000 years, and harvested from wild trees for far longer.
