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 commonly found in the Phoenix area for reasons other than its rounded shape that are not clear to me - it's a great pine for the larger desert mesic and oasis urban landscape spaces. 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.
