One of my favorite things about Italy (although they are not of course limited only to Italy) are the umbrella or stone pines,
pini marittimi (
Pinus pinea). Italian pine nuts or pinoli come from this beautiful tree, while Chinese pine nuts (which the Italians frown upon) come from other species. I have also heard that the Chinese pine nuts cause an after-taste for some. A cluster of pines is called a
pineta.
The booful umbrella pines shown above are from Bibbona on the Tuscan seaside. Wish I were there right now.
